OBSERVATIONS ON THE LUNG PLAGUE OF CATTLE. 783 
B. Brainy Lorimer Street, Brooklyn, Lad a yearling heifer 
that had been kept in the Blissville distillery stables prior to 
their quarantine in Feb. 1879. Her infection therefore dated 
back to January. July 26th he applied for a permit to send 
this heifer to the country, but on examination she was found to 
carry a large mass of encysted lung. She was sent to the 
slaughter-house, being in fine condition, and a large encysted 
mass was found as expected. On August 22nd a fine short¬ 
horn cow that had been sent from a healthy district through our 
iaspection yards direct to Braun's stable was found very ill with 
Lung Plague and had to be slaughtered. 
In place of furnishing further cases of my own it may be 
well to quote one from another source confirmatory of mine. 
In the Recueil de Medecine Veterinaire , March, 1879, M. 
Baboiiam records the case of an ox supposed to have chronic 
bronchitis, and brought from a stable where Lung Plague 
formerly prevailed, transmitting the disease to the healthy stock 
of his purchaser. 
The danger from animals bearing these encysted masses are 
hardly less than from those still in the incubative stage of the 
disease. Be it understood that many cattle that bear such 
masses have natural pulse, temperature, and breathing, will lay 
on flesh, or yield as many as fifteen quarts of milk per day, and 
it can be easily perceived how such animals will change hands, 
and pass into fresh and susceptible herds without any conscious¬ 
ness of wrong on the part of either buyer or seller. Such 
animals may any day carry infection from state to state, or from 
the infected states to our unfenced territories, where, owing to 
the constant commingling of herds it will be impossible to 
eradicate the virus. Many such cases can with difficulty be 
detected even by the most carefully conducted professional 
examination, much less are they likely to be recognised in the 
hurried examinations that can be given to large numbers of 
animals at a frontier. In short, these chronic cases with en¬ 
cysted necrosed lung, and the long period of incubation of the 
Lung Plague condemn absolutely the passage of animals on a 
mere examination, and without the attendant quarantine of three 
months. Cattle for immediate slaughter may be passed under 
such precautions as shall prevent their contact with or proximity 
to store cattle, but the passage of store cattle on examination 
only betrays the unfitness for his office of him who prescribes it. 
The same considerations show the utter inadequacy of any 
measures that fail to reach every infected locality and every 
infected herd, and to prevent the shipment of any cattle from 
any infected district. 
To have suppressive measures effectual, either there must be a
