My dear Sir,

Your very kind note was forwarded from London here, and reached me this morning.¹

I should very much like to see the bones etc that you have obtained from Ruthin, and would run over to see the fissure, if you could put me in the way of doing so.² I am staying here for 14 days, after which I return home to

Norman Road, Rusholme, | Manchester, where,

if you will be kind enough to send the remains, I will try to make out the species.

That Ruthin district is very interesting, and ought to furnish large numbers of cave-beasts. The Cefn cave contained the rare R. leptorhinus.³

I am delighted to see how fast Geolog. evidence is being discovered in favor of the ‘Development Theory’. This last week, I read a paper of Prof. Owen’s in which three species of S. American “Hippidian” (Ow) fill up in great measure the blank between Horse and Hipparians   This discovery makes Mr. Gaudry’s genealog of Horse very complete.⁴

The small sketch of the British mammals, (Pleistocene) is very incomplete: but at some future time I hope to fill it in, and to finish the details.⁵

I am | My dear Sir | Yours truly | W. Boyd Dawkins
