We learn, by the London Engineer, that Mr. J. Con-die, of Glasgow, tho inventor of the steam hammer illustrated on page 337, Vol. III. (old series), of the SCIENTIFIC AMERICAN, died suddenly on the 31st of October last. In company with a friend he had gone into a store to examine a painting, and, while standing at a distance viewing it, he fell backwards, gave two or three convulsive movements, and died without uttering a word. He was a very able engineer, and was respected by all who knew him. At the time of his da-cease, he was sixty-five years of age.
