hookworm, Trichuris, and both of the amoebae. We consider it 

 likely that the elevation of his eosinophilia from 11 to 33 per 

 cent was an expression of a cumulative effect, resulting from 

 the persistence of his hookworm infection. A similar condition 

 is presented by the next case. 



Prisoner 57345. — Aged 36 years. Laborer. Personal history and phys- 

 ical examination not significant. Blood examination before treatment: 

 3,900,000 erythrocytes; 35 per cent haemoglobin; 9.5 per cent eosinophiles. 

 Blood examination 2 months, 15 days after treatment: 4,730,000 erythro- 

 cytes; 90 per cent haemoglobin; 31 per cent eosinophiles. Weight advanced 

 4.7 kilograms. On screening the stools after treatment, 32 Ancylostoma, 

 271 Necator, and 1 Trichuris were recovered. He received 6.2 cubic cen- 

 timeters of carbon tetrachloride. 



Like the preceding subject, this man's fasces still contained ova 

 of hookworm and Trichuris on examination, two and one-half 

 months after treatment. His eosinophilia had increased from 

 9.5 per cent to 31 per cent; but, as shown above, he had increased 

 substantially in weight. 



Prisoner 14726. — Aged 30 years. Laborer. Personal history and phys- 

 ical examination irrelevant. Blood examination before treatment: 

 4,050,000 erythrocytes; 45 per cent haemoglobin; 1.5 per cent eosinophiles. 

 Blood examination 2 months, 3 days after treatment: 5,700,000 erythro- 

 cytes; 95 per cent haemoglobin; 12 per cent eosinophiles. Weight declined 

 4.4 kilograms. On screening the stools after treatment 23 Ancylostoma 

 and 77 Necator were recovered. He received 8.9 cubic centimeters of 

 carbon tetrachloride. 



On reexamination of the fasces of this subject, two months 

 after treatment, he was found still to be infested with hook- 

 worm and Trichuris. 



For the reasons already stated, we refrain from any detailed 

 discussion of the weights of these and the other men in the 

 series, but as a point of general interest we present a few figures 

 in connection with the eighty-eight men who were weighed both 

 before and after treatment. 



Weights were taken after periods ranging from 2 months, 4 

 days to 3 months, 21 days after treatment. 



A gain in weight was recorded in fifty subjects, and a loss in 

 thirty. Eight of the men showed no change in weight. 



The maximum increase in weight, 10.4 kilograms, was re- 

 corded in a man who was infected with hookworm, Ascaris, and 

 Trichuris. When examined before treatment, on June 22, 1922, 

 his chest revealed crepitant rales and impaired resonance. His 

 condition was unchanged on September 1.
