This Sufferers from the Clerkenwell Explosion.—Mr. Gant,surgeon at the Royal Free Hospital, Gray’s-inn-road, who has the care of the patients at that institution who were injured through the late explosion at the Olerkenwell House of Detention, reports that two of the sufferers, Harriet Roberts, thirty, and Emma Thompson, eight, have so far recovered that it is expected they may safely be disofikrged in a few days. Both of them were dangerously wounded. The boy Arthur Abbott, who is incurably blind, lies in a very pitiable condition, and, as described by the medical officer, “ in a state of living death/' Many of the out-patients injured by the explosion will soon cease to require surgical attention.
