IMPERVIOUS GLOVES AND MITTENS. 315 



MECHANICS' APRONS 



Are made of perforated, felt or vegetable leather ; when made 

 of the water-proof fabrics they have been found too warm. 



CHILDRENS' APRONS. 



Corded tissue and vellum, plated muslin, and perforated 

 vellum, are in general best suited for infants' bibs and childrens' 

 aprons. 



DISSECTING APRONS 



Are made of corded perforated vellum, or plated fabrics, with 

 sleeves and gloves attached. See Chapter VII., Medical and 

 Surgical. 



IMPERVIOUS GLOVES AND MITTENS 



Are made most commonly of knit goods and napped elastic 

 compound. When made of elastic compound they are con- 

 structed in a peculiar manner, with non-elastic stays upon the 

 seams, in order that they may be conveniently drawn upon the 

 hand. They are designed to be worn over other gloves and 

 mittens, and to be used in various departments of labor and 

 occupations, where those engaged in them are obliged to have 

 their hands in liquids that are injurious. Hatters, chemists, 

 dyers, and numerous other tradesmen, who have to make use 

 of strong acids and alkalies, will find them useful. For house- 

 wives and servants, who handle coal and ice, and for washing, 

 especially when the hands are dipped alternately in hot and cold 

 water, or when they are chapped, they will be found very 

 valuable.
