D. A. Spalding has asked for information to help with his experiments on sense of direction in animals. Has arrived at same results as GHD with blindfolded children. Will GHD let him have his results?

CD has forwarded proofs of Descent [2d edition]. Urges GHD not to work on them if his poor health makes them too tiring.

Thanks GHD about Spalding [i.e., for responding to Spalding’s request, see 9472].
