Per cent. Number of cases giving evidence of the disease clinically or having a positive Wassermann reaction 156 or 65.5 Number of cases giving positive Wassermann reaction 137 or 57.5 Number of cases giving a positive history or presenting symptoms of the disease 85 or 35.7 Number of cases which were verified by both history and Wassermann reaction 64 or 26.9 Number of cases giving a negative Wassermann reaction and presenting no clinical evidence of the disease 82 or 34.9 Number of cases giving evidence clinically or bacteriologically of the disease 216 or 96.8 Number of cases which gave a clinical history of the disease 209 or 93.7 Number of cases verified by bacteriological examination 159 or 71.3 Number of cases verified by both methods 152 or 68.17 Number of cases examined clinically and bacteriologically which gave no evidence of the disease 7 or 3.1 If only the cases were selected in which it was possible to obtain complete examinations both clinically and by laboratory methods also, these percentages would undoubtedly be much higher.

This factor alone should make us realize the importance of the treatment of such a disease in the community and the necessity for hospitals (as pointed out by the report of the White Slave Commission of Massachusetts) where people could be invited to come for the treatment of this disease as well as for gonorrhoea. At present, as is only too well known, there are very few hospitals where either of these diseases are treated, and it will be remembered that these are the only contagious diseases which have not been made reportable by the Board of Health.
