 trouble to the best and kindest of wives and good dear chil- 

 dren is dreadful." 



The minor works in this year were a short paper in the 

 'Natural History Review ' (N.S. vol. iii. p. 115), entitled *'0n 

 the so-called Auditory-Sac of Cirripedes," and one in the 

 ' Geological Society's Journal ' (vol. xix), on the " Thickness 

 of the Pampsean Formation near Buenos Ayres." The paper 

 on Cirripedes was called forth by the criticisms of a German 

 naturalist Krohn,* and is of some interest in illustration of 

 my father's readiness to admit an error. 



With regard to the spread of a belief in Evolution, it could 

 not yet be said that the battle was won, but the growth of 

 belief was undoubtedly rapid. So that, for instance, Charles 

 Kingsley could write to F. D. Maurice \ : 



" The state of the scientific mind is most curious ; Dar-

 the mere force of truth and fact." 



Mr. Huxley was as usual active in guiding and stimulat- 

 ing the growing tendency to tolerate or accept the views set 

 forth in the * Origin of Species.' He gave a series of lectures 

 to working men at the School of Mines in November, 1862. 

 These were printed in 1863 from the shorthand notes of Mr. 

 May, as six little blue books, price 4^. each, under the title, 

 *Our Knowledge of the Causes of Organic Nature.' When 

 published they were read with interest by my father, who 

 thus refers to them in a letter to Sir J. D. Hooker : — 



" I am very glad you like Huxley's lectures. I have been 

 very much struck with them, especially with the ' Philosophy 

 of Induction.' I have quarrelled with him for overdoing 

 sterility and ignoring cases from Gartner and Kolreuter about 



* Krohn stated that the structures described by my father as ovaries 

 were in reality salivary glands, also that the oviduct runs down to the ori- 

 fice described in the 'Monograph of the Cirripedia' as the auditory 

 meatus.
