VACCINE AND CALF VACCINATION. 
commonly yielded by the affected udder, but it appears that 
no result has occurred, proving that the serous fluid of the 
vesicle or bulla was neither specific enough to irritate the 
hand of the milker, nor to be reproduced on the calf by inocu¬ 
lation. I introduced some points into the arm of a child with¬ 
out any result , and rubbed three points on a cluster of 
scratches on the bach of my left hund , with the same result . 
In cases where the fluid of such vesicles or bullrn has 
become acrid, I have several times reproduced a vesicle on 
that part of the hand in perfection; and some years ago I 
made an old man very ill by inserting some serum of the same 
kind into his arm. Some day I will show you the drawing of 
that inoculation, and drawings of casual vesicles and bullae 
on the hands of milkers. ' Yours truly,

In a subsequent latter received from Mr. Ceely, he says 
that no result folloioed the use of some of the points charged 
at Halstead which I gave to Dr. Cory, the vaccinator at 
the Local Government Board’s station at Rowland Hill’s 
Chapel, Blackfriars Road. I was prepared to expect nothing 
more from their use than what ordinarily results from the 
spurious vesicle, as I did not see any indications of the 
source of the fluid being of the nature of true vaccine. 
The spurious vesicle will sometimes reproduce itself, as I 
have proved on myself and others, but not always. I was, there¬ 
fore, not disappointed in the trials with the Halstead points. 
Addendum. 
In connection with the subject of variolous affections of 
domestic animals we insert an extract from the Mark Lane 
Express , August 8th, relative to the affirmed transmission 
of equine variola to the calf. 
“ According to the Gazette Medicate , among the horses of a 
German horse-dealer, on May 5th, M. Alexander showed 
to M. Le Blanc a case of horse-pox in a well-bred animal 
from Germany. Lymph from this animal was inoculated 
by M. Chambon, on a three months’ old heifer, by three 
punctures on the udder. These inoculations were most 
successful, and from this heifer another was as successfully 
inoculated on May 13th. On the 19th there was a very fine 
vaccinal eruption, no fewer than sixty pustules being present. 
With the lymph from these two other heifers were vacci¬ 
nated, and from them the vaccination department of the 
Socidte de Hygiene was amply supplied with lymph for 
vaccination purposes.”
