ON SPASM OF THE DIAPHRAGM.

particular spot, for, on putting my ear to the side, I could define 
it distinctly, and in this case it was nearly under the twelfth rib, 
at its most projecting part. The pulse at the jaw flowed regularly 
and distinctly. 
About four o’clock I noticed an unusual circumstance — at 
least I had not observed it before— that occasionally, when an 
expiration was about half accomplished, the spasmodic action 
was not to be seen, or, at any rate, the least in the world, now 
and then. During this state of apparent relaxation, the pulse 
continued as usual. 
Towards ten at night the spasm had nearly ceased, and the 
next morning entirely so j but the physic was operating more 
freely. 
Case II. — Sept. 30th, 1842. Early this morning the abpve 
pony was found in a similar state of spasm of the diaphragm as 
before. He had not been working, or out of the stable, for 
several days past. Yesterday he had eaten half a canful of po- 
tato peelings and bran ; the former were cold, but the latter was 
warm. 
9 a.m. — I now saw him for the second time. He is in the 
same state as before. The beating is still only on the near side. 
The pulse and spasm are 60 in a minute, and each follows the 
other with great regularity. The pulse at the jaw is quite dis- 
tinct, but is small and hard. At the heart the pulse is to be felt, 
but not very distinctly so, being confounded with the spasm and 
shaking at the side. The beating at the side appears to come, 
as Mr. Castley and Mr. Brown have observed, “ from before back- 
wards,” and, on attentively observing, it seems as if the blow was 
given nearer the heart, and a gradual undulation of the sides out- 
wards, from before backwards, takes place just like the waves on 
water. The spasm at the side is evidently more distinct and 
powerful during inspiration than expiration. The faeces are moist. 
He does not seem well — he is rather heavy, and his mouth a little 
clammy. Give 3 ij opii in a moist ball. 
5 p.m. — About the same: give 3i*j of aloes Barb., and 3i 
ammon. sesqui-carb. in a ball. 
8 p.m. — The same. I have seen him several times in the 
course of the day, and watched him attentively. I generally 
found him lying down, and comfortable and warm all over. He 
has eaten scarcely any thing all day. The beating at the flank 
is distinctly more visible during inspiration, and it is at from 
about the tenth to the fourteenth rib, and at the middle of their 
length. 
Oct. IsJ, 8 a.m. — But little difference from the preceding 
night, but, if any thing: the pulse and the spasm are quicker,
