Offers to send green insects that give off a powerful odour of napthalene.
Sends a drawing [missing] of alleged fossil man found in Colorado. JM is certain it is a hoax perpetrated by P. T. Barnum. It was designed to conform to CD’s well-known views of man’s ancestor.
Sends his paper ["Die selbst-sterilität des Roggens", Landwirtsch. Jahrb. 6 (1877): 1073–6] on self-sterility in Secale cereale. AWR was wrong in claiming Beta vulgaris was perfectly self-sterile.
Reports results of crossing wheat varieties. In the first generation offspring are always uniform; some are intermediate, some resemble one parent. In the second generation, on the contrary, he got a diversity of parental and intermediate forms.

JCC and his young daughter have observed that blossoms of Drosera rotundifolia open in afternoon, which contradicts Forms of flowers.
Thanks for Origin, 6th ed.
