a cool Celler for that purpole, yet fome ( zs^velfer ) ad- 
vife, as the beft means to have them fpeedily and fairly 
Criftallized, is to keep them conftantly in Balnea. Thus 
alfo the Ly of the blood doth bccomQ a Jelly, if you 
fet it in a cool place, and the fame is by warmth in like 
manner infpiffated ,
