Description:‘My dear Shute,
Just a line to let you know how the Anopheles material went. The egg laying was very successful practically every insect laying so that I got a very good series and some small larvae to rear. Whether the fixation I used is good for the [illeg.] plates I don’t know. I think one may have to do something more drastic. At any rate I should think the later stages may be quite good. The larvae were not very successful. Though I carried them all the way in my hand there were a good many deaths (I suspect these possibly pupating) and for some reason the remaining larvae did not come through very well though I had [illeg.] I thought quite good conditions. However, another generation is coming on slowly. I saw adult maculipennis on the ceiling of the lower room in the hotel & at night but very little to be found in the ditches &c. Perhaps I haven’t got the right conditions in mind. Most of the ditches here are flag filled with rather clean water often running. I imagine some ponds are better but hope to create something eventually. I got some pupae from the larvae but very small and a great many larvaes seemed to linger without doing anythin and then die. Mindful my breeds need better conditions. Very many thanks for all your kindness.
Yours sincerely,
Sir R. Christophers.’
