Dear Darwin

My wife presented me with a huge girl last night—said to weigh 11 lbs both are doing as well as possible. I read the Psychological book of Brodies during the operation & found a good many curious facts new to me with a redundancy of old ones. All would probably be old to you.

Will you oblige me with you ideas of what constitutes highness & lowness in the Animal Kingdom! Eg. in plants I should say that a high developement in the scale is indicated by special adaptation of organs to the discharge of functions & great deviations in those organs from the type upon which they are constructed. Thus Ranunculaceæ are low in the scale because the floral organs are apt to run into one another & revert to the type (a leaf) on which they are constructed—because calyx & corolla are so often alike— Stamens often reverting & the follicles present little deviation from a leaf folded on itself.— Hence monopetalous flowers are higher than polypetalous, inferior ovaries a higher type than superior &c &c. Dicotyledons than Monocot. Exogens than Endogens, &c. &c.

I hope your dinner did not disagree with you. I had to walk to Shoreditch next morning no cabs!

Ever Yrs | J D Hooker

    After ‘great’, Hooker had written and then deleted: ‘*deviation from [above del ‘modification of'] the type upon which those organs are constructed, in’. For CD's views on this subject, see letter to J. D. Hooker, 27 [June 1854].
