The Anatomy <?/ <2 H O R S E . \ti 



The Chyle being thus prepar'd in the Stomach, pafies 

 by Degrees out at its lower Orilice into the finall Guts, and 

 is by the fame Powers fqueez'd into the fmall and minute 

 Orifices of the /^t?!?^/ or milky Veins ; which, as has been 

 obferved in another Place, arife from all Parts of the 

 faid Guts, by fine capillary y or Hair-like j. p n- 

 Tubes : And altho' thefe Tubes are fo fmall ^y^^ fmaUQuts 

 that they cannot be perceiv'd but in Animals 

 open'd alive immediately after Eating, at which Time they 

 are full of Chyle ; yet every one of them imbibe and drink 

 up Part of the refined Aliment ; and as they run from the 

 Sides of the Gats to the Glands in the Mefentery, they unite 

 and form larger Branches, and are call'd the laHeal VeJJeh 

 of the firft Kind. Thefe Extremities of the La/fea/s hav- 

 ing Communication with the fmall capillary Arteries of the 

 Guts, receive a thin Lymphdy which not only dilutes the 

 Chyle, and helps to drive it forwards, but alfo walhes the 

 Laheali and Kernels^ that they may not furr and be Hop- 

 ped up by its ftaying in them upon falling. 



There are other La^eals^ which are larger, q-j^^ LaSlcals 

 and are called Vena La^e<ff Jeciindi generis^ 

 or the Ladteals of the fecond Kind : Thefe receive the 

 Chyle that was difcharged by the firft^ into the veficular 

 Kernels of the Mefentery, and carry it immediately into 

 its common Receptacle. 



The Lymplonticki^ which arife from mod of the In- 

 teftines of the Lower Belly, and from the lower extreme 

 Parts, empty their Liquor into that Receptacle, which 

 being mixed with it, makes its Parts Hill more fine, and 

 fit to be united with the Blood ; and as the Chyle leaves 

 its Receptacle, and afcends the I'horaick Dud, the other 

 Lymphaticks, which arife from the Parts contain'd in the 

 Cheft, empty themfelves into the Dudl, and thofe which 

 come from the Head, Neck, and Arm?, difcharge their 

 Contents into the Jugular and Subclavian Veins, by which 

 it becomes yet more diluted and perfcdt, as it entera into 

 the Mafs of Blood. 



The La6teals and Thoraick Dufl have 7^<? Thoraich 

 Valves, which open for the Paflage of the ^'^^ '^^'^ ^^^°
