 in order to take his degree before sailing with Ross, and how, 

 there being no other time available, he slept with them under 

 his pillow, and read them before getting up in the morning.

In the letters from the Antarctic there are several references 

 to Darwin, who saw various of these letters through the Lyells.

Only the first two or three letters open with the formal
