Charles Darwin. 



Darwin says : " I thank God I shall never again visit 

 a slave-country. To this day, if I hear a scream, it 

 recalls with painful vividness my feelings, when, 

 passing a house near Pernambuco, I heard the most 

 pitiable moans, and could not but suspect some poor 

 slave was being tortured." The Cape Verd Isl- 

 ands were next visited, from there sailing to the 

 Azores, and on the 2d of October the Beagle cast 

 anchor at Falmouth after an absence of nearly five 

 years.
