Way to conveigh any liquid thing icomediately into the 
Mafs ofBiood 5 videl i By making Ligatures on the Vcines , 
and then opening thcm on the fide of the Ligature towards 
the Heart, and by putting into them flcnder Syringes or 
Qiiills , fattened to Bladders ( in the manner of Glyftcr- 
pipes ) containing the maitcrtobe injefted 5, performing 
that Operation upon pretty big and lean doggs^that the Vef: 
fels might be large enough and eafiiy acceffible.
