The followiug series of safety lamps, presented by Messrs. J. W. 

 Queeu & Co., Philadelphia, Pennsylvania, illustrate the principal forms 

 of such lamps:

 arranged as to obtain the best light possible. (59:<!6().)

 and is provided with a hook at the top to suspend the lamp from. (59267.)

 (59268.) 



(4) Fireman's lamp, embodying the principal of a Davy lamp, inclosed with iron- 

 wire gauze. It has a foot of small diameter and can be fixed by a hook to the wall 

 and hang perfectly straight so that the flame can be kept in the center. (59269.)

 the flame. Used particularly in Belgium. (59273.)
