To J. D. Hooker   [26 March 1868]¹

My dear Hooker

If I do not hear to the contrary I will come to Kew with Lizzie alone (for my wife & Etty are both afraid of the exertion, though they w^d. enjoy it)² on Saturday morning by Train which arrives at Kew at 10^o 40^’ & return by the 12^o 25^’, or possibly 12. 55^’ for my strength will be by that time exhausted by walking & seeing the Hot-houses. Hence we will not accept your invitation for Luncheon.—

If Saturday morning sh^d. be wet, it shall be Monday if not inconvenient to you.—

Yours affect | C. Darwin
