For thi purpose thc nautical ball iS furnished with grapn"is and hooks on tho ou:s siic w,,ich can be ma nipulated from the interior. Both on tbo surface and under the sea it can be steered either in a direct line or turned with perfect ease.
 Among tho e who witnessed the ex- periments with this vessel at Civita Vecchia the other day were competent persons sent by the Ministers of Marine. of War, ot Industry and Commerce and of Public Works, who are to report on this new invention. The ball under went all the experiments perfectly and without a hitch. It was made to sink several meters below the surface of the sea, and directed straight to a large ship, under whose hull it passed large, fiat board was then thrown into the sea, the nautical ball being invisi. ble, as it was still under water. By and by loud report was heard. A mass of water rose close to where the board had been, and as the foam produced by the explosion cleared away all that was to be seen of the board was a few shattered remains. Those in the ball had seen the board thrown into the sea, had at once proceeded to it. placed their cartridge under it and had cleared out of the way before the explosion took place. To il- lustrate how quickly the getting owt of the way can be effected. the ball was brought to the surface the moment the explosion was over good forty yards off.
 "A beam with weights attached to it, so as to make it sink, was then thrown overheard off the st"amer on which the spectators were watching. The ball sank after it and in few m 'nuGes to the surface again with the bean, which it had picked up with it's grapnels. The cxactitude and precision of tue d;fficult maneuvers were greatly praised. The machinery in this experimental Lall is worked by hand-both propeller. steer ing and other apparatus. In Q much la ger ball, which the en- gineer intends constructing, tho propeller will be driven by an e!ectr;c motor. Another most mportan atter that this submarine ball has solS S"d ;n the taking of submarine photographs. Tho principle on which this invention of Sig. Balsamello is based is the law of tho spec tic weight Of bndies; but the "phere form adopted for this nautical bail is q new theory, which. perhaps, might be q fficuit to understand. In fact. telling the t:.ing as it is, it would seem impossible that the round body could have a rcctilinear motion. But profound study has demonst tra tel that such can be the Case. Not only does this ball navigate in a strn gns line, but when it is necessary to tnrn it it does so with the greatest eas- on its own axis, which in naviga tion is a g-~at advantage. Inc government has looked with much favor on this invention of Sig. Balsamello and it is thought prob- able that it will buy the patent"
