produced some of the fat from the Dutch butter factory, and 
stated that it was sent to Holland to be mixed wdth 
Dutch butter, and re-exported to England. A Witness — 
The Dutch butter factory manufactures tons upon tons of 
the stuff. Mr. Charles Young — That is so ; and it is sold in 
our shops as “ real Dorset/ 5 and tc real Cambridge/ 5 or 
“ genuine dairy-fed butter. 55 Mr. Paget — When "we pay for 
butter we have common fat ? Mr. Charles Young — Yes, 
sir. Mr. Paget said no doubt a serious robbery had been 
committed at the Dutch butter factory, but there was no 
evidence to justify him in remanding the prisoner for being 
concerned in it. If additional testimony could be obtained, 
the prisoner could be arrested again. At present he should 
discharge him. — The Echo. 
Improvement in the Preparation of Carbonic 
Oxide. — In its most valuable and well-prepared summary of 
foreign chemical progress, the Chemical News gives the fol- 
lowing abstract of a paper on this subject : When the gas 
just alluded to is evolved from a mixture of oxalic and sul- 
phuric acids, as is well known, a mixture of carbonic acid 
and carbonic oxide gases is obtained. This mixture of gases 
the author causes to pass through a tube made red-hot in a 
suitable furnace and filled with charcoal previously well re- 
burnt ; and, after having washed the gas through a solution 
of potassa, and also lime-water, he thus obtains a bulk of 
the pure carbonic oxide gas three times larger than w^ould be 
the case if the carbonic acid simultaneously formed were not 
decomposed byjthe red-hot charcoal, w 7 hich must be free from 
yielding any carburetted hydrogen gases. — Popular Science

Injection of Liquor Ammonite in Snake-bite. — 
Dr. Fayrer, of Calcutta, has made a very concise experiment 
to test the value of Dr. Halford 5 s method of injecting Liq. 
Ammon, in cases of snake-bite. We ourselves some time ago 
expressed an a priori conviction that the remedy w 7 as as bad 
as the disease. Dr. Fayrer has lately [Indian Medical Gazette , 
July) described one of his experiments on a dog, and he thus 
sums up his observations : — The object of this experiment 
v T as to test the effect of the Liquor Ammoniae injected into 
the venous circulation in an animal uninfluenced by the poison. 
It was used of the sp. gr. *959 B. P., as directed by Pro- 
fessor Halford, and it was injected into the femoral vein in 
the manner suggested by him. The impression produced by 
this experiment was that the dog had a very narrow escape 
from death, and that the effects of the ammonia had nearly 
proved rapidly fatal. — Ibid.
