90 MICROSCOPICAL EXAMINATION OF MEASLED PORK. 
DISEASE IN CAVALRY HORSES. 
A letter from Poona informs us that a very extraordinary 
disease has attacked the horses of the 14th Light Dragoons. 
It resembles the cholera in all respects. Many of the 
animals are violently purged in the first instance ; others 
are seized with cramp, and die without being purged.

NOTES OF A MICROSCOPICAL EXAMINATION OF 
"MEASLED” AND OTHER PORK. 
By William Smith, F.L.S., Professor of Natural History, 
QueerPs College, Cork. 
The subject of the present paper has of late excited much 
attention in this locality, the trade of the port of Cork and 
the industry of the neighbouring counties being immediately 
connected with the produce and export of provisions, a main 
portion of which consists of cured pork. 
The disease in pigs popularly known as cf measles 55 (though 
without any resemblance to the complaint bearing the name 
in the human subject) is one of frequent occurrence in the 
South of Ireland, and as its presence in the flesh of the 
animal is usually regarded as detrimental to its value as an 
article of food, the market-price of the commodity is thereby 
lowered, and the profits of the producer proportionally 
diminished. 
Questions connected with the supply of provisions to the 
Crimean army having called increased attention to this sub- 
ject, an attempt was lately made by the provision-merchants 
of Cork to arrive at more certain conclusions respecting the 
nature and extent of the disease, and its precise influence on 
the character and condition of the flesh affected by it. 
Having been invited to assist in this research, by reporting 
on the microscopical appearance of the disease, and the meat 
affected by it, the following notes of a careful examination of 
fresh and cured pork, supplied to me, were my contributions 
to the inquiry : 
The facts noted are not new to science, the subject having 
attracted the attention of several German, French, and 
British physiologists, and the results of their investigations 
being for the most part similar to my own.
