Analysis of Wines from - , Palestine, §%. 251 
Fortunately, this anticipat “Mr. Van Lennep was not re- 
ttles from Hebron contained 
considerable acetic acid, prob because in passing through so 
many custom-houses it n tested till nearly half of it was 
gone; yet even this, as v all see, contained no small share of 
alcohol. All the ot ttles, on breaking their seals, were

could J discover ‘any carbonic acid; so that probably the process 
of Semen been domploted. 
- The mode of analysis was essentially that of Mr. Brande. 
The Specific gravities were determined by ascertaining the 
be weight of a tube full of the liquor and comparing it with the 
same tube full of distilled water, in all cases at a temperature of 
60° Fah. The tube which I employed, held 736-4 grains of 
distilled water, and was suspended from one of the arms of Che- 
min’s delicate balances. The weight of the tube and liquid was 
indeed rather too great for a balance of this description, and I do 
not think I could be sure of the weight nearer than the one tenth 
of a grain, although with small quantities the one hundredth of 
a grain was perceptible. After weighing the tube full of wine, 
in order to obtain its specific gravity, it was distilled nearly to dry- 
ness, from a small retort into a receiver surrounded by snow, and 
Mierwarda, to make up for the deficiency, another small portion 
of the wine was distilled also nearly to dryness. Enough was 
thus obtained of the distilled liquor to fill the tube, which was 
then weighed and the specific gravity thence deduced. In de- 
ducing from thence the per centum of alcohol, I used the new 
tables of Tralles, founded upon the principles of those by Gilpin, 
and given by Dr. Ure in his Dictionary of the Arts, Manufactures 
and Mines. 'These tables assume thatgwater at the temperature 
of 60°, has a specific gravity of 0-9991; and they give the per 
centum of anhydrous alcohol by measure. Hence they show a 
Smaller amount of alcohol than those of Gilpin, used by Profes- 
Sors Brande and Beck, whose standard is alcohol of the specific 
gravity of 0-825. But as Gilpin’s tables have been so commonly 
used, I have added a column of the amount of alcohol by meas- 
ure, as obtained by those tables in Brande’s Chemistry. The 
tables of Lowitz of St. Petersburgh are also preferred by some. 
He assumes as his standard, alcohol of the specific gravity -796 
at 60° Fah., and gives the per centum by weight. I have given
