A certain Phifittan having told me that feveral people 
aflifted with Jgues , had been cured thereof by the ufe 
of Sal volatile oleofum » which had attenuated and rarified 
their blood- Irefolved to make what obfervatious Icould, 
of the mixture of that with Blood. And therefore 
pricking my finger mthzneedk^l put the firft time two 
parts of Blood to omoisalt*, a fecond time equal parts of 
each* The blood tmr\tA immediately of a more lively red 
color , as blood ufually does when mixed with fair Wa- 
ter f for I am of the Opinion that when blood running from 
a Vein is of a dark-red orblackifti colour, thereafonof

in the blood by Sal Volatile Oleofum, The parts of that blood 
tha t lay neareft the Salt^ changed colour firft, and by de- 
grees thofe further diftant. But taking my Microfcope to 
obferve it 3 I found thQ Bipod Globules each to be diflblv*d[ 
into Six difklnd Globules. 
ithen took Four parts of ^^//^&c. and one of and 
viewing it as quick aslcouldwithmyglafs I found fome 
of the Blood Globules much diminilhed in i of a minute ;^ 
but in i of aminute they were whaUydiflblved* Ifew
