Rejoices that "Lagrange’s case does not seem very bad".

CD is working hard at dissecting Thalia. Has recovered some handiness with microscope.

Thanks GHD for his drawings [of Thalia]. Some parts need attention.

Summary

Writes to say that the point on which he thought GHD’s drawings were mistaken proves to be an error in his own observation.

He and Emma rejoice that GHD’s mathematical troubles are at an end. It is miraculous that he unconsciously followed the right course – like composing a sonata by a fluke.

Summary

Rejoices that he should have "staggered" William Thomson so quickly and that the latter should speak of GHD’s "discovery". The internal heat [of the earth] will please geologists and evolutionists.

Summary

Forwards pamphlet (Jules Carret 1878) to GHD.

Summary

Delighted with [William Thomson’s] report. "There can be no doubt now about the value of your work." CD has "not been so much pleased for a long time".
