hardly in a position to resolve this question. It is quite 
possible that examination of the animal may give nothing 
of a truly diagnostic nature. Fortunately, the history of 
the case will assist the practitioner. If the animal suddenly 
became affected, if it is not a fresh arrival in the country, and if 
pleuro-pneumonia contagiosa is not present at the time, it is 
certainly a case of the sporadic form of the disease. On 
the other hand, we must suspect peri-pneumonia, and ought 
to isolate the patient if he has been dull and had a cough 
for some time, and if he has been only a few weeks in 
that part of the country; peri-pneumonia may be already 
prevalent among other animals, or the sick animal may 
have come from an affected locality. These means of 
diagnosis are not truly scientific, but are practical and 
convenient. 
ON PLANTS IN RELATION TO ANIMALS.

It is impossible to dismiss the Brassiea tribe of plants 
without a few special remarks upon their uses in connection 
with stock, a subject to which we shall particularly pay 
attention in the present article. 
The Sinapis series afford plants which are somewhat 
relished by sheep, for which the Sinapis alba is very fre¬ 
quently cultivated. Throughout Wiltshire especially many 
acres of this plant are grown for sheep pasturage. When 
sown in spring it is thought that its stimulating properties con¬ 
duce to the bringing forward of the ewes,for which, indeed, it is 
often available when sown after early crops of peas, oats, &c. 
In both cases winter wheat can be sown after the mustard 
has been eaten off, which is considered a wise proceeding, 
especially where the wire-worm prevails, as it is, indeed, very 
fatal to this pest. 
When mustard is sown in spring it is no bad preparation 
for turnips, which may be put in as soon as the land is ready, 
and the manure derivable from the digested mustard is a good 
preparative for either rape or turnips. 
It is well to allow a little bruised corn with the mustard, 
as it beneficially aids the flock, and, besides this, it tends to 
keep the land in good condition.
