blood, within the space of half an hour, at several arteries. — ^The ribs of a dog 

 were found more brittle near that end by which they are joined to the vertebrse 

 than at the other end. — A needle being driven into the brain of a dog, between 

 the first vertebrae and the os occipitis, the dog seemed as if struck with an epi- 

 lepsy, and died in a little time. — The passage from the pelvis into the ureter 

 of a dog being stopped, the kidney of the opposite side was found larger than 

 ordinary. — Six veins being tied in a dog, viz the two crurales, the two axillares, 

 and the external jugulars, the dog seemed choked in a very little time; the 

 ligatures being loosened, and blood drawn, the beast moved again. — A proci- 

 dentia ani has been caused in a dog to the length of a foot. A dog not much 

 troubled at the pricking of the meninges, was concerned when the spinal mar- 

 row was pierced. Experiments have been tried by the author, with tallow in- 

 jected into the veins of dogs. — The venae mammariae have been observed to 

 communicate with the epigastricae in a bitch ; for blood was easily pressed from 

 the former into the latter, and back again, — A phial which, when filled, con- 

 tained 1 lb. of rain water, held l lb. and 1 oz. of venous blood, of arterious 

 blood, and of serum, taken promiscuously from both sorts of blood; but it 

 held 1 lb. 1 oz. and ^ of grumous blood, cleared of the serum. — The author 

 affirms that no lacteals arise either from the stomach or intestina crassa. — Valves 

 are observed in the farther part of the ductus thoracicus, near its ending in the 

 subclavian vein, contrary to what is affirmed by some anatomists. — The valves, 

 lying in pairs in the ductus thoracicus, are generally an inch and half one pair 

 from another. One kidney has been found 8 times larger and heavier in a dog 

 than the other. — The author asserts that the lacteals impart no liquor to the 

 pancreas asellii. Their origin has been traced as far as the glandulous tunic of 

 the intestines. 



There are several other observations concerning the lacteals, the ductus tho- 

 racicus, and the valve at the end of it. There follow also several queries de • 

 semine virili, de foemineis ovis, vel in ovario, vel extra de utero ; to which are 

 subjoined some corollaries concerning the human foetus, which he will not allow 

 to have an allantois, or urachus. 



in the highest terms of admiration and respect. He was much devoted to the ancient writers and 

 maintained that Hippocrates was acquainted with the circulation of the blood, and that the small pox 

 is not a disease of modern times. He bestowed some pains upon comparative as well as human ana- 

 tomy, having dissected various quadrupeds, of which an account is inserted in Blaise's Anatome Ani- 

 malium. Dr. Drelincourt died in l697. He was a profound scholar, and was particularly well versed 

 in the Greek; but Haller, not without reason, criticises his latinity as turgid and metaphorical. He 

 wrote with much acrimony against his contemporary Sylvius, and evinced a great contempt for the 

 chemical sect of his days.
