the neutral fait made with the acid obtained from 
this fubHance by diHillation. 
In order to procure this acid, I prevailed with 
Mr. Winter, brother-in-law to Mr. Heineken, 
apothecary, to diftil four or five pounds of honey 
in a retort ; at fir ft he imagined that I only wanted 
the watry phlegm, which has been called by the 
name of the fpirit of honey, and flopped the riiftil- 
lation before the acid came over; but having di- 
Hilled a fecond quantity, he procured me about fix 
ounces of a very acid liquor, which I mixed with 
the phlegm or fpirit which he firfl brought me; I 
then faturated the whole with the foflil alkali, fil- 
tered and evaporated the liquor to a pellicle. After 
it had flood all night in a cool place, I found the 
pellicle to be compofed of a yellow, bitter, faltifh, 
mucous and oily matter ; below which was a dark 
purplifh liquor, which I poured into a tea cup, and 
there remained at the bottom of the flonegallypot, in 
which the evaporation had been performed, a yellow 
concreted matter, fomewhat of the appearance of 
yellow wax, mixed with a little honey; on the fur- 
face of which was to be obferved a number of glo- 
bules of the fame fort of matter, of the fize of mil- 
liard feeds; and interfperfed with a black very bitter 
fluff. Next day, on examining the dark coloured 
purplifh liquor which I had put into the tea cup, I 
found that a great part of it had concreted into a 
very beautiful fait, which is reprefented by fig. 20.
