NOTES ON MIMOSEÆ. 571 
After I leave Moxos, I shall ascend the River Piray, and 
land within a few leagues of Santa Cruz de la Sierra, and 
thence return again to Cochabamba. Should I only have 
health during this journey, I shall, without doubt, form an 
extensive collection of Natural History, which may tend to 
make known the Bolivian Flora in England; better, at least, 
than it is understood at the present day. It is not possible 
for you to form any conception of the expense and difficulty 
of conveying things after being collected, in this country, 
without roads and the means of transportation. Soon after 
my arrival in Trinidad, I will do myself the pleasure of 
writing to you again, and am, 
Sir William, 
“ Your obedient and obliged servant, 
“Tuomas BRIDGES.”
