cies very disimilar to each other; and our author proposes to reject such as are known to be fuci

, or have a strong analogy to the fuci; as well as thofe which are terrestrial and gelatinous, or which approach to a globular form.

The character will then be better adapted to the species, of which, with these limitations, he has subjoined a synopsis, including fome new fpecies.

XIII. Account of a Species of Bark, the original QuinaQuina of Peru, fent over by Mons, de la Condamine to Cromwell Mortimer, Esq. Sec. R. Soc. about 1749. Communicated to A. B. Lambert, Esq. F. R. S. V.P.L.S. by John Hawkins, Esq. of Dorchester.'

It seems that the modern Peruvian bark, though called quina-quina, is not produced froin the tree of that name. The bark of the quina-quina was that which was first imported; but it was superseded by the bark of Loxa.

XIV. Natural History of Perca Scandens. By Lieutenant Daldorff, of Tranquebar. Communicated by Sir Joseph Banks, Bart. K. B. P. R. S. H. M. L. S.'

This climbing fish is fingular. It seemingly moves like a worm, fixing its hinder part by means of its (pines, and expanding its upper parts. It was found on a tree five feet above a lake, endeavouring to climb higher.

XV. « The specific Characters of some minute Shells difcovered on the Coast of Pembrokeshire, with an Account of a new marine Animal. By John Adams, Esq. F.L. S.'

These specific characters are incapable of abridgment. The animal appears to be a new genus of the vermes zoophyta : it is styled derris fanguinea.

XVI. On the Latin Terms used in Natural History. By the Rev. John Brand, A.M. A. L. S.'

This is an ingenious defence of the new language of natural history, from the practice of the ancients, supported by the authority of Cicero.

XVII. Additional Observations on the British Species of Carex. By the Rev. Samuel Goodenough, LL. D. F. R. S. T. L. S.?

be styled the gleanings of the researches which occurred in the second volume of the Transactions.

XVIII. · A Description of the Porbeagle Shark, the Squalus Cornubicus of Gmelin, Var. a. By the Rev, Samuel Goodenough, LL.D. &c.'

ivir. Pennant did not see this species. It seems to be accurately described; but fome doubts of its identity with the squalus Cornubicus may arise.

XIX. - Oblervations on the British Fuci, with particular Defcriptions of each Species. By the Rey. Samuel Good

These may

enough, LL. D. &c. and Thomas Jenkinson. Woodward, Esq. LL. B. F.L.S.'

The present ellay would, of itself, form a volume. The writers particularly describe seventy-two fuci, with fome important botanical distinctions. The account of the places in which they are found, the variation of forms, and other particulars, are correctly stated. The paper terminates with these reinarks :

• Whatever we have faid in this tract, we again beg may be brought to the test of the closest examination. Particularly we with that gentlemen of science resorting to the sea-side, and especially those who are resident on it, would omit no opportunity of examining the growth of marine plants, their various appearances, and the progress of the parts of fructification. We are confident of nothing, but that we have stated what we have actually seen. In a subject fo intricate as this, it would be highly advisable that all prejudices, and all comparisons and ideas of analogy taken from plants growing on land, should be entirely laid aside. This formness of thinking led to a better illustration of the natural orders of the genera, by the indefatigable Jullieu ; to a deeper investigation of the nature and properties of the seed, by the celebrated Gaertner; and of the mosses, by the illustrious Hedwig. Why should it be thought impossible, that the submarine plants, like the animals of that elernent, should have powers and properties new, original, and peculiar to themselves ? The power of God is over all his works, and is seen, to the astonishment of man, in the variety of his wonders. But what can equal the satisfaction which he must feel, to whose patient and unwearied observation the discovery of this hitherto latent process shall be made manifest? What labour would not be well repaid by the discovery of another chain of reasoning, leading us to a farther confirmation of the existence and operations of the eternal Godhead?'

P. 235: XX. Description of Ulva Punctata. By John Stackhouse, Esq. F. L. S.

It is doubtful whether this plant should be reckoned among the ulvæ or the fuci.

XXI. • Observations on the Genus of Porella, and the Phascum Caulefcens of Linnæus. By Mr. Jarnes Dickson, F. L: S.'

This genus was established by Dillenius; but his porella appeared to Mr. Dickson, on examination, to be a jungermannia. The splachnum was considered as a phafcum by Linnæus, though without fufficient reason.

XXII. . Description of the Ribes Spicatum. By Mr. Edward Robson, A. L.S.' This article is of little importance in any view, and might

have been omitted without injury to the credit of the collect tion.

XXIII. Observations on the Infects that infested the Corn in the Year 1795. In a Letter to the Rev. Samuel Good, enough, LL.D. F.R. S. Tr. L. S. By Thomas Marshan, Esq. Sec. L. Si

The late-fown wheat was chiefly subject to the depredations of these insects, which, however, did not materially injure the grain, but confined themselves to the hulk. They were concealed by an orange-coloured powder, which the farmers called the xed gum,' and which seemed to be the farina of a small lycoperdon. The grain was therefore originally diseased ; and this lycoperdon was the nidus and food of the insect. The thrips phyfapus, and a minute paralitic ichneumon, were found in the diseased ears.

is unimportant. XXV. Botanical Characters of fome Plants of the Natural Order of Myrti. By James Edward Smith, M. D. F.R. S. P. L. S.?

The natural order of the myrtles is not clearly defined or understood. We shall therefore subjoin the president's cor. rected description.

• These plants agree in having an arborescent stem, the wood of which is generally hard, and of low growth. Their leaves are simple, for the most part entire, and evergreen ; often dotted with clear refinous fprats, and alniost always more or less aromatic, sometimes aftringent. Calyx monophyllous, urceolate, or tubular, with Yeveral, generally five, teeth, the body of the calyx being permanent, and investing the fruit (in some instances pulpy), though the teeth are very frequently deciduous. Petals equal in number to the teeth of the calyx, alternate with them, and inserted into the rim just within them. Stamina inserted into the fame rim within the petals, numerous, rarely only equal to the petals in number, or about twice as many; for the most part very long, but, in some instances, shorter than the corolla. Germen in the bottom of the çalyx, fimple. Style one. Stigma undivided. Fruit either a berry or capsule, formed of the body of the calyx, or invested with it, consisting of one or more cells, each cell containing one or more seeds.

White is the prevailing colour of the flowers. I know no instance of an inclination to blue.'

P. 255: He afterwards particularises many species, belonging to imbricaria and eight other genera. The paper is a very cor : rect and fatisfactory morceau of botanical criticism.

XXVI. Obfervations on the Genus æftrus. By Mr. Bracy Ciark, Veterinary Surgeon, and F.L.S.

These observations are new and curious; and a scientific description of each fpecies, with the fyncnyms, is fubjoined. The æftrus bovis has been overlooked, or confounded with the c. equi. It is, however, a distinct species; and the larva buries itself in the backs of oxen, forming an abicess, in which it lives till it becomes a chrysalis, feeding seemingly on the purulent matter. This animal, being litrie known, is defcribed at length. The apparatus of air vessels is extensive and highly curious. It is found in all the æftri, and in most other insects. In those which are exposed to fo warm a temperature, it cannot be for the purpose of keeping up a given heat in the animal. As the system of air veffels is much less in the perfect insect, Mr. Clark suspects that its chief use is in digesting and assimilating the food; for the fly eats littie, and often nothing. To this opinion, however, we cannot affent ; and we rather consider this apparatus as designed to collect a supply of air or Tone other neceffary for the future state of the infect. The noise of the fly is sharp, and eally hcard by the oxen. It throws them into violent agitations, and they run off with tlfe most activerexertions to the water, hursying along with then the plough or any carriage to which they may be fastened. The centrus injures the hide by its numerous perforations ; for it is known that the skin is never re-produced ; and, in general, the most healthy animal is fixed on by the parent fy for the nidus of its young.

The æstrus equi gives birth to the larvæ which reside in the horse's stomach. Mr. Ciark thinks that these are not so injurious as they have been supposed. All the larvæ inhabit-ing the internal parts of the body, and the mucous membranes, are furnished with hooks or tentacula : thote which infest the skin have none.

The citrus hæmorrhoidalis is found in the rectum; but the eggs are deposited on the lips and swallowed. The larva arrives at its perfect state, when it has, in a gradual progress, reached the part where it is found. The æ. veterinus (nafalis L.) seems, in our author's opinion, to inhabit the fromach; but he is less acquainted with it than with the other fpecies.

The ce. ovis is found in the maxillary and frontal sinuses, and discharged through the nose; the egg seems to be deposited on the inner margin of the nostril, and the young animal to pass into the finus.

Some directions are added for preventing the attacks of the fly, drawn froin the economy and habits of the animal; but Mr. Clark is inclined to believe, that these irritations may be of service, and prevent glanders, farcy, and other disorders of cattle.

XXVII. Characters of a new Genus of Plants named Salisburia. By James Edward Smith, M. D. F. R. S. P. L. S.'

This article, and the extracts from the minute-book, offer nothing very interesting.

The Infiuence of local Attachment with respect to Home, &

Poem, in seven Books: a new Edition, with large Additions : and Odes, with other Poerns. By Mr. Polwhele. 2. Vols. 8vo. 85. Boards. Johnson. 1798.

THIS interesting poem, which we noticed with approbation on its anonymous appearance *,

*, has now received considerable alterations, and is, in our opinion, much improved. The tale of Ellen and Danvert is judiciously separated from the poem : the arrangement of the whole is better ; and many beautiful parts have been added. We extract one of those passages from which we derived most pleasure.

• How wearisome “ the race my feet have run,"

Since on this green I gather'd infant flowers !
Ah ! little dream'd I, when life's morn begun,

That I should pass my exile-faddening hours,

Where pale amidit her cloud affliction lours ;
Where sickness gives to bitter tears the night :

Yet, distant from Polwhele's deserted bowers,
Hath forrow, tainting the purpureal light,
Render'd those prospects dim, which once were lovely:

bright.
Each object by a few short years how chang'd ;

The hall, where once we hail'd the cheerful blaze;
The chairs in social order oncé arrangd;

Those mouldering pannels where we usd to gaze,

On the light shadework that in many a maze
Danc'd to the foliage of yon falling elm,

While evening ting'd its boughs with saffron rays;
Those portraits, where the golden-pictur'd helm-
The hauberks' mimic steel, dark webs and duft o'erwhelm.
And, as the parlour-hinges harshly grate,
The torn prints flutter but the type of

ine,-
Where once fo warm each crimson-gleaming seat,

And once lo rich appeard the soft settee ;

Where, the flower'd carpet as I trod with glee,
The mirror would reflect my frolic smile :

Where from yon screen, once wrought in filligree
