A hemoglobin test which was given to the students of the University this year showed that the average among the men was 80.04 per cent, and only 77.6 per cent among the women. The average for Porto Rico should not fall below 85 per cent, and the anemic conditions indicated by the low average is an indication that the disease is to be found not only among the country people, but also among people of the best conditions of life. It will be impossible to settle the economic and social problems of Porto Rico until the question of personal health has been more nearly solved than it is to-day. With a large proportion of the country people sick from anemia and malaria, and with tuberculosis as prevalent as it is at the present time, the weakened vitality will not permit strenuous or continued work sufficient to improve economic conditions to any great extent. Social conditions, depending as they do upon the economic situation, must also be slow of improvement, and the most important work facing the Government of Porto Rico at present is the elimination of such diseases as impair the physical condition of the people and thus interfere with economic and social progress. CRIME GENERALLY speaking, criminals may be divided into three classes: first, those who direct crime but who take no active part in the commission of the crime themselves; second, those who commit crimes which require a considerable amount of personal courage; third, those who commit crimes which do not necessarily involve any great amount of personal courage. There might be added a fourth class, which would consist of those who commit crime through ignorance of the law or carelessness in informing themselves of exact legal measures and in heeding this knowledge when once obtained. During the year 1915-16 there was a total of 53,006 arrests in the Island of Porto Rico. Of this number, nearly 47,000 were men and the rest were women. On the basis of a population of 1,200,000, this would give one arrest for every 22 persons in the Island. Of this total number of arrests, however, only 438 were cases of felony. There were a great many arrests for the infraction of municipal ordinances,--something over 11,000 in all,--and more than 8,000 arrests for disturbance of the peace. Over 9,000 were for gambling, and over 2,000 for petty larceny; about 5,000 arrests were for infraction of the sanitary laws, and nearly 2,000 arrests were for infraction of road laws. This shows that the greater number of arrests was for comparatively unimportant crimes; by unimportant meaning, of course, those crimes which do not directly involve the loss of life or of any great amount of property. The felonies committed during the year were as follows:
