A few days after this, repeating the Experiment in a- 
nother Company, with thQ ^olmion oi Stone Blm in 
Fountain water, and on a Dog that had been kept faft- 
ing 56 hours 5 I faw feveral of theXadeals become of 
a perfect Blue colour, within very few Minotes after the 
Injeftion : For they appeared fo, before I could fo w up 
the Gut. 
About the beginning oi March following, having kept 
a Spaniel fafting 36 hours, and then Syringing a pint 
of a deep Dcco£tion of Stom Blue with common Water 
into one of the fraall Guts and after three hours, open* 
ing the Dog again, I faw many of the Ladeals of a deep 
Blue Colour. Several of them were Cut, and afforded a 
Blue Liquor^ (fome of the Decoftion,) running forth on 
the Mefentery. After this I exarain'd the DmBus Jhora^^ 
cicm^ ( on whichj together with other Veffels near it, i 
had, upon ray F\.eturn, made a Ligature ) and faw the 
Reraptaculum Chyli^ and that Du^iuSj of a Bluipj Colour 5 
not fo Blue, indeed, as the Lafteals, from the Solution 
mixing, in and near the Receptaeulum^ with hymphax^ 
but much Bluer than the D//^^ ufes to be,' or than the 
Lymphatics under the Liver fwith which I compared it) 
were. 
I trufted not my own Eyes in any one of thefe Expe- 
riments 5 but in each of them had the Company and Af- 
fiftance of fei^eral Phyficians ^ who all agreed with me, 
as to the Colouring of the Lafteals.a 
I (hould not have infifted thus minutely on thefe Ex- 
p'erimenrs, were I not convinced they do right to a Learn* 
ed Man, (whofe fuccefs in tinging the Lafteals is unde- 
fervedly queftiooedj and alfo eftablifbed a propofition 
of extraordinary confequence,both in the regular and di- 
fturbed Oeconomy. For 
The entrance into the Lafteals (which is much the 
narroweft part of all the way^from the Mouth to the 
Mafs of Blood) being thus beyond exception, proved 
wide
