Scientific Points.

It has been found that sandstone as an engine foundation is far from perfect. The stone soon becomes saturated with oil, making it soft and easily friable. The first electric street railway in Bussia will be constructed at Kiew, a city of 130,000 people. It will be operaated by the trolley system, and will be ready for business this summer. A recent invention consists of a combination of levers in connection with the trucks of a railroad car, so that in case of derailment the airbrakes will work automatically and stop the train. The reservoir in a new lamp recently invented is spherical in form, and has a map of the world delineated upon it. The reservoir is pivoted at the base so that it- can be rotated on its axis like a globe for school purposes. According to the Journal de Medicine of Paris, the fumes of bromohydrate of ammonium have a beneficial effect in asthma and bronchitis. By an inhalation of the fumes under certain conditions an attack of asthma may be averted. The treasures of the Metropolitan Museum in New York are guarded by electricity. Underneath the lid of each case are wires, and if any one should try to lift or disturb the lids in any way a bell will give warning in the hall and in the office. One of the greatest novelties inweaving machinery recently invented is that designed by an Englishman, in which the pile in plush fabrics is gained in an expeditious manner during weaving. The picks or wefts are actually cut before being driven in. Thebe is great activity in the building of ships on the great lakes, fortyfive vessels being in course of construction at the present time, of which forty are steam. The new fleet will cost nearly $5,000,000, and will be ready for business early the coming season.
