 at Herrnhut, and on his way there he visited England, 

 France and Holland. At these places he visited learned 

 men, and established correspondences that were of great 

 advantage to him subsequently. Some time after his return 

 in 1821, he published a pamphlet containing descriptions 

 of seventy-eight hepatic^.* In the same year he sent to
