satisfactory results. All my subjects were in highly contaminated 
premises, and none of them, although still occupying the same, 
have shown any symptoms of contracting the disease, although 
in several instances where fresh cows were introduced, and not 
protected by inoculation contagious pleuro-penumonia has been 
contracted and the animals have died. 
But to derive the full benefits of the principle it must be made 
obligatory and systematic, many of its details requiring to be 
scrupulously attended to. So far, under your instructions, my 
efforts have been devoted to establishing the efficacy of the prin¬ 
ciple, and have been hampered by the limited authority of your 
Board. In this consideration of inoculation, as stated above, I 
have viewed the subject as a matter affecting this local district 
which, from its geographical position, presents the elements for 
almost perfect isolation and quarantine, and the exportation of 
live cattle from this island being almost nil, even its entire pro¬ 
hibition, if necessary, would entail no serious loss. Seeing that 
much of the milk supply of this city is derived from dairies situ¬ 
ated immediately beyond the limits of your jurisdiction, such as 
in Blissville, Ridgewood, East New York, Flatlands and Flat- 
bush, and which are known to be districts highly infected with 
zymotic bovine lung fever, it will be necessary to at least 
bring them under the same strict supervision that is being given 
to the stables located in Brooklyn. 
The eradication of the disease in the United States would de¬ 
mand the action not only of local authorities or even of State 
boards, but also the energetic efforts and supervision of the 
national government. And while I thus advocate the adoption 
of inoculation to meet our local condition, in recently invaded 
districts and isolated cases, its extirpation can be more radically 
effected by the slaughtering process carried out in its entirety. 
In support of the above views allow me to quote from an 
article by George Fleming, LL.D., F.R.C.Y.S., of London, a 
sanitary veterinarian second to none, who says : “ There is at 
length a prospect of release from the ravages of one of the most 
serious scourges that ever visited the bovine population of this or 
any other country, if the government cares to adopt those 
measures which have now been proved to be completely efficacious
