FACTS AND OBSERVATIONS. 
The Transmissibility of Tuberculosis. — So much 
has been said on the affirmative side of this question, that 
the views of M. Dubuisson, published in the Gazette Medicate t 
are deserving attention. After describing numerous experi- 
ments, this young physiologist lays down the following 
conclusions: — 1. The inoculated materials are generally 
harmless whatever may be the nature of the substances em- 
ployed. 2. They occasionally produce rapidly fatal symptoms 
— death being apparently caused by a sort of poisoning. 
3. In a few cases lobular pneumonia is observed, and should 
probably be regarded as the result o£ the inoculation; here 
the hepatized tissue might be mistaken for tubercles. 
4. Tubercular tissue given as an aliment may occasion death, 
as would similar septic products. 5. Generally, however, 
the animals that eat of tuberculous lung experience some 
malaise from this improper alimentation, but do not become 
tuberculous. These conclusions, confirmed by other ob- 
servers, demonstrate that tuberculosis is neither virulent nor 
contagious nor the animals experimented upon. — Ibid. 
Preserving Iron and Steel with Sulphur. — A mode 
of protecting iron from atmospheric influences has been pro- 
posed by Messrs. Macmillan and Macgregor, of Dumbarton 
and Glasgow. They bring melted sulphur into contact w r ith 
the cold metallic surface to be coated. The sulphur chills 
and sets into a hard, thin protecting covering . — The Journal

Meat Supply’. — It is stated that extensive arrangements 
are now being made in Prussia for the slaughter and pre- 
paration of meat, to be supplied via Hamburgh to the London 
market. English slaughterers have been sent over to dress 
the meat, and hind-quarters only are to be imported into 
England. — Ibid. 
Preserved Fish. — The Sydney Empire states that a new 
export has been added to the list of Australian products, one 
from West Australia, the manufacture of preserved fish, and 
the inventor has succeeded in producing an article quite 
equal to that imported from England and America. Large 
quantities of preserved fish are annually imported into 
Sydney, while a full supply of the raw article is to be found 
along the coast. — Ibid.
