The common use hy a niimht-r of persons of Ihe same piece of snap, resting rest-ing often In a dirty dish, of towel and of hair bruMics ami conilis.

Hut there Is peihui a great need of reform In the home a In public plnres. Each member of the family should have soap, towel, hair brush, and every article of the toilet for his exclusive use as absolutely as be ha his tooth brush; and hia tnotltrush ahould rest upon Ita own dish, or, better still, i hang by Itself, and not share a dt.h with one or half a doxen othera. This necessity of Individuality In the I toilet shnuld be Impressed by, precept, and by example upon every child from' the very beginning, for tho practice o: perfect cleanlluiis may not only prevent pre-vent aome dlaagreenhle skin eruption, but also more serious dUease. riHII-HCAI.INI) IMI'I FMKNT.
