known. This reconcird me much to vindicate Sugar, 
which I have done formerly before the Royal Society • 
and have fhewn the unjuft Calumny of the famous Willis 
•againft Sugar, who charges it with a Corrofive Liquor, 
as bad as Aqua fortis ^ He calls it Aqua Stygia . I exa- 
min’d it, and found the Charge unjuft j That Sugar 
contain’d no worfe fubftance in it, than Milk, and Ho- 
ney, and Manna, nay even Bread itfelf. The Experi- 
ments were approv’d of, and are in your Journals; 
Some Years paft I ftiew’d Dr. Lifter the Figure that 
Sugar did naturally make, or (hoot into, and would 
have had him defcribe it, and add it to thofe curious 
Cuts of Salts before his Book of Mineral Fountains*, but 
we could not then well exprefs the Figure, which I 
have fince been able to do more accurately. For the 
difficulty lies here 3 all other Salts (hoot or cryftallize, 
and make their Figure in a cool Place 5 but Sugar will 
cryftallize only in a hot Stove, and is more apt to be 
compounded, and not to fhew its true primitive Tex- 
ture. Thus it happens to Snow, which in its true fim- 
ple fhape is an Hexagon 5 bur cannot be always dis- 
cover’d fingle. This is yet more eafy to be accounted 
for than Snow $ and we have been able to chufe fuch 
parcels of that Sugar call’d Candy, as do reprefent the 
following Figure, being a Prifm, as you may fee by the 
Figure. I never queftion’d but that it was a true Salt, 
having all the Properties of a Salt ^ and therefore made 
many unfuccefsful Experiments before my Acquaintance 
with Sugar Bakers. . I have confider’d the Virtues (and 
Vices of Sugar, if there be any) for many Years, and 
have fome few Confiderations on that fubjed 5 &c .
