but are there not cases where the flesh may appear to be good,
and yet contain some subtle malign principle? It is an ascertained fact
that young or "slink" veal very frequently gives rise to diarrhoea,
more especially when that disease is epidemic. Dr. Parkes, in his
celebrated work on Hygiene, page 162 (second edition), states that
"the flesh of the pig sometimes produced diarrhoea--a fact I have had
occasion to notice in a regiment in India, and which has often been
noticed by others. The flesh is, probably, affected by the unwholesome
garbage on which the pig feeds." Menschell states that 44 persons were
afflicted with anthrax after eating the flesh of oxen affected with
carbuncular fever. Dr. Kesteren, in the _Medical Times_ for March, 1864,
mentions a case where twelve persons were affected with choleraic
symptoms after the use of pork not obviously diseased. At Newtownards,
county of Down, several persons died after eating veal in which no
poisonous matter of any kind could be detected. One instance has come
under my own notice where a man, two dogs, and a pig died after eating
the flesh of an animal killed whilst suffering from splenic apoplexy.
Several butchers have lost their lives in consequence of the blood of
diseased animals being allowed to come in contact with abrasions or
recently received wounds on their arms. The flesh of over-driven animals
is stated by Professor Gamgee to produce a most serious skin disease,
although the meat appeared to be perfectly healthy. The Belgian Academy
of Medicine has decided that the flesh of animals suffering from
carbuncular fever is unwholesome, and its sale in that country is
prohibited.

Many persons have died in Germany and a few in England from a disease
produced by eating pork containing a small internal parasite termed
_trichina spiralis_. I have recently met with a case of _trichiniasis_
in the human subject. The body of the unfortunate person--who had
been an inmate of the South Dublin Union Workhouse--was found to
contain thousands of the trichinae. In Iceland a large proportion of
the population suffers from a parasitic disease traceable to the use
of the flesh of sheep and cattle in which flukes abound.

Pleuro-pneumonia is in this country the disease which most frequently
affects the ox. It is probable that about 5 per cent. of these animals
sold in Dublin are more or less affected by this malady. There are two
forms of pleuro-pneumonia--the sporadic, or i
