CiGABKTtESMOKi.KG.— A Washington correspondent lua picked up a bit of interesting information regarding- cigarette smoking. It appears that a great many boys are applying to be apprenticed to iho navy, and according to "Major Histon, the commander of the marine barracks, at Washington, the first question asked when they come Up for examination is, whether they smoke. They usuaUy answer in the negative. The thumb and forefinger of the right hand ar« then examined, and in a majority of cases are stained yellow front 1 cigarettes. ..As. soon as this tell-tale mark is discovered the , boy is examined by a' surgeon for evid«aces;of heart diseaAo, and the* result is that ode-fifth' of aU.thelx>;s wh«- apply are rejected on accotins 6( cigarette smok-infc-i-Buffalo Courier. ' " , MjpiCATRD (?) FMNnJtL.T-Everyoni» has heard of red medicated flannel,- and white all might know that even if there could be such • , thing as medicated, flannel, washing would < surely remove all medication, and yet the saying ia repeated so often that people believe that there is something injlt. There h'. The truth is "this. The peculiar scarlet colour of What is called medicated flannel, can only be dyed on all wool fabric, hence, if a piece of flannel has that colour we can be sure that it is all wool, and therefore whenever an all-wool flanuelis the thing needed as a remedy or - preventive, to that extent, it is medicated. Electric Music. — M. Semmola, a German investigator, one. of the many ' who have experimented in this direction, hat succeeded in producing musical tones ,from a metal plate by electrifying it intermittently, from an induction machine. The plate is supported on an ebonite funnel, and is a millimetre in thickness. Ihe terminals of the induction machine are connected to opposite side* j of the plates by wires, and the path of I the current is interrupted so that sparks strike across. The plate then begins to sound, and it continues to sound even if a Geisler tube oru lead wire is interposed in tho break. Silver Soap.— The following are among the many preparations u*ed: Mix j pound jewellers' rouge with | pound prepared chalk.
