204 EVOLUTION [CHAP. Ill 



To John Lubbock (Lord Avebury). 



Cliff Cottage, Bournemouth, Sept. 5th [1862]. 



Many thanks for your pleasant note in return for all 

 my stupid trouble. I did not fully appreciate your insect- 

 diving case l before your last note, nor had I any idea that 

 the fact was new, though new to me. It is really very inter- 

 esting. Of course you will publish an account of it. You 

 will then say whether the insect can fly well through the air. 2 

 My wife asked, " How did he find that it stayed four hours 

 under water without breathing ? ' I answered at once : 

 " Mrs. Lubbock sat four hours watching." I wonder whether 

 I am right. 



I long to be at home and at steady work, and I hope we 

 may be in another month. I fear it is hopeless my coming 

 to you, for I am squashier than ever, but hope two shower-

I heard from Lyell the other day in the Isle of Wight, and 

 from Hooker in Scotland. About Huxley I know nothing,

 yesterday, " If every one would kill adders they would come

1 " On two Aquatic Hymenoptera, one of which uses its Wings in 

 Swimming." By John Lubbock. Trans. Linn. Soc., Vol. XXIV., 1864, 

 pp. 135-42. [Read May 7th, 1863.] In this paper Lubbock describes a 

 new species of PolynemaP. natajis which swims by means of its 

 wings, and is capable of living under water for several hours ; the other 

 species, referred to a new genus Prestwichia, lives under water, holds 

 its wings motionless and uses its legs as oars. 



2 In describing the habits of Polynema, Lubbock writes, " I was 

 unfortunately unable to ascertain whether they could fly " (loc. cit., 



P- 137).
