118 ON AN APHTHOUS AFFECTION AMONG CATTLE. 
the 2d of August the buccal membrane swelled ; on the 3d the 
edges of the tongue, the lips, and internal surface of the cheeks 
became covered with little vesicles, the largest of which was about 
the size of a pea. They were of a yellowish white, and contained 
a whitish fluid matter. Other vesicles of the size of a grain of 
millet were developed on the hands and fingers, and occasioned 
much itching. On the 4th and 5th the vesicles of the mouth in- 
creased in size, and broke on the following days: the fever soon 
afterwards disappeared, the scabs dried up, and the epidermis de- 
tached itself from the parts affected about the 20th of August. 
Messrs. Mann and Villain were not so severely attacked as M. 
Hertwig, but on them there was an eruption of little vesicles on 
the buccal membrane. 
Of these facts M. Delafond is doubtless ignorant, since no mention 
is made of them in his “ Police Sanitaire” At the time that 
was published, he was only able to refer to Michel Sagar and the 
veterinary surgeon in the environs of Lyons, in support of his 
opinion. 
On the authority of facts thus slightly authenticated, we would 
again ask how M. Delafond could suffer himself to be thus imposed 
on, while numerous talented veterinarians had from personal ob- 
servation deduced a diametrically opposite opinion. Those cases 
reported by himself, and extracted from the writings of Toggia and 
Mathieu, the former of whom studied the disease in Italy, and the 
latter on the Vosges, both talented and conscientious men, are they 
not of a nature to inculcate in his mind an opposite conviction] 
Now, lest M. Delafond might turn against us the weapons we 
have furnished him with by reporting the cases of the German 
veterinary surgeons, we will next proceed to examine them. And, 
first of all, let us oppose to the facts stated, 
First, those with which we are personally acquainted, those 
collected in numbers during the prevalence of the epizootic which 
we ourselves observed ; 
Secondly, those related by M. Rayer, M. Fobre, and M. Levigny, 
who all testify to the innoxious qualities of the milk. According 
to the last-named gentleman, it was even more creamy. 
Thirdly, those last, and most conclusive of all, given in the Re- 
port to M. le Prefect of the Seine by the Consul of Health at 
Paris. The following is a summary : — 
“ The milk of diseased cows, considered with regard to its effect 
on the health of human beings, does not appear to be productive of 
the slightest inconvenience , and all examinations of it, whether 
chemical or microscopical, have not been able to trace any charac- 
teristics that might lead to the fear that its effects would be 
pernicious.”
