estimated by a standard mercuric solution, and the-sugar-of 
milk by a standard solution of copper, or even by determin¬ 
ing the specific gravity. The author, however, prefers in 
practice the following method. A given volume of milk is 
mixed with twice its volume of alcohol of 85° (Cartier), 
which precipitates the caseine and butter together, in such 
a state that they may be estimated by measuring their 
volume in a graduated tube. The filtered solution has a 
density different from the density 09005, which would be 
that of a mixture of alcohol and pure water, and this density 
will increase by 0’094 for every hundredth of sugar-of-milk 
contained in the liquid examined. The necessary corrections 
for variations of temperature may be made by the tables 
arranged for mixtures of alcohol and water. We may de¬ 
termine in this way, with sufficient accuracy for ordinary 
cases, the amount of the principal elements contained in 
milk .—Chemical JYetvs. 
AGRICULTURAL STATISTICS OF IRELAND. 
Mr. Donnelly, the Registrar-General of Ireland, has 
just issued his annual report on agricultural statistics, which 
is full of valuable and interesting matter. We take the fol¬ 
lowing particulars from the Irish Agricultural Review , as being 
chiefly interesting to our readers : 
“The inquiries commenced on the 1st of June, and termi¬ 
nated about the middle of July; the results are very impor¬ 
tant, and exhibit among other things the effect of the great 
deficiency of the hay and other crops of 1859 on the number 
of live stock. It is, however, satisfactory to find that the 
decrease in cattle and sheep is not so great as might be ex¬ 
pected, when the extraordinary prices of hay and all feeding 
materials for farm stock is taken into account. 
“The total number of live stock in Ireland in I860 was— 
horses, 621,9*38 ; cattle, 3,599,235; sheep, 3,537,846 ; pigs, 
1,268,590. ' 
“The changes in the number of live stock between 1859 
and I860 were as under: 
“Horses in 1859,629,075; in 1860, 620,938; showing a 
decrease of 8,137. Cattle in 1859, 3,815,598; in I860, 
3,599,235; showing a decrease of 216,363. Sheep in 1859, 
3,592,804; in I860, 3,537,846 ; showing a decrease of 54,958. 
Pigs in 1859, 1,265,751 ; in I860, 1,268,590; showing an 
increase of 2,839-

1855 to I860, calculated according to the rates assumed by 
the Census Commissioners of 1841, viz.:—For horses £8
