Salivare Exterius, passing from the Parotides (or the two chief Arteries that are on the right and left side neer the Throat) into the Mouth and conveying the Spittle; Where he also gives an account of several other Vessels and Glanduls, some about the Lips; others under the Tongue; others in the Pallate, &c. To which he adds the Vessels of the Eye-lids, which have their root in the Glanduls that are about the Eyes, and serve for the shedding of Tears. He mentions also several things about the Lymphatick vessels, and is of opinion, that the knowledge thereof may be much illustrated by that kind of Glanduls that are called Conglobate,Conglobate Glanduls are called those, that do consist, as it were, of one continued substance, having an even superficies, whereof there are many in the Mesentery, and in ether places: contra distinguisht to those, that bear the name of Conglomerate Glanduls, which are made up of several small Kernels, such as the Pancreas, the Salivating Ganduls, &c. and by their true insertion into the veins; the mistake of the latter whereof, he conceives to have very much misled the Noble Ludovicus de Bills, notwithstanding his excellent method of dissection. And here he observes first, that all the Lymphatick vessels have such a commerce with the Glanduls, that none of them is found in the body, which either has not its origine from, or is inserted into a Glanduls: And then, that Glanduls are a kind of Strainer; so form'd, that whilst the Blood passes out of the Arteries into the Veins through the small Capillary vessels, the Serous parts thereof, being freed from the Sanguineous, are by vertue of the heat expell'd through fit pores into the Capilaries of the Lymphaticks; the direction of the Nerves concurring.
Of the two annex'd Epistles, the First gives an account of the dissection of two Raja’ or Skates, and relates that the Author found in the bellies of these Fishes a Haddock of 112 span long, and a Sole, a Plaise, and nine middle-sized Sea-crafishes; whereof not only the three former had their flesh, in the fishes stomack, turn'd into a fluid and the Gristles or Bones into a soft substance, but the Crafishes had their shels comminuted into very small particles, tinging here and there the Chyle near the Pylorus; which he judges to be done not so much by the heat of the Fishes stomack, as by the help of some digesting juyce. Coming to the Uterus of these Fishes, he takes occasion to examine, with what ground several famous Naturalists and Anatomists have affirm'd, that Eggs are the uterus exposed or ejected out of the body of the Animal. Taking a view of their Heart, he there finds but one ventricle, and discourses of the difficulty arising from thence. As for the Lungs, he saw no clearer footsteps of them in these, than he had done in other Fishes: but within the mouth he trac'd several gaping fissures, and found the recesses of the Gills so form'd, that the Water taken in at the mouth, being let out by these dores, cannot by them re-enter, by reason of a skin, outwardly passing over every hole, and covering it. Where he intimates, that though Fishes have not true Lungs, yet they want not a Succedaneum thereto; to wit, the Gills and if water may be to Fishes, what Air is to terrestrial Animals, for Respiration: asserting, that whereas nothing is so necessary for the conservation of Animal life as a reciprocal Access and Recess of the Ambient to the sanguineous vessels, tis all one, whether that be done by receiving the Ambient within the body, or by its gentle passing by the Prominent vessels of the Gills.
The other Epistle contains some ingenious Observations, touching the way, by which the Chicken, yet in the shell, is nourish't, videl. not by the conveyance of the Yolk into the Liver by the Umbilical vessels, nor into the Stomack by the
