Parts of Animals mixed Lea. IL 






































































































and flow Bullition. ence there is a greater proportion of Sulphur 
or Oyl, and lefs of az Alkaly ix all thefe parts, than there is in Bones, 
Shells, and divers other parts hereafter mentioned. And in fome of 
them, asinthe Braz, that alkaline Salt which there is, may rather be 
lodged in fome famguineous parts mixed with them, than in their own 
proper fubftance. 
24. §. I proceed to inftance in all forts of Animal Contents. 4nd 
firft, ram Silk, with Spirit of Nitre, makes avery {wall Bullition, but 
the elewation is confiderable. 
25. §. The grumous pat of the Blood dryed, with Oyl of Vitriol, 
flirs but little, But with Spirit of Nitre it huffs up confiderably, 
26. §. Seram of Blood dryed, with the fame Spirit makes a plain 
elevation, with a little Bullition. Herewith may be reckoned the White 
of ax Ege, which is nothing tut a pureCryftalline Serum feparated from the 
common flock, This being dryed, with Spirit of Nitre, huffs up rather 
more than even the erumows part of the Blood, the Bubbles are much larger, 
break oftner, and the elevation fooner made. Whence it feemeth, that 
there isa greater quantity of a volatile Alkaly in proportion to the 
Sulphur, requifite to the Geveration, than to the Nutrition of an 
Animal, 
27. §. The Yelk of an Egg is fcarce moved with spirit of Nitre, pro- 
ducing only avery few Bubbles. The Salt being either little alkalizate, 
or elfe szemerfed in fo great a quantity of Oyl, that the AMenffraum can- 
not reachit. For the fame reafow Sperma Ceti Stirs not with any Acid. 
Neither doth Civet. 
28, §. Ruffian Caftor, with Oyl of Vitriol, Sirs not. But with 
Spirit of Nitre makes aconfiderable huff and froth. Yet it requires time. 
Wherefore it eemeth, That Ca(or by virtue of its alkaline Sulphur, 
becomes fo good a Correéfor of the acid-alkaline sulphur of Opium : fo 
I take leave to call it, having ome reafons to believe it fuch. 
29. § Musk, with Oj] of Vitriol, ftirs not. But with Spirit of 
Nitre it males a confiderable and quik Bullition, with large bubbles, 
which oftcn break ard rife again. Whence there isa very eminent dif- 
ference betwixt Mush and Civet. Hence alfo, Musk is Cordial, not 
only from its Sulphur, but its Alkaly 5 by both dire@ly oppofite to pre- 
ternatural Acédities. 
30. §. Dryed Gall with Spirit of Nitre, for fome time, is full : but 
at length it makes a confiderable Bullition and froth. The reafon why 
it is fo long before it begins, is becaufe the Salt, (as was obferved of 
{ome other Parts ) is locked up in fo great a quantity of Oyl. The 
abundance whereof is manifeft, not only from Deffillation, but alfo 
from hence, In that the dryed Powder, in lying by, incorporateth all 
together into one body, as Mirrh, and fome other fofter and oily Gums 
are ufed to do. 
31. §. Extra® of Urine, with spirit of Nitre, makes a Bulition 
with fome Efftrvefcence, which continues for a confiderable time 5 and at 
lft it kugfs up with great bublles. The Bullition begins prefently: the 
Salt being copious, and the Oyl but little, 
32. $. The Jame Extra of Orine makes a confiderable Bullition and 
froth, not only with Spirit of Nitre, Lut even with Oyl of Vitricl. Hence 
the Salt of Orine is more alkalive than that in molt of the afore-faid 
Contents.
