An ExtraB of a Letter^ relating an Experiment f^ade for 
altering the Colour of the Chyle in the LaUeal Veins ^ by 
Martin Lifter E%. 
THe paflage of the Chyle through the Inteftines in- 
to the Lafteal Veins, is a thing hitherto demon- 
ftrated to the Eye by none. Dr. Lower ingcnioufly con- 
fefleth the ill fuccefi he had in trying with Aer, or with 
tinged Spirit of Wine 5 by neither of which he was able 
to fdrce a paffage. And J.Walaus (Epiji.de motuChylt) 
is very pofitive, that however the Chyle in the Inteftines 
may be diverfly coloured 5 yet it is ftill white in the 
Lafteal Veins. And Diemerbrodk in his^ late Anatomy
