Under suitable treatment at the hands of hig valued friend and physician, Prof. James P. White, he improved considerably, and motion was partially restored in the paralyzed parts. The voice resumed its naturalness, and the patiënt seemed in a favorablo state of conyalesenco. On Thursday last - he experienced a return of the climculty, The next dy, Friday, by invitation of Dr. White, Dr. Gray of Utica, visited him, together with the first named gentleman. On Saturday and Sunday he became more lethargie, and an extensión of the paralysis took place toward the lower extremiites. Yesterday ho was unable to rise or walk about as after the first attack.
