Mmholinum, Hafniae, 1669, in 4®. 
THis fnuU Trad being, but very lately fent Out oi Denmark^ to the 
Publiflier,he thought fit to give forthwith the following Accompt 
df it. 
Thefe two Letters ofSigneur Burrhi^iVt an Anfwer to two others, 
"^hloh^, Bartholin had written to him touching fundryconfiderable and 
curious Subjeds^of Natural Philofophy and Medicine. 
Ill the/(?r/»^r he endeavours to explain,How the 5r^/;^ is formed, and 
what kind of Subftance it i?r^In the doing of which he obfervethj That as 
many Salts, diflblved together in common water, are feycr'd by a fimple: 
Diftillation •, and as divers Mettals melted together into one maffe are 
un-mixed from one another,when a certain degree of heat is given them 
fo the different parts, whicb conftitutci the J'fW, although they be fo> 
blended together that 'tis impoffible to diftinguifli them,do dif-engage 
themfelves from one anther when they are agitated by a competent 
Heat ^ and taking the fituation which is natural to them, give rife to- 
the feveral Organs of the Body. The dired and the moft maffy, by their 
weight going to the Center, form tht Heart -, the fpongious,the Lmgs ^ 
the bituminous^ the Liver zn& tht fatty and oily, as the higheft, riling a» 
bove the reft, form the 5r &c. Where he takes notice, that Hippocrates 
holds the Brain to have little of Oylines in it .becaufe it will not flame • 
whereas he affures, that having diftilled the Brain of a Calf, he drew 
from it a confidcrablc quantity of Oyl ; which ( to note that by the by) 
being applyed outwardly, is by him recommended, as ej^cellent to af-- 
peafethe pains of the Gout, 
In the fame Letter he afErms,that in the Brain there is made a certain 
very fubtile and well- fcented liquor, which he believes to be the Seat of 
the Reafonable Soul and that the Wit of men depends on the Temper 
of this Liquor,rather than from the Conformation of the Brain: Which 
lie confirms, by the£xamplc of one,who by taking great flore oiTohacco^ 
• had.
