Experiment h 
Icaufeda Dog to be fed, and after four hours, or 
thereabout 5 and having ready by me a clear Tin^ure 
of Indigo, diOblved in fair Water and filtred, I opened 
the Ahdomenymd making a ftnall InciGon in the Jejunum^ 
I injefted an ounce or two. This done, we ftitch'd up 
the Gut, and all, again, and the Dog turned upon his 
Leggs. After one hour and a quarter, we cut theftichr 
cs 5 and then beheld a copious Diftribution of Chyle and 
turgid LaSed Feins 3 but as white as ever. And yet 
carefully fearching the Guts, we perceived none of the 
Injedted Liquor any where. 
Exper.lh 
Another Dog, which was kept fafting 40 hours, bad 
a very little fleih, without water, given him, about 5 
hours before the Injeftion of the Tinftureof Indigo 
which was performed after the lame manner, as before : 
only it was now well warmed, and about Twelve Oun» 
ces thrown up the D«^<^e««;», and down the Ikon. Here 
were empty Guts, and not the leaft appearance of any 
La&eal Veins in the Mefentery. After full 3 hours , the 
Stiches were cut again ffome bufinefi hind ring me 
from doing of it fooner) and carefully examining the 
Mefenterj^ we found many La&eal Vans of an Azure 
Colour 5 and cutting fome of thebigeft of them afunder, 
we plainly faw a thick blewifli Chyle to iflue forth, and 
to fprcad it ftlf over the tran(parent Membranes of the 
Mefentery^ This is a very truth, which the Chirurgeon 
I employed to affift me, in the Experiment, can well 
witnefs , whole Eyes I ufcd, as well as my own, in care- 
fully examining thefe matters. 
Whence, although it hath been doubted of by fome, 
yet is it moft evident. That the LaBeal Veins receive, 
what they carry ^ from within the Gavity of the Intefi- 
ines.
