18 Cornwall Terrace, Regent’s Park, N.W.:
Sunday, March 1881.
I have got a lot of cats waiting for me at different houses round Wimbledon Common, and some day next week shall surprise our coachman by making a round of calls upon the cats, drive them several miles into the country, and then let them out of their respective bags. If any return, I shall try them again in other directions before finally trying the rotation experiment.2
I am also getting the experiment on flashing light agoing. The first apparatus did not answer, so now I have invested in a large eight-day clock, the pendulum of which I intend to make do the flashing.3
