The third and last part of the Geology [South America] will be published in a few days. Apologises for not sending JSH the other volumes.

Has attended Southampton [BAAS] meeting.

GP has been asked to recommend a naturalist to sail with Capt. Robert FitzRoy to Tierra del Fuego and the South Sea Islands. If Leonard Jenyns is not available, whom would JSH recommend?

P.S. Urges JHS not to lose this opportunity to have collections made for "our museum".

JSH has been asked by Peacock to recommend a naturalist as companion to Capt. FitzRoy on Beagle voyage. CD the best qualified person; not a finished naturalist but amply qualified for collecting, observing, and noting.

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.

Criticises lecturing system in education and emphasis on classics. Has forgotten all his classical knowledge.

Asks JSH’s help in naming cirripedes, on which he is working. Believes he has made "some very curious points".

Expects a sixth child [Francis] in August.

Describes the Birmingham meeting [1849] of BAAS.

His health is poor. Continues with water-cure with considerable benefit.

Thanks JSH for information and suggestions on benefit clubs,

and for a shipment of fossil cirripedes.

J. B. Innes is greatly obliged for JSH’s letter. JSH’s observation of chalk flints strikes CD as "very curious".

Announces birth of his fourth son, Leonard.

Gives CD directions for sending him specimens from Beagle.

Writes of Cambridge politics.

Sends cirripede specimens for Ipswich Museum.

Asks how much a village fireworks display would cost.

Comments on the need in education for good habits of expression and accurate observation instead of making "wretched Latin verses".

Is sending plates for R. T. Lowe’s paper [Trans. Cambridge Philos. Soc. 4 (1833): 1–70].

Adds advice on working the surd.

Agrees with CD that Beagle voyage would have been wrong for Jenyns, but assures him he (CD) is the right man. Warns CD against his "foible" of taking offence at rudeness or ungentlemanlike behaviour.

CD has been reassured about his "speculation" in Mr Warren’s company. Thanks JSH for his advice and trouble.

Would like to meet JSH in London.

News of Cambridge: the recent examinations; memorial tablet for Marmaduke Ramsay.

Acknowledges a list [of plants?].

Looks forward to new edition [of British plants growing wild in the parish of Hitcham, Suffolk, 2d ed. (1855)].

JSH should not trouble about Anacharis until he is less busy. Will send cirripedes.

Thanks JSH for Anacharis which is flourishing.

P. H. Gosse told him he had several sea animals and algae living in artificial sea-water for over 13 months.

Asks whether JSH considers Lychnis diurna and L. vespertina species or varieties.

Asks for help with his work on hybrids.

Would like JSH to go over London catalogue of British plants, marking "close species", i.e., those he considers real species but which are very closely allied. Withholds his motive as it might influence the result.

Has found Agrostis with worms in every germen and no stamens on stigma.

Now has 46 kinds of peas all growing together.

Red and white campions: JSH regards them as races, not species; a flesh-coloured intermediate exists.

Sends a list of plants with stamps to pay the Hitcham girls who will collect seeds for him.

Describes his work with seeds in salt water.

For his experiments he would like seeds collected from plants that grow both near Hitcham and in the Azores.

Explains again what JSH should do in marking "close species".
