536 SELECT COMMITTEE ON CONTAGIOUS DISEASES BILL. 
take as an example the case of a cow which becomes infected 
in one of the London dairies. This animal is living with a 
number of others, in a low building, very badly ventilated, 
and kept in a dirty and filthy state. Such causes predispose 
the animals to this disease, as well as to many others, and 
those causes also hasten on such affections as pleuro-pneu- 
monia to a fatal termination. The disease would proceed 
much more rapidly under such circumstances. Then we 
should find, in what may be called the second stage of the 
disease, that a difficulty of breathing exists, that the appe- 
tite is lost, the cough more frequent, the pulse increased, the 
coat staring, and so on. In a still later stage of the disease, 
the breathing would become still more laboured and difficult, 
and the surface of the body would be irregular in its tem- 
perature. For example, the horns and the ears and legs 
would be cold, while other parts of the body would be warm. 
Rigors will now and then show themselves, the pulse will 
become more frequent, and the animal be found to grind its 
teeth, as an expression of pain, and moaning, as another 
expression of pain. The bowels at this stage of the disease, 
become not infrequently irregular, and in fact diarrhoea sets 
in, and in the still later stages of the disease the food which 
is in the stomach goes into a state of fermentation. The 
animal becomes tympanitic, the bowels more irregular, the 
body deadly cold, the pulse nearly indistinct and rapid, and 
in this condition it dies. 
66. Are you able to state the various symptoms from day 
to day? — I have stated, that supposing the animal is exposed 
to such causes as would hasten on the disease, all that 1 have 
just narrated may take place in the course of a week or so. 
In other cases, where the animal is not exposed to such 
causes, it may linger on for a fortnight, three weeks, or a 
month. 
67. Now, in the early stages to which you have alluded, 
the staring coat, and the like, would it not be very difficult 
for an inspector to say whether such an animal was or was 
not suffering under pleuro-pueumonia, or merely from the 
effects of cold l — Yes, certainly, it would be difficult. 
68. Would not over-driving and a sudden chill give very 
much the same appearances that present themselves in beasts 
that are suffering under the early stages of pleuro- pneu- 
monia, namely, the loss of appetite, the staring of the hair, 
and the general appearance of cold ? — Causes of that kind 
might give rise to a state of the system which would have 
some analogy to the symptoms in the early stages of pleuro- 
pneumonia.
