From J. E. Gray   17 February 1868

My Dear Darwin

Our suspicions relate to the same person I think there can be no doubt, and is he not the great friend of John Murray, did he not induce him to take up Du Chaillu—¹

I suspect the long notice in the Pall Mall is by Sclater but it wants more spirit—²

My paper on Pigs is being printed in the Proc Zool. Soc. 1868.³

I do not see that you make any observation on the colour of the Horse,⁴ I consider that the normal colour of the Horse, differs from that of asses in being Pomelet or coppered that is marked with round pale spots, on a dark ground, these spots are to be seen in grey Black, & bay horses indeed in all horses more or less distinctly, they look like the hammer mark on copper & hence the french & English name

I saw a dappled grey horse defined the other day as horses with round black spot, but that is a mistake   the spot or at least the edge of them is lighter than the ground colour of the coat, the middle of the pale spot is sometimes as dark.

I have never observed any tendency to coppering in any species or specimens of asses⁵

I saw Westwood today   he called the article in the Athenæum as Darwin controverted by Darwin—!!!⁶
