Is it fair to take advantage of knowing that Wallace is in the field? Seems hard on CD to lose priority of many years, but does not feel this alters justice of case.

Baby [Charles Waring Darwin] has much fever. Frightened because three children in village have died from scarlet fever.

Intends to set up a meeting with appropriate members of the B.A.A.S., in order to prepare presentation about magnetic observatories for the B.A.A.S. meetings in Leeds.

Responds to GA's 1858-6-25, and essentially agrees with GA's assessment.

Profoundly sorry for Lane.

Thanks WDF for facts about call ducks, pigs, and Leicester sheep.

Has been observing and experimenting on the construction of bees’ cells. Thinks he has a theory which simplifies the problem.

Scarlet fever in family; nurse ill.

Death of Charles Waring Darwin [1856–8] from scarlet fever.

JDH’s and Lyell’s kindness [presumably about A. R. Wallace’s letter]. CD can provide a copy of his letter to Asa Gray [about CD’s species theory].

JDH wants papers at once. CD sends Wallace’s paper and CD’s abstract of his letter to Asa Gray. Sends [species] sketch of 1844 with JDH’s notes to assure JDH he had read it.

Supports JH's intentions [see JH's 1858-6-26] and Edward Sabine's proposals about magnetic observations, but displays little faith in the effectiveness of the B.A.A.S.

Communicate papers by CD and A. R. Wallace on "The Laws which affect the Production of Varieties, Races, and Species". Explain that CD and Wallace have, independently and unknown to each other, arrived at the same theory to account for the appearance and perpetuation of specific forms, and that neither has yet published, although CD first sketched his theory in 1839. Give their reasons for arranging the joint presentation.
