THE LATE EPIDEMIC DISEASE IN FRANCE. 
4th. By gangrene : then the gland, or the entire udder, falls 
off, and an infectious smell spreads around. 
Induration also sometimes follows the suppuration, or the 
inflammatory swelling assumes a chronic state : then the gland 
remains hard and painful. It often participates in the engorge- 
ment of the part, and this may again determine the loss of a 
portion or of the whole of the gland. Often also the teat be- 
comes gangrenous in some part of it, or even in the whole : in 
this state, if the cow is milked, the fluid is withdrawn with trouble, 
and a reddish matter, bloody and extremely foetid, escapes. This 
complication is much to be dreaded : it not only suppresses the 
secretion of the milk in whole or in part, but it destroys the appe- 
tite of the cow, who grows thin, falls into a consumptive state, 
and can be fattened no more. 
Swellings of the udder occasionally appear suddenly, and with- 
out any known cause. They attack more particularly cows who 
are put up to fatten : they fix themselves on a gland without pro- 
ducing much induration, or after that is passed. These cows 
suffer very much, and rapidly lose flesh. 
These inflammations of the udder have appeared at the mo- 
ment when, the appetite of the cows being returned, the discharge 
of milk had resumed again its primitive state. The farmers 
then believe their cows are cured, and they say that the disease 
was so little troublesome that there is nothing more to be done. 
Indeed, in several cases the epizootic had been so mild, that 
the farmers have abandoned their cows to themselves, and left 
them to graze at their pleasure. But all have not been so fa- 
voured ; and, besides the complication that we have just pointed 
out, we will speak of another which was particularly prevalent in 
the summer of 1841. 
The disease of the feet, which they believed to have been cured 
among the greater part of the cattle, or which was in a way to be 
cured, has appeared again in several herds, also upon several sin- 
gle cows, but in very different degrees, from simple lameness even 
to the impossibility of rising. If the animals were forced to get 
up, they fell down again immediately, manifesting a dreadful de- 
gree of pain, which determined such an acceleration of breath- 
ing that the animal was almost suffocated. These last symptoms 
progress slowly, and do not shew themselves until a greater or 
less time after the attack of the disease on the feet. At this pe- 
riod, if the feet are examined, no more pustules will be found, 
and often even all trace of them has disappeared ; but there is 
heat, pain, and swelling, which sometimes extend even to the 
summit of the fetlock. The hoofs widen, and exhibit the integu- 
ment which unites them. In the major part of these eases the
