customary annual visit. The rains have as yet had no sensible
effect on vegetation except to cause Mammillaria radiosa to
flower copiously. We have here (I suspect) M. vivipara on the 
mountains but the fruit is red not green as stated in the Flora.

I hope you will neglect no opportunity of sending to me any 
thing you may be able to procure which will be really useful
to me during my sojourn so far from anything literary or scientific.

of my feelings to say that I would be grateful to receive long &
frequent communications from you.

Most sincerely,
Your obdt [obedient] Servt [servant]
