Report of the International Commission on the Control of 
Bovine Tuberculosis, 1910. A copy of this has been received 
from the Department of Agriculture of Canada among other 
publications from the same source. It is the first report of the 
commission named, which was appointed by the American \^et- 
erinary Medical Association at its annual meeting in Chicago in 
1909, and was presented to that body at its annual meeting in 
San Francisco last September. The commission was a highly 
representative body, including university speciahsts, packing in- 
dustry experts, livestock association men, and board of health 
and experiment station professionals, nine members being from 
the United States and five from Canada. The president was J. 
G. Rutherford, C.M.G., V.S., H.A.R.C.V.S., Veterinary Director 
General and Live Stock Commissioner of the Dominion of 
Canada ; and the secretary, M. H. Reynolds, D.V.M., Professor 
of Veterinary Science, College of Agriculture and Experiment 
Station, University of Minnesota. There is some food for local 
pride in the discovery from the report that some of the findings 
and recommendations of the commission have been anticipated 
by the action of the Territorial authorities of Hawaii, following 
the initiative of the municipal government of Honolulu in legis- 
lation for pure milk. Some disconnected extracts from the re- 
port follow : 
There should be no sale or exchange of animals affected with 
tuberculosis except for immediate slaughter or for breeding pur- 
poses under official supervision." 
It is held ( 1 ) That tuberculin, properly used, is an accurate 
and reliable diagnostic agent for the detection of active tubercu- 
losis. 
''(2) That tuberculin may not produce a reaction under the 
following conditions: (a) When the disease is in a period of in- 
cubation, (b) When the progress of the disease is arrested, (c) 
When the disease is extensively generalized. The last condition 
is relatively rare and may usually be detected by physical exami- 
nation. 
"(3) On account of the period of incubation and the fact that 
arrested cases may sooner or later become active, all exposed 
animals should be retested at intervals of six months to one year. 
"(4) That the tuberculin test should not be applied to any 
animal having a temperature higher than normal. 
"(5) That any animal having given one distinct reaction to 
tuberculin should thereafter be regarded as tuberculous. 
''(6) That the subcutaneous injection of tuberculin is the only 
method of using tuberculin for the detection of tuberculosis in 
cattle which can be recommended at the present time.
