Philofophy, Mr. Robert Boyle, Dr. Wilkins y and other deferv® 
log Perfons , That he thought , he could ea fi-fy contrive a 
Way to conveigh any liquid thing immediately into the 
Mafs of Blood ; vhhl i By making Ligatures on the Veinei % 
and then opening them on the fide of the Ligature towards 
the Heart, and by putting into them (lender Syringes or 
Qgills 9 fattened to Bladders ( in the manner of Glytter- 
pipes) containing the matter to be inje&ed 5 performing 
that Operation upon pretty big and lean doggs,that the Veil 
fels might be large enough and eafily acceffible. 
This Propofition being made^M-Boyle foon gave order for an 
Apparatus , to put it to Experiment; wherin at (everal times, 
upon ieveral Doggs,Opium & the Infufion of Crocus Met alio- 
rum were injected into that part of the hind-legs ofthofe A. 
oimals, whence the larger Vettcls, that carry the Blood, are 
moft eafy robe taken hold of: whereof the fuccefs was 8 
that the opium , being foon circulated into the.Brain, did 
within a ihort timeftupify , though not kill the Dog 5 but a 
large Dofe of the Crocus Met allorum, made an other Dog vo

this Invention and of the fucceeding Tryals being fpread 5 
and particularly coining to the knowledge of a foreign Am-

it was by him tryed with dome Crocus Metalhmm , upon a
