Through A Brick

"Yon wouldn't have believed it possible to blow out a candle flame through a brickbat," remarked a celebrated physicist, whose penchañt is to give scientific íesearch a practical bearing. "It can be done, however, and it illustrates the all-pervasive qualities of air. Most rooms are largely ventilated through their walls, and the brick and mortar are merely rudimentary lungs, which take in and throw out the atmosphere with little hindrance. "You may try the experiment yourself. Place a candle on the other side of your brick and use two funnels, with the flaring ends on the opposite sides of the brickbat with the small end of one in line with your mouth and the small end oL the other trained on the eanUe flame. The least breath wW mako the light flicker, and a hoarty expiration will extinguían it altogether, Try tt and see." . , .■■ .
