Summary:

Thanks JSH for his address [Address delivered in the Ipswich Museum on 9th March 1848]. Questions a sentence which implies that only the practical use of a scientific discovery makes it worth while. The instinct for truth justifies science without any practical results. Cites his work on cirripedes.

Summary:

Some geologists (especially H. T. De la Beche) doubt boulders have really been carried above their parent rock, but rather thought they were left behind as a result of denudation. Asks JP’s view of this, which he can quote. Supposes he will be well abused for his paper, but is resolved "not to show a white feather".

Summary:

Pleased at RO’s praise of Coral reefs.

Has read with very great interest RO’s "Report on the archetype" [Rep. BAAS 16 (1846): 169–340]. RO should give name to every letter or number in his woodcuts.

Summary:

Has heard no more news of his paper; shall he write to the R.S.L. for news? Comments on the claims of James MacCullagh for theories regarding light. Hopes to get something published by the London publishers so has written a paper on trigonometry, which he hopes JH will present to the R.S.L. Doubtless JH is aware that there is no general proof for John Napier's rules.
