To Feed Mosquitoes on Birds, etc. 
1. Prepare a framework of wood and cover two 
sides with cardboard and two with netting. Cover 
one end with netting drawn tight, and to the other 
attach a 4 sleeve 5 of netting. Catch or breed out a 
number of Culex ( e.g ., Culex fatigans ), and place in the 
frame. Keep the frame in a dark place, and place a 
saucer of water in it. 
Before placing the bird in the cage, a small bag 
of netting should be tied around its head, as it then 
remains perfectly quiet, and further, the legs may be 
fastened. Small birds, such as sparrows, should be 
carefully treated, as, otherwise, they are very liable 
to succumb. Pigeons should be treated in the same 
way, if necessary. 
2. Mosquitoes may be fed singly on pigeons 
and other large birds by placing the end of the test 
tube, in which the mosquito is confined, against an 
area of skin free from feathers, e.g ., under the wing. 
Feeding Experiments on Birds 
1. Feed a number of Culex , e.g., C. fatigans , on 
sparrows (in which have been detected Proteosoma in 
the blood), by placing these for a time in the mosquito 
cage. 
After feeding for one or two days, place those 
mosquitoes, which have fed and are gorged with blood, 
in a prepared jar, and keep until ready for dissection. 
Note the zygotes of Proteosoma which generally 
occur in large numbers in the stomach wall, and in 
which very coarse and dark pigment is seen. 
2. Feed some Anophelines on Proteosoma spar¬ 
rows, and note that no zygotes are formed.
