Not surprised incipient disease in female would make her unattractive to male.
Sorry JJW’s official duties are so heavy.
Thanks for new case.
Not very well.
JJW is quite at liberty to use CD’s name as patron of cat show.
Has no doubt he will find JJW’s address interesting.
Thinks same spot for nesting might prove attractive to birds, though they had had no intercommunication.
August Weismann is interested in JJW’s experiments on birds and the caterpillars they eat.
