We feel much pleasure in resuming our extracts from this clever 
performance ; which it is our intention, on the present as on the 
former occasion, to make as lengthy as our space will permit us to 
do ; and having done so, we shall conclude with a remark or two 
touching the prominent points of the subject of them, comparing, as 
we go along, the opinions thereon contained in the pamphlet before 
us with those pre-expressed on the same points by Mr. Waters* ; 
in the hope that, on a disease which has proved the source of so 
much loss of property to the agriculturist, and of so great concern 
to the veterinarian, we may be able to elicit some facts which may 
be useful as beacons to direct those on their way who may here- 
after have to steer their course through a department of veterinary 
therapeutics, the labourers in which have hitherto discovered but 
little that has turned to any useful or satisfactory account. 
“ The primary symptoms of pleuro-pneumonia are generally ob- 
scure, and too often excite but little attention or anxiety. As the 
disease steals on, the animal becomes dull and dejected, and, if in 
the field, separates itself from its fellows. It becomes uneasy, 
ceases to ruminate, and the respirations are a little accelerated. 
If it be a milk-cow, the lacteal secretion is diminished, and the 
udder is hot and tender. The eyes are dull, the head is lowered, 
the nose protruded, and the nostrils expanded. The urine generally 
becomes scanty and high-coloured. It is seldom thought that much 
is the matter with an animal until it ceases to eat ; but this criterion 
does not hold good in most cases of pleuro-pneumonia, for the 
animal at the outset of this disease still takes its food, and con-
