ECZEMA EPIZOOTICA. 
889 
Left to nature, the animals affected with this complication 
infallibly succumbed towards the fourth day—the ninth of 
the disease. 
Those cured rapidly recovered, though often with the loss 
of their hoofs. 
The prognostic was always serious, for the malady was 
much more contagious than the ordinary aphthous fever; it 
was more unfavorable for calves than adults, though out of 
thirty-six of the latter eight died. 
The treatment was varied according to the indications, but 
was always simple. The calves were separated from the 
mothers, and fed artificially. 
Severe measures of sanitary police were resorted to, and 
the flesh of the diseased animals was not allowed to be 
sold. 
Lafosse, sen., had observed this complication of aphthous 
fever more than a century ago, but since that time it has 
been rarely mentioned by veterinary writers. In the Comptes- 
Rendus of Zurich for 1846, there is allusion made to the case 
of a calf that died of aphthous fever, after being fed on the 
milk of a cow affected with that disease, and in whose 
stomach ulcers were found. 
Petri, in the Annales de Bruxelles for 1843, speaks of 
several instances in which the milk of diseased cows has had 
a deadly effect on calves and . young pigs. Observations of 
the same kind have been made in Germany by Tannenhauer, 
and Hering admits that in the “ millet^"’ of young animals the 
aphthae may extend to the larynx, oesophagus, and even to 
the stomach, and produce a deadly form of the disease, 
accompanied by dysentery. 
Spinola speaks of aphthae on the pharynx, which may 
become ulcers; but he does not mention vesicles in the diges¬ 
tive canal, nor yet dysentery. Roll, in his treatise on vete¬ 
rinary pathology, says that aphthous fever is often complicated 
with catarrhal affections of the respiratory passages, in¬ 
flammation of the pharynx, and an acute gastro-intestinal 
catarrh. 
Delafond is the only author who has come near M. 
ZundeFs description of the complication. In his ^ Traite 
de Police SaniLaire,^ he admits diarrhoea to be a frequent ter¬ 
mination of the second period of aphthous fever. mucous 
or bilious diarrhoea soon accompanies this condition, and the 
animals, promptly prostrated, lose condition and die."” And 
again:—“At the autopsise of the animals, there are found 
ulcers with red margins, involving the thickness of the mu¬ 
cous membrane, in the nasal cavities, the larynx, trachea, soft
