ON MUSCtJLAR MOTION'. XQJ 



i'mut to digefl food; the limbs or tan(acula may be cut off, 

 and they will be regeiierated without apparent inconvenience 

 to the individual : the whole animal is equally fenfible, equally 

 irritable, equally alive: its procreation Is gemmiCerous. Every ^ 



part is pervad'cd by the nutritious juices, every part is acted ,j\ 



upon by the refpiratory influence, every part is equally capa- 

 ble of motion, and of altering its figure in all diredtions, 

 whilfl neither blood- veHe-Is, nerves, nor mufcular fibres, are 

 difcoverable by any of the modes of investigation hitherto 

 inftituted. 



from this ab(ira£l aninnal (if fuch a term may be admitted) In a-' animal' 

 ijp to the human frame, the variety of acceflbry parts, and ofis'evidenL * ^'*" 

 organs by which a complicated machinery is operated, exhibit 

 infinite marks of defign, and of accommodations to the pur- 

 pofes which fix the order of nature. 



In the more complicated animals, there are parts adapted I" ^^^ '^°''«

lor trivial conveniences, much or their materials not being n^al3 much of 



alive, and the entire offices of fome liable to be difpenfed their materials 

 with. The water lran<fu(ed throughout the interfticial fpaces^'^ "° aive, 

 of the animal fabric, the combinations with lime in bones, 

 fliells, and teeth; the horns, hoofs, fpines, hairs, feathers, 

 and cuticular coverings, are all of them, or the principal 

 parts of their fubftance, extra-vafcular, infenfible, and un- 

 aJterable by the animal functions after they are completed. I 

 have formed an opinion, grounded on exlenhve obfervation, 

 that many more p^irts of animal bodies may be confideied 

 as inanimate fubdances; even the reticular membrane itfelf 

 teems to be of this clafs, and tendons, which may be the con- 

 denfed fiate of it ; but thefe particuls^rs are foreign to the '^l 



prefent oecafjon. -r'l 



The dedu^ion now to be made, and applied to Vue hiflofyT^ that animated'^ 

 of mufcular motion, is, that a"iniated matter may be connected ^^"^^'^^^^j^j^ 

 with inanimate; this is exemplified in the adhefions of theinanimate. 

 mufcles of multi-valve, and bi-valve fliell fifh, to the in- 

 organic fliell, the cancer Bernhardus to the dead (hells of 

 other animals, and in the tranfplantation of teeth. All of 

 which, although fomewhj^t contrary to received opinion, 

 have certainly no degree of vafcu^rity, or vital conneftioq 

 with the inliabitant ; thefe (hells being liable to trajifudations < 

 of cupreous falts and other poifonous -fubflances, whilft th^- 

 animal remains uninjured.;^ A vsfiety of proofs to the (stti^t
