462 Life and Letters of Francis Galton 



Send inc some "cousin" circulars that I may distribute. I heard of them at Bradford. My 

 antecedents of scientific men is fairly in hand. Out of the 186 asked, between 120 and 130 

 have either sent or promised. I have about 80 in hand now. 



Are you quite sure Hadley of St John's is a relation. Miss Parker's* eldest daughter married 

 Mr Hadley (there was one other daughter who died unmarried) and had one son, l)r Henry 

 Hadley, and one daughter who died unmarried. Ever very sincerely, Fkancis Galton. 



To George Darwin, Esq.

Miss Parker ultimately married a Mr Day and had two or three children, of whom one 

 daughter turned out very ill.

My dear George, I also quite forgot about your maps till just after you went; but 

 Gen. Strachey is the man. He has the thing in his hands and I am only an occasional assessor. 

 It is the framework that gives the difficulty. He had, at last, two great machines constructed 

 down in the Isle of Dogs, by an Engineer who makes bridges and the like for his department. 

 They were both heavy and crooked. I went down with him and we suggested a much amended 

 plan of which he sent me the working drawings but my illness has prevented my seeing him 

 since. The immediate object is to produce two frames, 10 ft. diameter, that can go in a cab or 

 be sent by luggage train and yet be easily mounted in the lecture room. The great point is to 

 have them as the regular maps at the British Association at Bristol next year, when Strachey 

 may be counted on as being elected President of the Geography Section. You had better write 

 to hiin and keep at him periodically, and whenever I see him I also will "nag." 



Thanks greatly for your bits of criticism, they are all valuable to me and helpful. I am 

 gratified to hear that your Father is interested in the book. 



Henry Parker J is not wholly my fault; the entry in your Father's schedule is "distinguished 

 classic, and good artist and chemist." I quite see now that the last half of the sentence was 

 intended to be amplificatory, merely for my own information, but it happened to chime in with 

 some vague recollection I had of his having occupied himself much with chemistry and I did 

 not inquire further but put in the "chemist" (or whatever the exact phrase was — my book is 

 not at hand). 



* Miss Parker was the mother of two natural daughters of Erasmus Darwin: see Vol. I of 

 this Life, p. 17 and Plate X. The surgeon with the spurs is Hadley. 



f The Hadleys of St John's College, Cambridge were distinguished mathematicians, and 

 the problem was, and remains, whether they were related to the Darwins. Sister Emma's 

 diaries continually refer to the Hadleys. But the pedigree of the Derby Hadleys has not yet 

 been ascertained.
