and flow Bullition. Hence there is a greater proportion of 
or Oyl, andleß of an Alkaly in all thefe parts, than there is in Bones, 
Shells, and divers other parts hereafter mentioned. And in fome of 
them, as inthe Brain, that Alkaline Salt which there is, may rather be 
lodged in fome fanguincous parts mixed with them, than in their own 
proper fubftance. > 
24. $. T proceed to inftance in all forts of Animal Contents. And 
fifi, raw Silk, with Spirit of Nitre, makes avery fmall Bullition, bus 
the elevation is confiderable. 
25. $. The grumous part of the Blood dryed, with Oyl of Vitriol, 
fürs but little, But with Spirit of Nitre it buffs up confiderably. 
26. s. Serum of Blood dryed, with the fame Spirit makes a plain 
elevation, with a little Bullition. Herewith may be reckoned the White 
of an Egg, which is nothing int a pure Cryftalline Serum feparated from the 
common fock, This being dryed, with Spirit of Nitre, buffs up rather 
more than even the grumous 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 Generation, than to the Nutrition of an 
Animal, 
27. $. The Yelk of an Egg is fearce moved with spirit of Nitre, pro- 
ducing only a very few Bubbles. The Salt being either little alkalizate, 
or elfe immerféd in fo great a quantity of Oyl, that the Menfirnum can- 
not reachit. For the fame reafon Sperma Ceti Stirs not with any Acid. 
Neither doth Civet. 
28. $. Ruffian Caftor, with Oyl of Vitriol, Stirs not. But with 
Spirit of Nitre makes a confiderable huf and froth. Yet it requires time. 
Wherefore itfeemeth, That Calor by virtue of its alkaline Sulphur, 
becomes fo good a Corrector of the acid-alkaline sulphur of Opium : fo 
I take leave to call it, having fome reafons to believe it fach. E 
29. §. Musk, with Oyl of Vitriol, ftirs not. But with Spirit of 
Niire it makes a confiderable and quick Bullition, with laigo bubbles, 
which often break and rife again. Whence there is a very eminent dif. 
ference betwixt Mush and Civet. Hence alfo, Musk is Cordial, not 
only from its Sulphur, but its Alkaly 3 by both direGtly Qppofite to pre- 
ternatural Acidities. 
30. $. Dryed Gall with Spirit of Nitre, for fome time, is fil > but 
at length it makes a confiderable Bullition and froth, The reafon why 
it is fo Jong before it begins, is becaufe the salt, (as was obferved of 
fome other Parts ) is locked up in fo great a quantity of Oyl. The 
abundance whereof is manifeft, not only from Deftillation, but alfo 
from hence, In that the dryed Powder, in lying by, incorporateth all 
together into one bod h, and fome other fofter and oily Gums 
are ufed to do. 
31. $. Extra of Urine, with spirit of Nitre, makes a Bullition 
with fome Efervefience, which continues for a confiderable time ; and at 
lafi it buffs up with great bubbles. The Bullition begins prefently : the 
little.
