��A New Safety Razor with a Lamp Attachment
AX Rni;lisliiiian, \vear\- of bloodslied, lias l)clli<)Ught him of a means of cnliglilcning the gloomy and otherwise dangerous ritual of the shave. He has invented a miniature electric lamp pro- vided with an ad- justable clip and flexible cord which may be attached to the r.Lzor and light the path of the blade through the tough bristles of the human face.
With his lamp attachment one may plunge fear- lessly into the blackest depths of a three days' growth of beard and emerge from the ordeal un- scathed. The lamiJ is attached to a conventional type of razor by a simple clip. It travels with the blade or with the motion of the hand. By look- ing into the mirror the man shaving himself can deter- mine just what l^rogress he is mak- ing and whether or not he is going to come through the operation with his two ears intact.
The lamp clip can be attached to any one of the many makes of safety razors. The inventor is now busy on another lamp attachment for the old type of razor.

��What Makes the Hair Suddenly Turn Gray?
APHRNOMENON that has always cU'oused curiosity is the sudden turning gray of the hair under the in- fluence of great emotion. Several his- torical instances are open to doubt, such as the case of Marie Antoinette, who is said to ha\'e be- come gray in the night before her execution, but there are several well authenticated cases vouched for by medical obser- \'ers. One of these refers to a young soldier in the pres- ent war.
He was in a trench in the Ar- gonne district which was blown up by a mine. He was projected into the air and then fell beneath a pile of debris. When he was extricated he was found to be deaf, and a few days later in an English hospital he noticed to his great surprise that there were tufts of white hair on t lie left side of his head. The loss of color was complete from the roots to the enilsof tiie hairsand the longest hairs were just as white as the shortest. There was not a brown hair amidst them. The gray hairs were solidly implanted and could be pulled out only by considerable force. Subsequent investigation brought out the fact that the patient's left side of the head and face was most injured by the explosion and the fall of earth. He also sulfered from an incessant twitching of the left eyelid. As his hair was whitened solely on the left side the physicians came to the conclusion that the injuries sustained were directly responsible, but they arrived at no definite conclusion. In fact, science has yet to find a. cause for the sudden turning gray of the hair.
