-li- lt should be cautioned that tests of the pharmacological activities of shed blood are full of hazard because slight differences in the way the tests are made mayjnake large differences in the results'obtained. Therefore, many members of tfce Committee on Prpblems of Alcohol believe that this work needs confirmation, before too much Weight should,be put upon the results.
