My dear Sir

Very many thanks about Owls' eggs, for your note, & nice little Treatise.— I am sorry to hear that the cylindrical cells are mislaid, for I shd have very much have liked to have examined their bases or point of attachment.—

My object in writing now is to know whether you often examine your Hives & slides.— If you do, & shd stumble on the very first commencement of the comb, I shd excessively like to see it. Huber says that first, a very thin & very low littleridge is made; & then one one face the base of a single cell is hollowed out, &on the opposite face, the bases of two cells. He states that first the outlines ofthese 3 primordial cells are arched, (section [DIAGRAM] ) & then made angular ( [DIAGRAM] ).

Now what I what I want so much to see is this rudiment of the comb in this state. I believe when the arched bases of the cells are made angular, the bases of other adjoining cells have just been commenced. The hexagonal tube or prism has not been at this period hardly been begun; & all must be very minute. Will you kindly aid me if you can, in this respect; though I can plainly see that it is very improbable that you can, for it wd require incessant watching or a rare piece of good luck.

I shall not be able to begin on my M.S on Pigeons for a fortnight yet.— This note requires no answer, & I know how busy you are.

My dear Sir | Yours sincerely | C. Darwin

    F. Huber 1814, pp. 141–3. CD's annotated copy of the work is in the Darwin Library–CUL. CD made many notes on these pages, questioning François Huber's description of the construction of bees' cells. See also letter to W. E. Darwin, [26 May 1858].

    In a note headed ‘May 8/1858 Opened Straw Hive of Mr Innes.’ (DAR 48 (ser. 2): 22), CD described his observations of the shape of the bases of bees' cells, stating, in part: ‘The attachment of comb very irregular to Hive: I cd detect the pentagonal upper cells: but the bases were in all cases *slightly concave, or sub-angular or [interl] flat & irregular. *They are not perfectly angular.
