SUDDEN CURE. - Mr. Henry J. Parsons of Glenburn, who was a soldier in the 1st Maine Artillery, was deprived of his speech about 18 months ago. After trying several physicians he was induced to apply to Dr. Quinby of this city, who, by some mysterious process restored his speech in a few moments, so that he talks as distinctly, although not as strong as before. His uncle, Mr. Dyer, feeling very grateful to the Doctor, wishes us to say this much in regard to the case.
