anatomist will chiefly rest. His paper on the Physiology of the 

 Stapes, published in the volume for 1805, affords a good example 

 of the application of Comparative Anatomy to the elucidation of a 

 difiicult physiological question ; almost all the facts contained in it 

 relating to the form and structure of the stapes in various animals 

 were new. The Comparative Anatomy and Physiology of the Organ 

 of Hearing formed the subject of his Lectures at the College of Sur- 

 geons in 1818. 



His Lectures on Extra- vascular Substances, also delivered at the 

 College of Surgeons, but of which an abstract only of a small por- 

 tion was published in the ' Annals of Philosophy,' are alluded to in 

 high terms by Mr. Lawrence. In 1820, and again in 1826, he de- 

 livered the Hunterian Orations at the College. The latter of these, 

 containing the Anatomy of the Oyster, has been quoted in reference 

 to the observations which indicate the sensibility of the Oyster to 

 light. He also spent much time in experiments on the growth and 

 reparation of Shell. In the prosecution of his various inquiries he 

 enriched the Museum of the College wdth some unique examples of 

 his peculiar anatomical skill. 



Besides these contributions to Comparative Anatomy and Animal 

 Physiology, Mr. Carlisle communicated to the Horticultural Society 

 a memoir ' On the connection between the Leaves and Fruit of 

 "\''egetables, with other Physiological Observations,' and another 

 paper published in the 2nd volume of the Transactions of that So- 

 ciety.

The Rev. Thomas Rackett, M.A., F.R.S., 8(C., during a long life 

 successfully cultivated various branches of Natural Science and the 

 liberal arts. Associated in his school-days with Hatchett, and after- 

 wards with Maton, Pulteney and Cavallo, he became attached to 

 the pursuits by which his friends were distinguished, and assisted 

 warmly in the promotion of their views. In the years 1794 and 

 1796, he accompanied the two former in the tours which Dr. Maton 

 subsequently published under the title of ' Observations relative 

 chiefly to the Natural History, Picturesque Scenery, and Antiquities 

 of the Western Counties of England,' and furnished with his pencil 

 the embellishments of that work, which was inscribed to him in a 

 friendly and grateful dedication. In conjunction with Dr. Maton, 

 he published in the 7 th volume of our Transactions 'An Historical
