PROGRESS OF THE VETERINARY ART IN ENGLAND. 27 



are told, described those two ducts, the discovery of which is 

 attributed to Fallopius, and from him are called the Fallopian 

 tubes. These* he discovered in dissecting the womb of a 

 ewe, and adds, that he strongly suspects them to be seminal 

 vessels, and of the same nature with those of the male. 

 Galen demonstrated, in Rome, on living animals, the organs 

 of sound and respiration ; he made several observations on 

 the brain of animals ; he also showed the effect produced by 

 ligature on the recurrent nerves. Vesalius proved, by experi- 

 ment on animals, that it was possible to restore suspended 

 animation, by inflating the lungs artificially, which discovery 

 has saved the lives of many individuals. Croon and Hook, 

 two English physicians, repeated the same experiments, a 

 century afterwards, and with success. Wharton, a physician 

 of London, discovered the salivary glands in an ox. 



In 1659, Eustachius was the first who found out the tho- 

 racic duct in the horse ; a hundred years afterwards, the same 

 canal was discovered in man by the immortal Harvey. Dr. 

 Wren, professor of the University of Oxford, made several 

 experiments on living animals, to be assured of the effect of 

 different substances on the blood and solid parts, the result 

 of which experiments was to confirm the discovery of Har- 

 vey, which for the space of forty years was strenuously 

 opposed. Gesner Aselius, professor of anatomy at Pavia, 

 repeated the discovery of the lacteal veins in the mesentery, 

 in brute bodies, which had formerly been known to Erasis- 

 tratus and Herophilus. Pecquet traced them to the thorax, 

 and completed his discovery by that of the thoracic duct. It 

 was in the body of brutes, also, that Bartholinus discovered 

 the vasa lymphatica. 



S tenon, a native of Copenhagen, but afterwards physician 

 to Ferdinand the Second, Grand Duke of Tuscany, discovered, 

 in 1661, the excretory ducts of the lachrymal glands in the 

 eye of a sheep. Malpighi and Bellini, in 1665, described the 

 organs of taste in quadrupeds. Observations on the organs 

 of feeling were first made on the skins of brutes, and after- 

 wards verified on the human skin. Weiff made experiments
