gives his discovery of a new gland, with its proper ductus ; his observations on 

 the saliva ; with an historical account of the ductus salivalis when disordered. 

 This gland is seated in the orbit of the eye, just between the musculus abducens 

 and the uppermost part of the os jugale; it is of no certain figure, being some- 

 times oblong, sometimes almost round or oval, and sometimes triangular ; it 

 exceeds not the size of a small nut, or the weight of 4- a drachm, or 2 scruples 

 at most ; it has 4 sorts of vessels besides that peculiar to it ; an artery from 

 the carotid; a vein from the jugular, and its nerve springs from the third pair, 

 called motorii oculorum ; and he does not question but it has lymphatics also. 

 Many small sprigs rise from this gland, which meeting together join all in one 

 duct; which, crossing the ductus stenonianus, passes directly downward on the 

 outside of the os maxillare, and opens on the last tooth but one of the dentes 

 molares of the upper jaw. Our author gives it the name of ductus salivalis 

 superior alter, in opposition to that of Steno. 



In the second part of his book he gives an account of certain ducts which 

 convey water to the eyes, having the first time accidentally hit upon one in the 

 Gadus, he traced it along on the outside of the tunica sclerotis, till it entered 

 that part of it called the cornea : it easily admitted a probe, but nothing issued 

 on withdrawing the probe, because, as he supposes, the extremity of the duct 

 serves as a valve, and discharges its matter after the same manner as the ductus 

 communis, the ureters, &c. do into their respective cavities without admitting 

 regurgitation. He has found in dogs and birds 2 in each eye, exactly opposite 

 to each other; in some sheep's eyes 5, in others 6 : but he can by no means 

 discover their rise, being able to trace them as far as the optic nerve, but very 

 little farther ; he assures us that they are also present in the human subject.

• This expert Dutch anatomist, who flourished in the 17th century, bestowed great pains on the 

 glands and lymphatic vessels. He was very successful in tracing and demonstrating the course of the 

 last- mentioned vessels by quicksilver injections. Besides the treatise above-noticed (which was several 

 times reprinted with additions under the title Sialograpbia) he wrote the following: Defensio duc- 

 tuum aquosof. 1691, and Adenographia, 1691 ; both which, with the first mentioned work, and some 

 other tracts, were republished together in 2 vols, under the title of Opera Omnia. 1733.
