Letter from Joseph Prentis, Jr., Suffolk, Va., to his son Joseph Prentis, at Colonel Woodley's Seminary near Smithfield, Va. He has taken his wife to Old Point Comfort, Va., to try to restore her health by the "salt bath"; the rest of the family is well except for Maria Louise who has the "whooping cough"; hopes he has recovered from his "indisposition"; mentions the tickets his son has won at school.
