last two months.

William, as you know, accompanied
his uncle and according to accounts
did good service as an assistant.
After an exposure to the cold of the
northern regions for several weeks,
we have thought it would not be
safe for him to return immediately

usual health.

With kind regards to your
family I remain as ever
Truly your friend
