work To laborious to his whole body that it might almoft tire a 
horfej thus hcfpent all the afternoon, and fo kept us from ma- 
king fuch obfervations upon him as we had intended, I met 
him the next day in the Itreets, and undemanding from him- 
felf this behaviour, I was furprifed at it , and blam d him of 
imprudence. But he told me in excufe of himfelf, th at he could 
not be atreft when he was in health, that he had felt no pain 
either during or after the operation, that he had eaten, drank 
and flept very well, that he had more ftrength than before, that 
if we were minded to repeat the fame experiment at any time, 
he defired we would choofe no other perfon for it but him. Sc 
that another time he would lie down to reft, and pun&uaily 
behave himfelf as we fhould command him. 
This is an account of ourExperiments 3 which indeed have not 
yet proceeded very farj neverthelefs I could not longer con- 
eeale them from your curiofity, knowing well that from thefe 
few obfervations you wdl forfee conferences and advantages 
enough. I have not deferibed the manner of our making this 
Experiment upon man 5 which is very different from that which 
we ufe upon beafts : but the particular relation would be but 
tedious and ufelefs to you, fiuce you will behold it more plainly 
in an example when ever you fh all find a convenience to com- 
mand us to make the fame before you. And I allure my felf^ 
you will therein admire the dexterity and fagacity of Mr. 
Emmery and confefs that his induftry renders him as happy 
in this operation as in many others of Chirurgery which are 
much more difficult, for indeed tis done with as much fpeed as 
an ordinary phlebotomy, and he that receives new blood com- 
plains not of any pain that he feels. 
But I perceive thatl abufe y^pr patience,and that the length 
of my letter hath paired the bounds wherein the refpetff I have 
for the perfon ought to confine me, I befeech you pardon me 
this liberty, and be not difpleas’d that I take this occalion to 
confecrate to you my molt humble fervice, and to allure you 
that I am.
