All these men, before entering the prison, lived on the staple 

 diet of the country — fish and rice — and probably not too much 

 of either. It is scarcely necessary to add that their surroundings 

 were insanitary and their manner of living distinctly unhygienic. 

 Within the prison, however, their entire mode of life was 

 changed. They received a simple but well-balanced ration, 

 which included a liberal allotment of meat, in which most of 

 them had not habitually indulged in the past. Their hours of 

 work and rest were regular, and they were put through setting-up 

 drills and allowed time for healthy recreation. Moreover, their 

 surroundings were strictly sanitary. Under such circumstances 

 it is a little difficult to make any general statement respect- 

 ing the effects of treatment on men who originally were below 

 par physically. 



In illustration of this point we present the protocols of the 

 two subjects who were not infested with hookworms. 



Prisoner 13112. — Aged 48 years. Laborer. Symptoms of pulmonary 

 tuberculosis. Microscopic examination before treatment showed ova of As- 

 caris and Trichuris. Blood examination before treatment: 4,220,000 ery- 

 throcytes; 80 per cent haemoglobin. Blood examination 3 months 20 days 

 after treatment: 4,750,000 erythrocytes; 95 per cent haemoglobin. Weight 

 advanced 2.2 kilograms. No worms were recovered on screening the stools 

 after treatment. He received 8.7 cubic centimeters of carbon tetrachloride. 



Prisoner 19189.— Aged 38 years. Laborer. Tubercular involvement of 

 lungs. Microscopic examination before treatment showed ova of Trichuris. 

 Blood examination before treatment: 4,950,000 erythrocytes; 65 per cent 

 haemoglobin. Blood examination 3 months, 16 days after treatment: 

 4,500,000 erythrocytes; 90 per cent haemoglobin. Weight declined 2.2 

 kilograms. No worms were recovered on screening the stools after treat- 

 ment. He received 6.9 cubic centimeters of carbon tetrachloride.

Prisoner 14646.— Aged 18 years. Laborer. Personal history and phys- 

 ical examination yielded nothing of importance. Microscopic examination

 before treatment: 5,040,000 erythrocytes; 80 per cent haemoglobin; 18.5 

 per cent eosinophiles. Blood examination 3 months 16 days after treat- 

 ment: 5,000,000 erythrocytes; 97 per cent haemoglobin; 3.5 per cent 

 eosinophiles. Weight advanced 0.9 kilogram. On screening the stools 

 after treatment 9 Necator and 4 Ascaris were recovered. He received
