Describes the unusual appearance of a horse whose mother had previously borne a foal by a quagga. The effect of one mating on the subsequent pregnancy of another mating is explained by JJW using Pangenesis.

CD thinks JJW’s account [in 7137] is significant for a theory of generation and should go to some scientific society; suggests additional data is needed. Quotes cases of subsequent progeny apparently affected by a previous impregnation. Perhaps not prudent to allude to "despised" Pangenesis, which CD fully believes will have its day.
