. THE VOYAGE. 53 



likely to see ; and this habit of mind was continued during 

 the five years of the voyage. I feel sure that it was this train- 

 ing which has enabled me to do whatever I have done in 

 science. 



Looking backwards, I can now perceive how my love for 

 science gradually preponderated over every other taste. Dur- 

 ing the first two years my old passion for shooting survived 

 in nearly full force, and I shot myself all the birds and ani-

 but were driven back each time by heavy gales. These two 

 months at Plymouth were the most miserable which I ever 

 spent, though I exerted myself in various ways. I was out 

 of spirits at the thought of leaving all my family and friends 

 for so long a time, and the weather seemed to me inexpressi- 

 bly gloomy. 1 was also troubled with palpitation and pain 

 about the heart, and like many a young ignorant man, espe-
