one specimen in a little puddle, not more than four inches deep, which must, 
I am sure, have been as dry as bone ten days before, for we had a long period 
of hot, sunny weather, as you will remember, in the middle of June, 
On the 20th of July I went again to the place already mentioned, at 
Chowpatty,and found the pools dried up, but there was a long, narrow 
ditch, with a little water in it, filled with rotting vegetation and covered 
with an oily film, and in this I found plenty of Culex larve and a few 
Anopheles, On the 23rd of July I found Anopheles larve in the 
Wellington Fountain, opposite the Sailors’ Home. I may mention that, at 
this time, both the fountains (Frere and Wellington) were nearly empty. 
They generally contained just an inch or two of water, kept up by occa- 
sional showers, The bottom and sides were covered with a green, slimy 
growth. One of them swarmed for a time with tadpoles, but there was 
little insect life in them, On the 24th I brought home a large number 
of Anopheles eggs from the Wellington Fountain and tried to rear them. 
The result will be mentioned afterwards. On the 17th of August I went 
to Chowpatty again and got a number of Anopheles larve in a pool which 
had almost dried up. It contained, in fact, little else than fluid mud, with 
an iridescent film on the surface, On the 26th of August I found larve 
swarming in the Frere Fountain, which had run almost dry and had been 
filled again a few days before. On the 14th of September I went with 
Mr, Leask and Dr, Venis to Malabar Hill and explored the stream below 
the reservoir. Since I found Anopheles here at the beginning of the 
year, 2 narrow masonry channel had been made to carry off the water 
and prevent it forming puddles, but this had not yet been carried right 
up to the reservoir, so that there was still the upper portion of the stream 
in its original state, trickling slowly among short grass and forming clear 
pools at intervals. Even where the masonry channel had been made there 
were many such pools at the sides of it, formed by water oozing out of 
the side of the hill. Here we found Anopheles larve in incredible numbers, 
I had never found them so abundant before. At the same time they 
began to swarm in the Wellington Fountain, I took up a hundred or more 
at one dip of my little net. From that time till now I have never failed 
to find them in that fountain. It was repaired some time ago and has 
been kept full ever since, which is decidedly against the mosquito, but the 
green Fucus, which grows on the bottom and sides, often gets detached under 
the influence of sunlight and floats on the top in masses, and in these the 
eggs are laid and the larve thrive. In the Frere Fountain, which has also 
been repaired and kept full, I have not found larve for some time, but 
I have not visited it so regularly. 
In conclusion, I may mention that I found the larve plentiful at Chow- 
patty on the 23rd of October,
