The Committee on Houses for Working People undertook to secure data by writing to the secretaries of the state boards of health, the health officers of the larger cities, the U. S. Public Health and Marine-Hospital Service, the National Housing Association, the Bureau of Labor, the National Association for the Study and Prevention of Tuberculosis, the Russell Sage Foundation, city housing associations, and other civic and philanthropic organizations, besides a number of industrial organizations and individuals whom we had reason to believe were interested in this work. From these reports, it is apparent that the interest in this subject is wide-spread and that many movements are in contemplation regarding the best housing conditions for working people, others are being inaugurated, while a few places have done active work. It appears from the reports received that the tenement-house plan, even the so-called model tenement-house, has not provid satisfactory, the consensus of

The four tests which I shall discuss are Nonne's Phase 1 or ammonium sulphate reaction for determining an increase of globulin in the spinal fluid, the method for determining whether or not the lymphocytes are increased, and the Wassermann tests in the blood and in the spinal fluid. A fear has been expressed that by a multiplication of reactions the practice of medicine will eventually be reduced to a rule of three. Much 1 says of the Wassermann reaction that it controls the clinic and, on the other hand, is controlled by the clinic. This is true of all other reactions. Their significance must be construed in accordance with the clinical facts. Nervous syphilis presents a great variety of symptoms, none of which can be said to be characteristic of it more than of some other disease, as multiple sclerosis or brain tumor. The four tests are valuable as aids

The synthesis of NN-di-(2-chloroethyl)aniline specifically tritiated in the positions meta to the nitrogen mustard group by catalytic halogen–tritium exchange with the 3,5-di-iodo-derivative is described.

Statistics, together with the dreadful nature of the disease, demand that any and every method proposed for the early diagnosis of cancer should be thoroughly and impartially tested. Emil Abderhalden of Halle, Germany, recently presented to the medical profession a biologic test that is demanding the closest attention. Time alone can thoroughly prove the accuracy of his test, and only as impartial reports of large numbers of cases examined are offered by reliable workers. It is readily apparent by a casual review of the literature pertaining to the test that the differences in the results obtained are due to some variation as to technic, selection of tissues used as fundaments, unless the test is unreliable. Frankel states that the Abderhalden reaction was not reliable in the cancer cases examined at the research institute at Heidelberg, while Frank and Heimann, Marcus, Epstein, Erpicum abroad, and Lowry in this country report more
