Writes at Frank Buckland’s suggestion. Can JB provide any information on the proportion of sexes in rats?
Do male rats fight for the possession of the female? Are they polygamous?

To John Bush 2 April [1868]
Summary
Thanks JB for his information. Has heard of analogous cases to JB’s observations on [colours of] crossed rats; the offspring of white and grey mice are stated to be either white or grey and never piebald.
