802 LIEUT.-COL. H. H. GODWIN-AUSTEN ON [JUUC 21, 



indebted to him for the fine collection he has succeeded in bringing 

 together in a few weeks. Having collected myself in the East, I know 

 he must have worked hard and well to do it, pressed as he was for 

 time, and that time primarily occupied with his own particular branch 

 of science, botany. When we consider also the birds, reptiles, and 

 insects &c. wliich he brought home, it is seen how very valuable the 

 results have been, considering the small outlay of money. Far 

 greater are they, and far more valuable, than those of many better 

 known and more costly expeditions, subscribed for and sent out by 

 scientific societies from this country.
