[Illustration] Mr. Stanton, a proprietor of collieries at Newcastle-on-Tyne, conceived the idea that if a bullet were made to receive the projectile force in the interior of the bullet, but beyond the centre of gravity, it would continue its flight without deviation.

The projectile B will, in a bent path, vary more and more from a horizontal straight line, and the light will do the same, because if we observe the movements from another standpoint this can have no effect upon the remaining next to each other of B and C. DEFLECTION OF LIGHT The bending of a ray of light thus described is much too light on the surface of the earth to be observed.

The remaining defect in the Morse machine, as first seen by me, was that the coil of wire around the poles of the electro-magnet consisted of but a few turns only, while, to give the greatest projectile power, the number of turns should be increased from tens to hundreds, as shown by Professor Henry in his paper published in the 'American Journal of Science,' 1831....

Its projectile weighs from 924 to 1,320 pounds, according to its internal organization.
