ing Chosica, since these conditions are inimical to the establishment 

 and persistence of the Phlebotomus, in the vicinity. 



Santa Eulalia, about 3,500 feet, marks the lower limits of the verruga 

 zone of the Rimac valley, and Matucana, about 7,800 feet, marks its 

 upper limits. The Phlebotomus has been found by the writer at both 

 places, and at several intermediate points. It is most abundant at 

 Verrugas Canyon, about 5,300 feet, being abroad there every night 

 in the year. Practically all the Phlebotomus used in these experi- 

 ments were brought from Verrugas Canyon. 



Experiment I 



Cehus capuchinus, male, 2 or 3 years old, from Peruvian montanya. 

 Average temperature under 39°. Kept in laboratory from April 22 

 to October 10. Perfectly normal and healthy, blood normal. On 

 October 10 he was taken to Verrugas Canyon and chained to a tree at 

 east end of house next to stone w^all from which issue the Phlebotomus 

 in large numbers every night, and kept there continuously till Novem- 

 ber 6, when he was returned to the laboratory in Chosica. On many 

 nights spent in Verrugas Canyon by the writer and his assistants, from 

 July 9 to November 6, not a single bloodsucker of any description was 

 seen flying other than the Phlebotomus, and the writer has personally 

 spent the entire night in such search. It is thus quite certain that this 

 monkey was not bitten by any culicid or other night-flying bloodsucker 

 in addition to the Phlebotomus. Blood smear taken October 15 

 showed nothing. Smears taken November 12 and 18 showed Bartonia 

 bodies in small number. Temperatures varied from 39.3° to over 43°, 

 but no high temperature was long continued. Miliar eruption began 

 to appear on orbits November 13, decreasing on November 17. Miliar 

 sore appeared on back of left hand November 18, and one on outside of 

 left foot at ankle. November 21 showed five bleecUng miliar sores, 

 being on left orbit, left hand, left elbow, and both feet, all having 

 scabbed over the following day. For several days these were most 

 typical, with exudation, exactly like miliar eruptive sores commonly 

 seen on legs of human cases. The left orbit, left hand and elbow sores 

 practically dried up November 28, the feet still remaining scabbed for 

 some time thereafter. Later about five sores developed on the back 

 and continued for over three weeks. This Avas evidently the acute type 

 with miliar eruption. 



Experiment II 



Cehus capuchinus, male, about two years, from Peruvian montanya. 

 Admitted to laboratory April 22 with the preceding. Average tem- 

 perature under 39°. Normal weight about 4,500. Perfectly sound
