for discussion in the lecture-room. I shall, therefore, merely mention by way of exciting attention to some of the phænomena alluded to, that it seems impossible to account for those which Mr. Hunter conconsidered as the effect of sympathies between remote organs, or for those consequences of idiosyncrasy which have been mentioned, upon any other supposition than that of a subtile substance, prone to act, or liable to fail in action, pervading the body, the affections of which can with electrical celerity be propagated throughout the system.

I have further to shew that Mr. Hunter's Theory of Life is adequate to explain the cause of the prevention of putrefaction, and the regulation of temperature. If the vital principle of Mr. Hunter be not electricity, at least we have reason to believe it is of a similar nature, and has the power of regulating electrical

operations. That electricity is the great chemist both in organized and unorganized bodies, will be generally credited ; and that the power which combines may also prevent decomposition is too obvious to need discussion. That electricity is capable of augmenting and diminishing the temperature of unorganized 'matter is well known. Does not Platina wire drop like wax in fusion when it intervenes between the different ends of the voltaic battery? and do not the spherules of rain fall to the ground at midsummer as firmly frozen as in the depth of winter, when they pass through a stratum of air refrigerated by electrical operations? I believe I need say no more on these subjects.

The varying and the strong retention of life by seeds, and some kinds of vegetables and animals, are facts which seem

more satisfactorily solved by Mr. Hunter's Theory of Life than by any other.

Impressed with the difficulties of the task I have undertaken, of giving lectures in the presence of men of superior knowledge and talents, respecting subjects on which every one has formed his own opinions, which of course he thinks correct; though desirous of fulfilling the design of these lectures to the extent of my ability, I feel unable to display the subjects of them in any other way than that to which I have been accustomed. Thinking as Mr. Hunter taught, with regard to life and its functions, in health and disorder, I must use his language as expressive of the phænomena we observe. That an attention to the sympathies of parts and organs is necessary to our understanding disorder and disease, I shall hereafter endeavour to shew. That Mr. Hunter
