Please accept his grateful thanks for his comments on Mr. Thornton's squaring of the circle. Will send these comments on to Thornton.

Regrets he was out when JH's son called, but has sent him a card for Saturday. Pleased to hear that JH supports RM over his David Livingstone appeal. Suspects that Livingstone will turn up after a year.

Is bewildered in his old age by the new theories of James Croll on the glacial epochs. What does JH think of these theories? Sees no proof of glacial action in Paleozoic times.

Is grateful for a copy of 'Spaziergang' in Latin verses. Envies JH's varied accomplishments. Fourth edition of his Siluria will be issued in October. Relates how James Croll was appointed a geological surveyor in Scotland.

Thanks for kind reply and favorable opinion on his Geometry. Arthur Cayley also expressed a favorable opinion on his writings. Would like a testimonial from JH for the Chair of Mathematics at Cork.
