 variety of experiments, as cutting, prick- 

 ing, and wounding them in various ftiapes; 

 the animal all this while continuing quiet 

 and eafy, fhewing not the leaft fign of 

 pain, and when let loofe, walked about 

 perfedlly eafy : the ligaments and cap- 

 fulse of the joints he alfo affirms to be 

 equally fenfible of pain, by a variety in 

 of experiments, made by filling the ar- 

 ticulations with oil of vitriol, ^c, the 

 animals fhewing no fenfe of pain from 

 fuch acrid applications \ and thefe wounds, 

 hitherto thought fo dangerous, werecafily 

 healed with nothing but the animal's faliva, 

 often even without it. Other experiments 

 he has made on thefe parts with needles, 

 or fliarp inflruments, with the fame 

 fuccefs : in fhort, he endeavours to prove 

 the periofteum infenfibie, the diira^ pia

 like thefe, are deftitute of nervous filla- 

 ments, he fays, are void of pain ; and 

 In proportion to the quantity of them, 

 the part is more or lefs fenfible, or fub-

 experiments which fupport it, are now
