FROM ANIMALS TO THE HUMAN BEING.

told, that, in the month of April of the last year, he had bought 
a calf labouring under this disease, which he had imprudently 
placed among his home-bred cattle, and to which it had transmitted 
the disease. They had communicated it to others; and, from 
that time, his calves always had the dartres. At one time he 
sold them all and bought others, in order to rid himself of the 
nuisance: but, in spite of this precaution, the disease broke out 
on the new-comers; and this convinced him that the disease 
could also be communicated by mediate contact. 
In the course of feeding these animals, Barrot himself had 
eruptions on the wrist and around the eye: his wife also did 
not escape infection. They were thoroughly convinced of the 
contagiousness of this malady ; and when they were compelled to 
touch the calves, they did it with a great deal of caution, and 
immediately afterwards washed their hands with vinegar or 
soap. 
Case VI.—On the same day M. Blanc, of Croix-Dausade, 
requested me to examine five calves, from three to three and a 
half months old, which he had in a corner of his stable. They 
all had the furfuraceous dartres, and on various parts of their 
bodies. 
On the 15th of November M. Blanc had purchased a calf that 
had the dartres, and had placed it with the calves of his own 
breeding. They were all infected in the space of seven or eight 
days. He himself was not exempt from the contagion, for he 
had on his arm an eruption that sadly incommoded him by its 
itching. 
Being from other illness compelled to take to his bed, his wife 
had the management of the calves; and in the course of eight 
days she began to have a tormenting itching along her neck 
and the course of the spine. There were many little swellings 
(boutons) uniting into patches, and permitting a limpid fluid to 
escape, which, hardening, formed numerous little scales resem¬ 
bling the husks of bran. I never saw dartres so extensively 
spread as on the husband. He had some as large as a hand— 
others of the size of a six-franc piece; some being isolated, and 
others united by their edges. 
These four last cases appear to me sufficiently to confirm the 
contagiousness of dartres. In another article I shall touch on 
the contagiousness of charbon, and of malignant pustules.
