and through the hairs along side of fore arm for i minute (i l /2 

 inches) then settled down to feed (2.38 p. m.-2.45) ; blood began to 

 enter the head after 2 minutes (2.40 p. m.) ; abdomen swollen at 2.42 

 p. m. At 2.44^ a red pellet of excrement was exuded from the ab- 

 domen, continuing in a string of a dozen or more, the nymph ceas- 

 ing to feed. To the naked eye, the nymph now appears as a small 

 red conical moving object (thorax and abdomen, alone visible thus) : 

 Removed to vial on piece of cheese cloth. Nymph avoided food when 

 presented to it at 8.23 p. m., 31 st March and though at first attempt- 

 ing to feed when placed on arm, after a minute and a half crawled 

 off. Body still deeply colored. 



At 4.02 p. m., April ist, the nymph went at once to food when the 

 cloth holding it was approached to bared arm; its body pallid, ex- 

 cepting darkness of the alimentary canal. Blood entered at 4.04 p. m. 

 and feeding continued until satisfied at 4.15 p. m. The abdomen then 

 had the appearance of a partially inflated balloon. Toward the last, a 

 minute string of ruby pellets, dry, was slowly exuded from the anus 

 and as slowly dropped; this was capped or headed by a rounded shin- 

 ing dark clot. And again from 10.30 p. m. to 10.43 P- m., April ist, 

 the nymph was fed. Could see no blood enter hut abdomen became 

 swollen, peristalsis strong, but no excrement voided ; taken from 

 food. Placed on food again at 8.44^2 p. m., April 2nd, the nymph 

 then pallid, excepting dark canal ; first blood entered after I minute ; 

 feeding continued until 9.07 p. m. (satisfied) ; anus at first, as usual 

 after first two or three meals, with a round excrementitious cap. 



Placed on again not until 10.21 p. m., April 5th, nymph then very 

 pale, the abdomen shrunken. Commenced to feed at once, causing 

 slight itching. Successful in obtaining blood after 4 1 /, minutes of 

 continuous effort and fed until 10.55 P- m - ; the usual red excrement 

 voided. Feeding stopped by observer, blood not pulsating then, but 

 peristalsis strong and nymph was probably being imbibed. Placed on 

 food again at 9.15 p. m., April 6th, 1910, the nymph pale; blood began 

 to enter after 4 minutes and feeding continued till 9.30 p. m. (by per- 

 mission). . Pulsation of blood stopped at 9.27 p. m. Placed on food 

 again April 7th, 10.48 a. m., the nymph then colored somewhat ; be- 

 gan to probe at once, first blood entering not at all ; none was seen 

 to enter though the nymph was plainly obtaining nourishment, the 

 abdomen swelling and excrement being voided gradually, as usual dur- 

 ing the process of feeding. The voided excrement had the appear- 

 ance of minute blackhcart cherries strung together. Feeding con- 

 tinued until 11.39 a- m -> the nymph being removed. It was then much 

 swollen, the abdomen red. At 6.45 p. m., April /th, it was placed on 

 food but crawled around for five minutes and would not feed. Re- 

 placed in vial.
