accuracy of measurements of distances, depths, and angles. 

 A section to Mm was no sketch unconsciously modified to 

 tally with hypothesis : it must be a portrait. This lesson 

 lias stayed with me. In that study, that eventful night, I saw 

 my first palaeohthic implement (exhibited). Tylor taught me to 

 use theodolite, level, and chnometer ; his books and specimens 

 were at my disposal, and patiently he led me over all the 

 ])leistocene and recent beds of the Thames valley, and these 

 and those of Northern France I carefully examined, levelled 

 for him or with him. Alfred Tjior was both geologist and 

 anthropologist, but the lustre of Sir Edward his younger 

 l)rother"s name has overshadowed the fame of the greater 

 Alfred. Only in one way, save in love, could I recompense 

 him : I dedicated my '' Physical System of the Universe' to 

 him, and, good simple soul, he used to carry a copy of it about 

 with Mm and show iolka the title-page ; and when DarAvin 

 and Wallace wrote congratulating me he was if possible more 

 ]ileased than I was. For more than two -score years the winds 

 have sung a requiem through the oak-leaves over his grave, 

 and I have grown old and widowed ; but in dreams each 

 mght as I press my lonely pillow , two faces come to me. my 

 sweet wife's and Alfred Tylor's. and when in the not distant 

 years I too am but a shade I fain would that some of ni}^ 

 friends may carry kindly memories of me, if but in dreams. 



Largely through Alfred Tylor"s influence I had the 

 inestimable advantage of spending a year as Librarian and 

 Diagram-maker at the Geological Society. Here I made the 

 acquaintance of the great founders of Geology — Sedgwick — 

 PhiUips, MurcMson, and above all of Sir CTiarles LyeU, the 

 true father of modem geologj^, the founder of the Tertiarj- 

 system, the great expounder of the action of existing forces, 

 tlie inspirer of Darwin. Lyell was very good to me, and used 

 to come, ask in Ms immitably modest way if I could spare a 

 httle time for a chat ! Fancy it I Spare time ! I could have 

 sat at Ms feet a lifetime. He used to teU me all Ms early 

 struggles to drive out the perniciously convement cataclysms 

 and convulsions of nature that accounted so easily for cHff 

 and gorge and contorted rock. His pMlosopMcal brain poured 

 out to me of its vast stores, and warned me of many pitfalls, 

 many a cul-de-sac in reasomng. To Lyell, next to Alfred Tylor, 

 I am in grateful bondage still : they can never be repaid. 



At the Geological Society I acquired a thorough knowledge
