along his Arme, but in brief, he prefently became more cheer-

time got the victory over his drowfinefs ^ he had no longer

him. / ' 
Though Mr* D^w/V hath fufficiently afifwered the weak ob- 
je£tions againft the Pradlice of this new Art, yet, how the 
found infus'd blood of one Animal, mingling with the infe&ed 
Mafs of another (and efpecially, of a different Species,) indu- 
ceth renovation and health into the difeas'd, without receiving 
infedtion from fo defpcrate acommixtion, feems worthy of a 
further inqu'ry than has been yet made. 
As to the Experiment of the exchange of blood , between 
the Mangie Dog and the Sound one^ by which the firft receives 
his cure, the other remains uninfediied, Mr* Denis inquires 
whether the blood of the Mangie Dog were putrefied , and 
corrupted in his veins or not : As if pucrefaftion of the bloody 
were neceffarily the efficient caufeof the Difeafe j butty the 
common experience of Anatomy, the blood i« found not to 
putrefy within the rein many daies after death 5 much lefs than 
it is to be fufpedtad ordinarily of putrefacSioii in the living 
vein, where, by continual circulation , and the irrigation of 
the vital Balfome of its volatile fait, congelatien, the beginning 
©f putrefadion is mofl powerfully refitted. BefiHas, the Adepti 
know how to reftify the blood in all Fevers, tht Galienifis call 
putrid, [cithtutb & jucundf) with the precipitate Diaphoretick 
of Petracclfus 5 But furely,if putrefaction be the repulfion of the 
Crafis of the thiiig putrefied, neceffarily inducing a new form, 
the blood muft either be granted not putrefied in the Veflels , 
or a regreffion from privation to habit, which is abfurd. 
. In the fame Experiment , Mr. Denis fuppofing the blood of 
the Mangie Dog te be wholly corrupted in his veias,{maginc3 it
