The work of the earlier part of 1 862 was accomplished 

 under the disadvantages entailed by very indiiFerent health, 

 though fortunately some improvement resulted from 

 a July trip to Switzerland with Tyndall. Part of the 

 duties carried out in the second half of the summer were 

 also of out-door character. For as a member of the 

 Fishery Commission (the first of many Commissions on 

 which he afterwards served), dealing with the herring 

 question, he spent some weeks on the Scottish coast for 

 the purpose of observation and inquiry. 



In the autumn, too, he entered into the full duties of 

 the Hunterian Professorship at the College of Surgeons, 

 thus having to give some twenty-four lectures on com- 

 parative anatomy instead of twelve. This involved a 

 vast amount of dissection, mostly done in the evening, 

 for Huxley was never content to rely upon others for 

 facts where it was possible to get information at first 

 hand. The substance of these lectures was afterwards 

 (1864) published as Lectures on the Elements of Comparative 

 Anatomy. 



The course of lectures on evolution to working-men.
