source of sulphurous acid; the nitric oxide being prepared 
from the sulphate of iron, nitric acid, and sulphuric acid. 
This last process was the only one that furnished an acid free 
from arsenic. To discover the source of the arsenic, he 
obtained a specimen of sulphur from a manufacturer of acid 
which was guaranteed as free from arsenic. This specimen 
when burnt into sulphurous acid w T as found to contain 
arsenic, and even the residue left after combustion contained 
traces of the metal. In preparing an acid free from arsenic 
he had found that it was necessary to conduct the operation 
at a8 low a temperature as possible. 
Dr. Franklancl said it would be very satisfactory if sulphuric 
acid free from arsenic could be prepared in any quantity. 
Mr. Dugalcl Campbell inquired what was the smallest amount 
of arsenic that could be detected by Mr. Bloxam’s method, 
for by his own method, which would detect a very small quan¬ 
tity, he had found samples of sulphuric acid which were free 
from arsenic, but that it was always present in samples of 
hydrochloric acid, and that it was more important to obtain 
this latter acid pure. He also stated that he had fo.und 
arsenic in common salt. 
Mr. Bloxam said that he had distilled common salt with 
sulphuric acid, and had found arsenic in the distillate, but 
that he obtained none from chloride of ammonium and sul¬ 
phuric acid.

From an interesting paper, abounding in statistical in¬ 
formation, read by Dr. Milligan before the Society of Arts, we 
extract the following : 
“ Horses sheep, cattle, and pigs were exported from Tas¬ 
mania to the value of <£60,900 in 1859. 
“ The feats of Tasmanian horses on the turf early esta¬ 
blished for the colony the reputation of possessing the best 
blood and bone in the Southern Hemisphere. The late 
governor, Sir W. Denison, was a warm patron of the turf, 
and frequently went out with the hounds, proving himself as 
fearless as firm in the saddle. The gold of Victoria has now 
effected a transfer of much of the horseflesh of Tasmania to 
the opposite shores. 
“The breeds of cattle which have been introduced into the 
colony are the Durham or Short-horn, the Hereford, the 
Ayrshire, the West Highland, and the Devon. These have 
all, at one time or other, and to a greater or less extent, been
