the joints and fresh bones ; Soemmering and Monro 

 on the brain*; Porterfield, Haller, Zinn, andWris- 

 berg, on then/e; Cotiinnius, Meckel, jun.. Camper, 

 Scarpa f, and many others, on the ear. Walter is 

 celebrated for his description of the veins of the 

 head and neck, as well as very elegant plates of the 

 7ierves of the thorax and abdomen. Trew has ably 

 treated of the differences between the feet at and 

 adult vessels: Dr. Monro, jun., on the Bursa Mu- 

 cosa, &c. 



The anatomists of the eighteenth century have 

 effected great improvements in the science, and 

 facilitated the communication of it to students, by 

 the number and correctness of their engravings. 

 Figures of the bones, in folio, have been published 

 by Cheselden, Albinus, Sue, and Trew, The muscks 



* Mr. Soemmering thinks it probable that tlie soul is seated in 

 the fluid of the ventricles of the brain. He infers this from the 

 fact of tlie nerves of vision, hearing, taste, and smell, being all at 

 their origin in contact with and exposed to the action of tlie fluid 

 in the ^ entricles ; from the same taking place \^'ith regard to the 

 nerv-es of touch, originating from the fifth pair, the glosso-pharyn- 

 geal, those belonging to the organ of voice and the motions of the 

 eyes ; from tlie impossibility of finding a solid part of the brain 

 into which the terminations of all tlie nerves can be traced j from the 

 nerves of the finest senses~-v22. hearing and seeing — being most 

 extensively expanded and most directly in contact with this fluid ; 

 irom the preternatural increase of tliis fluid in the ven Uncles ot 

 ricketty children, which perhaps may be the cause of their micom- 

 Fnon acuteness of mind ; and, finally, from the fact, that no 

 animal possesses so capacious and so perfectly organised ventricles 

 as man, — they being in the other mammalia much smaller than in 

 man, still less in birds, least of all in fishes, and abiolutelj 

 wanting in insects. 



t This great anatomist wrote ably, not only on the car, but also 

 on the nerves of the heart. His work oil tliis subject is said to bt 

 highly meritorious.
