Congratulations on George’s attaining Second Wrangler.

Variation has just arrived. Wishes he had two heads or a body that needed no rest.

Thanks JMH for his congratulations.

Recalls gift of microscope [from JMH in 1831]. [See 99].

Thanks for congratulations.

Still thinks THH has been too "sharp sighted" on hybridism.
