What an Arab ! %.ud what is more, what a splendid abdomen ! One of two things seems certain : either this doughty Arab has emulated the proverbial ostrich and partaken to over repletion of a diet of nails, or sad to contem plate, he must have partaken of absolutely nothing, and nothing with it, for weeks before, and so have presented merely a modest layer of skin between his adamantine backbone and the fusilier's faulty sword-bayonet, Anyhow, we should like to hear what ' Private Angus' and ' another fusilier' havo to say, supposing such individuals to exist." Ibe composing room of the New Orleans Picayune is situated m the upper story of its publication house, just under tbe roof, and m summer is extremely hot. An inspiration seemed to have come to one of the oppressed occupants and m accordance with it a vertical wooden box was constructed m the earner of the room, with openings ut tUs floor and ceiling, and furnished with a pipe for sup plying water at the top and a pan ad drain at the bottom for receiving the Cow and carrying it «afely away. The iupply pipo was bent over the upper end of the shaft and fitted with a rose like that of a watering-pot, so as to deliver a shower of spray instead of a solid stream. On connecting it with the service pipe the movement of the water was found to camn nn active circulation of the air m that part of the room, which was dra>*m m at the upper opening of the Miaft, and issued agiin, cool and fresh, at the floor level. The most surprising thing about the experi ment seems to have been the effect of the water m cooling the air to a degree much below its own tempersture. With M ioiiuippi water, which, when drawn indicated a tem perature of 84 degrees, the air of the room m which the thermometer at the beginning of tbe trial stood at 96 degrees was cooled m passing through the length of the shaft to 74 degrees or about 20 degrees below the temperature at which it entered, and 19 degrees below that of tbe water which was uted to cool it.
