To J. J. Weir 17 March [1870]
Summary
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.
