VETERINARY JURISPRUDENCE. 
but we cannot always do so. Mr. Poole Leigh is a much older practitioner 
than I am: he came to see the horse after it was opened—he has given up 
practice now. He had, upon that occasion, a full opportunity of seeing the 
state of the lungs. 
Mr. Nathaniel Poole Leigh was then called^ and examined hy Mr. Crowder. 
—On the 12th day of April I was sent for by my friend to see a horse exa¬ 
mined. I did not get there until it had been opened some time. Mr. Kent 
had sent several times for me, but it was not quite convenient for me to go: 
he could not get any one else, and I went. I saw the whole of the lungs 
except two pieces that had been cut out before I got there. I was there 
sufficiently long to observe that it had had inflammation of the lungs and 
bowels. I gave a certificate to Mr. Kent for the purpose of being shewn to 
Mr. Fisher. I should say the horse was diseased before the 15th of March. 
I consider that it had been standing for some considerable time,—I should 
say, at least from three to four months. There was a thickening of the pleura 
and substance of the lungs,—the lung was become scirrhous or hardened. I 
concluded from the dissection that long previous disease was indicated. I 
have been in practice for forty years, and during that time have seen a great 
many horses dissected. 
Cross-examined hy Mr. Erie. —There was inflammation of the bowels and 
lungs. The lungs were inflamed all over, but I think the greatest disease 
was near the centre of the right lobe. The whole of the lungs appear to have 
suffered from acute inflammation : I think both lobes were affected, but the 
right was particularly so. The diseased part was near the centre. The lung 
in that part had lost its elasticity—the diseased part was about the size of 
a half-crown, and about an inch in depth when cut into: it was to this part 
that my attention was drawn—it had been cut into before I came there. 
There were similar patches in two or three places on the lungs: one had 
been cut out, and another was cut into and placed in a bucket of water; 
these patches would be the result of acute inflammation, and are formed 
more speedily at some times than at other times. It is caused by inflam¬ 
mation, which produces a thickening of the membrane that envelopes the 
lungs as well as of the substance of the lung itself. Upon examination, I 
found that all these parts were become completely organized, therefore the 
disease must have been of long standing; I should think that it had been 
formed longer than three months: I cannot state within a month or two 
what time would be requisite for that formation, because I must know the 
habit of the horse and his previous state of health. Inflammation of the 
lungs frequently occurs without any cough, and it sometimes follows a cough. 
A horse with inflammation of the lungs avoids coughing as much as he can, 
on account of the pain which it gives him. Inflammation generally accom¬ 
panies cough, but we have often inflammation of the lungs without a cough. 
When the lungs are indurated, the horse frequently recovers. In this case 
the inflammation had subsided, and left an induration of the lung and a 
thickening of the membrane. I have seen that induration in various stages 
of its formation. You can only judge of its progress by watching the treat¬ 
ment of the horse. There is an analogous formation of this kind in a part 
where it can be seen—a thickening of the conjunctiva of the eye—that varies 
in proportion to the violence of the inflammation. The thickening of that 
membrane may be brought on in a few days, for it is a delicate organ. The 
length of time required to produce this thickening depends on the degree of 
inflammation. If I had dissected the parts I could have formed a better 
judgment of the time, for then I could have seen the extent to which disease 
had gone. I wished that I had been present from the commencement of this 
trial. I wished to have heard the history of the horse, and then I could have
