246 ANALYSIS OF CONTINENTAL JOURNALS. 
other veterinarians, principally by the late Dubois of 
Iodoigne, that the malady (stomatite aphtheuse ) is determined 
by a specific agent of an unknown essence in the air, or, in 
other words, by a miasmatic development, producing an 
affection wffiich afterwards becomes contagious, attacking not 
only animals of the same species, but also those of other 
species. 
If the principle of the malady is in the atmosphere, we 
cannot, by sequestration, protect animals from its influ- 
ence ; hence, we cannot depend on government measures to 
prevent its development, as has been forcibly pointed out by 
the late Professor Yerheyen. He said the government can- 
not control the elements, or sequestrate the miasma contained 
in the air; it must, therefore, be left to those most interested 
to mitigate the evil. 
Inoculation which is also recommended by superior autho- 
rity is not a preservative, the only advantage derived from 
it is to provoke the malady artificially which is by that 
means of greater benignity, as almost always the eczema is 
confined to the mouth. Amongst the symptoms which the 
author avers are sufficiently known, there is one which has 
not been described by any author, viz., the phlyctenae on the 
conjunctiva which cause intense inflammation of the mucous 
membrane accompanied by lippitude and epiphora. 
I have also observed, the author states, on three cows, that 
form of the malady which M. Ziindel of Mulhause designates 
catarrhal, of which mention was made a few years ago by 
M. Laridan of Bruges and M. Macorps, Sen. of Huy; this 
form of the malady is often mortal, particularly in young 
animals. The symptoms are numerous : confluent aphthae on 
the muzzle, lips, gums, and even in the nostrils, on the 
tongue, feet, and mammary gland, with a tendency to ulcera- 
tion ; the mucous membrane is of a yellow-reddish colour, 
there is an abundant salivation, thick and viscid, more or less 
difficulty in the respiration, loss of appetite, intense thirst, 
diarrhoea, grinding of the teeth, foetid odour from the mouth, 
arising from the putrefaction of the saliva; the animals fall 
awaj T visibly ; as the proprietor expresses it, they ee melt aw 7 ay 
at sight.” 
The author has inoculated the malady at the muzzle, with 
the fluid from the phlyctense on the toothless gum of the 
upper jaw, by means of a double-edged knif e,feuille de sauge i 
in the same way as he inoculates for pleuro-pneumonia ; and 
well-developed vesicles have appeared at the spots of the 
incisions. He has also with success employed the method 
practised by M. Masson de Dour ; viz., by taking the tongue
