ii8 THOMAS HENRY HUXLEY 



form of geological and archccological observations, and 

 a careful study of literature for and against the pseudo- 

 miracles of Lourdes. His travelling companion was 

 Hooker. One outcome of the holiday was the publication 

 by the latter of observations on glaciation in central France 

 (Nature, xiii, p. 31), though it afterwards turned out 

 that the results had been anticipated by others. The 

 trip ended in Switzerland and South Germany. 



Those who crave for personal details will be interested 

 to know that during this tour Huxley consumed a 

 reasonable number of cigars. Hooker had previously 

 (1867) introduced him to cigarettes, as an antidote for 

 gastric disturbance. A somewhat ardent devotion to 

 " my Lady Nicotine " ultimately culminated in the pipe 

 (1875). The practice, however, was primarily thera- 

 peutic, for Hooker says (Life, i, p. 393, foot-note) : — 



*' I have never blamed myself for the ' teaching him ' to 

 smoke, for the practice habitually palliated his distressing 

 symptoms when nothing else did, nor can his chronic illness be 

 attributed to the abuse of tobacco." 



The present writer, however, does not propose to 

 promote the sale of one or more brands, by mentioning 

 them here. 



Among other fresh duties undertaken were those 

 connected with his appointment as a Governor of Owens 

 College, which institution was opened in the autumn. 

 Much time was taken up in connection with the Royal 

 Commission on Scientific Instruction, etc. 



Some of Huxley's essays were collected and published 

 this year under the title of Critiques and Addresses. 

 Though very largely read this never attained the extreme 

 popularity of Lay Sermons {cf. p. 1 05). An essay en- 

 titled "Problems of the Deep Sea" was put out in 1873
