Page 162 - And grant, that neither the splendour of any thing that is great, nor the conceit of any thing that is good in us, may withdraw our eyes from looking upon ourselves as sinful dust and ashes ; but that...
Page xiv - The objects of the Association are, by periodical and migratory meetings, to promote intercourse between those who are cultivating science In different parts of America, to give a stronger and more general impulse and more systematic direction to scientific research, and to procure for the labors of scientific men increased facilities and a wider usefulness.
Page 98 - Hence, when individuals multiply from generation to generation, it is but a repetition of the primordial type-idea ; and the true notion of the species is not in the resulting group but in the idea or potential element which is at the basis of every individual of the group...
Page 74 - ... shore ; furnishing an illustration of the truth that the most ephemeral and perishable forms may be fossilized and preserved, contemporaneously with the decay of the most durable tissues. The rush of a single summer may be preserved with its minutest striae unharmed, when the giant pine of centuries has crumbled into mould.

Page 72 - Williamson represents a second variety, in which the transverse structure is developed in the central part of the pith, but not at the sides. In my Pictou specimen the pith has wholly disappeared, with the exception of the denser outer coating and transverse plates. All these are distinctly coniferous, and the differences that appear may be due merely to age, or more or less rapid growth. Other specimens of Sternbergia want the internal partitions, which may, however, have been removed by decay;...
Page 9 - SINCE last we met, the Destroyer has been very busy in our ranks. Besides other beloved and respected associates, our earliest and our latest Presidents have suddenly vanished from our midst; — Redfield, who was the first to suggest the idea of the American Association on its present comprehensive plan, and the first to preside over its deliberations, and Bailey who, we fondly hoped, would occupy the same distinguished position on the present occasion.
Page 123 - But — in addition to the fact that the measurements now supplied are only the more carefully noted data which have tended to confirm conclusions suggested, by previous examinations, in a less detailed manner, of a larger number of examples — an investigation of the materials which supplied the elements of earlier inductions will show that only in the case of the ancient " Toltecan" tribes did Dr Morton examine nearly so many examples ; while, in relation to what he designated the
