sent to Casati with letters of credit were prevented from reaching him. It will be remembered that two of TippoTips men were sent in February of last year on this errand. They went from Zanzibar to Tabora crossed Karagwe Nike Air Max and reached Kasinga near the Muta Nsige in the middle Coach Outlet Store Online of May. They were however unable to enter Unyoro. as it was said that Mwanga had attacked the latter with an army of two hundred thousand men.

The messenger who Christian Louboutin Outlet carried the report to Zanzibar was not despatched by Stanley but learned the news from Arabian traders: therefore it is doubtful whether the report is true.

The British Government has refused the request of the Australian colonies to grant a subsidy to the proposed Antarctic expedition which was to be organized by a Nike Shoes Australia joint effort of the Australian colonies in case the British Government should support the undertaking. This decision will probably postpone the resuming of Antarctic exploration for an indefinite time. Although it is not probable that results of great commercial value will be obtained by an expedition of this kind Coach Outlet Store Online the scientific objects are Coach Outlet Store Online so great that this new delay must be greatly regretted.ELECTRICAL SCIENCE.Electricity directly from Heat.ATTEMPTSto generate electric currents by utilizing the fact that magnetic metals lose their magnetic properties when sufficiently heated have been made for some years. It is only recently however that such experiments have been made on a practical scale and with any promise of ultimate Christian Louboutin Outlet success. When we consider that in the most economical source of electricity the dynamoelectric machine we transform the energy of our fuel to the energy of steam under pressure then through Nike Australia the steamengine to mechanical work and finally by the dynamo to the energy of electrical currents losing energy in each transformation our ultimate return being perhaps ten per cent of the energy expended; when we add toIn his paper Mr. Edison gave no data as to the performance of the machine except the statement that a generator to feed thirty incandescent lamps would weigh two or three tons.Nothing has been heard lately of this generator: it will naturally take time to perfect it and make it practical.Within the last month however attention has been called to a machine using the same general principle as that of Mr. Edison but differing greatly in detail an invention of M. Menges of the Hague.One form consists of a Gramme ring within which is a stationary electromagnet. The two are horizontal and are separated by a considerable airspace: this space is rilled by a zigzag ribbon of iron extending around the inner circumference of the ring with which it revolves. Now if this ribbon of iron be cold most of the Nike Air Max 90 lines of force will pass through it from one pole to the other of the magnet: few will go
