BOTANICAL INFORMATION. 197 
come must now depend entirely on what the collections pro- 
duce, and do hope to be enabled to cover my expenses, for 
I always endeavour not to spend one farthing beyond what is 
necessary for the making of proper collections. 
“You were no doubt right in not sending me all the instru- 
ments I some time ago wrote to you for; the barometer 
would soon have been broken, travelling here is such rough 
work. My chief desideratum in this way is a good portable 
microscope, of the kind you generally use, for though I 
possess two excellent pocket lenses,'they are not sufficient for 
my purpose; and I will therefore thank you to purchase me 
such an one as your own, whenever you think my funds will

proceed to detail my proceedings since I last wrote. 
“On the llth of September, a few days after I had de-

* On reaching Jardin, I received the kindest welcome from 
the Capt. Antonio da Cruz, who, bearing of my intended 
arrival, had prepared a house in the town for my reception. 
country around was still more scorched than about 
Crato, and my collection consequently received but small — .
