Letter to James Cossar Ewart from Philip Lutley Sclater, 15 February 1901
Sclater answers Ewart's question about experiments in inbreeding in the Zoological Gardens. He states that, while that no experiments specifically based on inbreeding have been carried out at the Gardens, they are careful to inject new blood into their breeding programmes, to sustain the size, health and reproductive powers of the animals.
Letter to James Cossar Ewart from Philip Lutley Sclater, 18 February 1901
Sclater answers Ewart's question about breeding between brothers and sisters of the same breed of animal, stating they tend not to continue breeding well after a few years. He suggests that any breeding experiments would be better conducted in a quieter place than the Zoological Gardens.
Letter to James Cossar Ewart from Samuel Boase, 19 September 1899
Boase congratulates Ewart on the work documented in the Penycuik Experiments. He goes on to discuss the importance of inbreeding in organic evolution in the animal world. He encloses a paper he wrote on inbreeding, which he presented to the Torquay Natural History Society in 1895.
Letter to James Cossar Ewart from William Walls, 14 May 1910
Walls informs Ewart that the black and tan rabbits he sent to him are inbred. He confirms that his black and tan doe had a litter by a wild buck before having another litter to a black and tan buck, and that the second litter bore no relation to the first.
