PORK POISONING ; DESCRIPTION OF A NEW INFECTIVE ORGANISM 
IN HAMS. 
Serious accidents having taken place at Welbeck Abbey, an 
inquest was made by Dr. Ballard, and revealed the fact that 
“ the seventy-two persons affected had all eaten hams ; thirty-six 
hours after, they had fever, choleric diarrhoea, muscular pains, 
vomitings and great prostration. Several of the sick ones died. 
Sent to London, the meat was examined by Mr. Klein. It con¬ 
tained no trichina, but in the raw or cooked meat, the muscular 
fibres were covered with baccilli and spores, in great quantity. In¬ 
oculated to healthy pigs, these microscopic organisms produced 
death in them. 
At the autopsy of one man who had died it was found that 
the glomerules of Malpighi, the arteriols of various tissues, were 
closed, obliterated by a large number of bacteria. Was this an¬ 
thrax, or the disease improperly called typhoid fever in the pig ? 
What is the origin of these parasites ? 
And again, at the same time, Dr. Seaton observed at Notting¬ 
ham, a similar affection, produced under similar conditions. Here 
also, hams were the cause of it, aud Mr. Klein found in them the 
same bacteria, of exactly the same nature, with those he had found 
in the hams from Welbeck ,—Revue d*Hygiene, 
HORSE POX. 
By M, J. Philippe. 
The 3d of November, 1876, the author was called to visit a 
mare slightly^ sick ; he found on the buccal mucous membrane and 
upon the tongue, pustules of horse-pox. Collecting the liquid 
from these pustules, several children and a cow were vaccinated 
with it. Six days later, the use of a twitch which had been used 
upon the mare produced horse-pox in another horse, and gave 
beautiful pustules. The vaccination was successful in most of the 
cases. 
When preserved in glass tubes, horsepox virus rapidly loses
