When we fill that Veflel with fome liquor for the 
experiments, we pour the Liquors into the Bottle by the 
opening B, until it goes out by the little tube D, and 
if the height of the Liquor is even to the mark C, 'tis 
well 5 if it is lower, we muft fill more to that pointy 
if it is higher, wemuftftrike foftly upon the opening 
B, till the overplus of the Liquor be even to the 
point C in the neck of the Bottle.By that means we have 
always exadly the fame volume of Liquor, and we can 
know how the fame volume of the feveralLiquors weighs 
more one than another precifely, but as the volume of 
Liquors is not always the fame, and changes according 
to the alteration of the weather, now colder and then 
hotter, we muft confider the variation of the weather, 
when we will do the Experiments in feveral times, and 
when we will compare the weight , of the Liquor, 
which we weigh in Summer time, with the weight of 
an other, which we have weighed in Winter 5 for the 
fame Liquor being more rarefy'd in the hot time, and- 
condens'd in the cold, the fame volume of it will be 
more weighty in cold weather than in warmi for that 
purpofe M. Homkrg has gi ven us a Table of the va« 
rious weights ot fome moire ufual Liquors in the cold- 
eft time and in the hotteft, as it is underneath.
