My dear Darwin

I doubt not you are very busy & I shall therefore be brief in answers to your last.

There are not more than two numbers to all the Gal. collection that I can find. I have often tried to make your notes hinge on to the species. I wish you would come & take a look at them before I return them to Henslow. “Cosmos” came all right, I am quite annoyed at your binding it, but obliged truly all the same. Please send back my things for Humboldt by bearer, or else to Hiscock’s Kew boat Hungerford Stairs or by P. Deliv. Coy, not by Steamer.

What on earth do you want to buy Webbs Geograph part of Canary Islds for.?² I had rather you kept mine altogether I can no more use it now than I can 2 pair of spetacles; you may really & truly keep it altogether if you will. I have my Father’s copy here. Would you like his historical & Anthropological portion Zoology &c..?—

I cannot make out that Sandwich Isld have any thing of an Alpine Flora, there are I know a few alpine things but nothing to what 12000 ft should give. I expect the higher regions are desperately barren, bad soil earthquaquey perhaps &c.— Terra del Fuego at 56^o has no alpine Flora that I could make out, or next to none, I diligently explored the hill tops, 1000–1700 ft.³

I think the climate of Tasmania infinitely more xcessive than New Zeald. but am no Meteorologist, if any one would calculate them I have lots of Tasmanian temperatures

I hope never again to call ♂ flowers sterile. Botanical nomenclature is quite a science per se & you must be forbearing with us, we having nothing familiar like stomachs nerves eyes &c to talk of & by; all is a new language I will pay particular attention to your most val. hints especially as coupled with such pretty comps. The Plates are all done by M^r. Fitch except the Dissections, which are almost invariably my own, copied by him on the stone.⁴

Could we arrange to turn over the Gal. plants together,?— I fear you are come to Town on your health & dread bothering you. Henslowe is to be in Town Friday & I intended returning them then to him, he will be at 44 Queen Square Bloomsbury on Saturday.

Ever yours most truly | J D Hooker

PS. I append a few comparison of what I took as standards of excessivity in climates. V. D. L & London are tolerably close, I wish I had New Zeald. I used to calculate that mean of Max & Min differences of the months, of the days & of each day (I think) gave tolerable results. I am rather confused now

P.S. I have 9^AM, 3^PM, 9^PM temps. throughout our cruize including 8 Months at Tasmania & 4 at New Zeald., or rather my dear delightful Capt R. has them all⁵ but a very few scattered results I amused myself working out of V. D. L. & London. diag Sept V D L. March London
