ON A SWELLING OF THE UDDER. 
387 
I On the 1st August, 1827, it had grown as large as an apple, 
id often occasioned halting. Around the large one were several 
ttle tuberculous tumours. 
On the 22d of the month, the first time M. Jacob (V.S. in 
ie French Artillery) saw it, the tumour was hard, shining, 
regularly knotty, and painful to the least impression: it con- 
?aled the teat, and impeded the animal from working; whose 
ipetite at this time was bad, and she was falling away. 
23d. The mare was let blood from the thigh, w r as clystered, 
id poultices were applied to the swelling. The next day, 
ventv-four leeches were applied. During this treatment, the 
unour neither enlarged nor decreased : some of the little ones 
:oke, and issued a yellow matter. 
August 1st. For bloodlettings and poultices, M. Jacob sub- 
ituted frictions of strong mercurial ointment; but they speedily 
xasioned so much tumefaction, that he was compelled to have 
j course to bleeding and poulticing again. This plan reduced 
ie tumour to its former dimensions, but not down beyond 
lem. 
17th. M. Jacob commenced the employment of frictions of a 
Dinade of hydriodate of potash. Four days afterwards there was 
sensible diminution of the tumour. On the eighth day he used 3ifs 
f the ointment; and afterwards increased the quantity to 3ij, 
ith evident advantage. The swelling went rapidly down, 
ad at the same time grew soft; and both the lumps and the 
ain left it. Two months from the time of using the potash, the 
lare became quite restored : her udder re-acquired its natural 
olume, softness, and mobility.

Specific Ophthalmia. 
1. Ma rrimpoey, in a paper he wrote on the subject for the 
Loyal Agricultural Society of France, has divided the disease 
ito two kinds :—one that proceeds from hereditary influence; 
nd one that arises from causes quite extrinsic to the disorder 
self or family temperament. As proofs of the hereditariness of 
he disease, he offers the following cases: 
1st. A Spanish stallion, five years old, who had already suff¬ 
ered from to attacks of the specific ophthalmia, was employed 
get stock, and on account of his excellence was much sought 
fter by the farmers in the neighbourhood. None of the mares 
.e covered had ever had the disease ; but, notwithstanding that, 
ialf the progeny became affected with it: some going blind; 
thers only having it in one eye; others again getting off* with 
ome slight opacities upon the crystalline membrane.
