A kind of mask to defend the face and eyes from accidents in various chemical and mechanical processes. A guard intended to preserve the face, and particularly the eyes of smiths, founders, and others, from being injured either by the heat of the furnace or of red hot melted metal, or of fragments of metals dispersed by the hammer, is described in the Transactions of the Society of Arts. The guard is of two forms, either a veil of iron wire-gauze of a curved form, and fastened by a hinge to the front part of the hat; or a musk, more or less complete, with the eye-holes covered with wire-gauze. There is not much novelty in the invention itself, but there is in its application to persons exposed to the radiant heat of furnaces, whose eyes, it is well known, often become much injured thereby. The great utility of it for these purposes, has been testified by a number of persons who have recently adopted their use, and have expressed their surprise at the trifling heat which they, in consequence, felt upon their faces.

The author of this invention, Mr. Callaghan, received a reward for it from the Society; and we have no doubt that its adoption by those classes of workmen for whose use it was designed, would prove highly beneficial to them.
