on and life: In a word, by exciting that Principle of continu- 
al Motion, which, whilft it has ftrength enough, ftill fubdues and 
gathers to its felf whatever is proper to entertain it , and ie- 
?efts what is not fo. But fuch an Invention as this he fees caufe 
to efteem very difficult, in regard that different Moulds «n- 
not but Charadterize things differently. Hence he proceeds to 
the Examples, wherein Trans fit [ton hath been expel imente , 
even upoii Men 5 alledged in that known ingenious L^ttei 0 
Monfieur Denys. And here he intimates , how much he was 
plea fed to learn, that, according to his Con je&ure , a Moderate 
Intromiffion of Blood had well fucceeded , and the Fermentation q 
which he forefaw would be caufed by the commixture of two 
Bloods , was made with advantage to the Patient: VVhich lie 
judgls did manifeftly appear by his Bleeding at the Note, '

by this, that an expert Acquaintance of his, transfufing a great, 
quantity of Blood into feveral Doggs, obferved alwayes , that 
the Receiving Doggs pified Blood. , _ : 
And as to the other fuccefsful Experiment, _ 
healthy and robuft man, he notes, that he being a lufty Fellow, 
ftored with blood, and taking the Air, and working hard on the 
fame day that the tryal was made upon him, his vigorous Bxoo , 
Spirits, and Confiitution, and the ftrong motion ol his Heart, 
were able to convert into the fubftance of his own Blood that 
of the Lamb received , and to impart thereto its own nature , 
and to mould it into Figures futable to the pores where it was to 
pafs, and proper to the functions it was to performe. 
But to thefe Refledlions he fubjoyns two other Inftanc.es -y of 
an unlike fuccefs 5 whereof the one is afforded by a 1 he 
other by a Dogg. As to the Man? it ought to be related before- 
hand, to prevent wonder or mifeonftruftion, that his Inteihns, 
when he was opened after death, were found to be gangren d, anci 
confequently , that then he appeared to have been a fubjeCt al- 
together unfit for this Experiment , feeing it was naturally mi- 
■ poffible for him to live with fuch a putrefadion. But to come to 
the tryal it felf*, this Author faith, that Baron Rond, Son to t ie
