Ch. II.] CAMBKIDGE. 21 



can remember the exact appearance of certain posts, old trees 

 and banks where I made a good capture. The pretty Panayseiis 

 crux-major was a treasure in those days, and here at Down I 

 saw a beetle running across a walk, and on picking it up 

 instantly perceived that it differed slightly from P. crux-major, 

 and it turned out to bo P. quadiipunctatus, which is only a 

 variety or closely allied species, differing from it very slightly 

 in outline. I had never seen in those old days Licinus alive, 

 which to an uneducated eye hardly differs from many of the 

 black Carabidous beetles ; but my sons found here a specimen, 

 and I instantly recognised that it was new to me ; yet I had 

 not looked at a British beetle for the last twenty years. 



I have not yet mentioned a circumstance which influenced my 

 whole career more than any other. This was my friendship 

 with Professor Henslow. Before coming up to Cambridgo, I 

 had heard of him from my brother as a man who know every 

 branch of science, and I was accordingly prepared to reverence 

 him. He kept open house once every week * when all under- 

 graduates and some older members of the University, who were 

 attached to science, used to meet in the evening. I soon got, 

 through Fox, an invitation, and went there regularly. Before 

 long I became well acquainted with Henslow, and during tho 

 latter half of my time at Cambridge took long walks with him 

 on most days ; so that I was called by some of the dons " the 

 man who walks with Henslow ; " and in the evening I was very 

 often asked to join his family dinner. His knowledge was 

 great in botany, entomology, chemistry, mineralogy, and geo- 

 logy. His strongest taste was to draw conclusions from long- 

 continued minute observations. His judgment was excellent, 

 and his whole mind well-balanced ; but I do not suppose that 

 any one would say that he possessed much original genius. 



He was deeply religious, and so orthodox, that he told me 

 one day he should be grieved if a single word of the Thirty-nino 

 Articles were altered. His moral qualities were in every way 

 admirable. He was free from every tinge of vanity or other 

 petty feeling ; and I never saw a man who thought so little 

 about himself or his own concerns. His temper was inrperturb- 

 ably good, with the most winning and courteous manners ; yet, 

 as I have seen, he could be roused by any bad action to the 

 warmest indignation and prompt action. 



* The Cambridge Bay Club, which in 1887 attained its fiftieth annivcr- 

 Bary, is the direct descendant of these meetings, having been founded to 

 fill" the blank caused by the discontinuance, in 1836, of Henslow's Friday 

 evenings. See Professor Babington's pamphlet, The Cambridge Bay 

 Club, 1887.
