IN the southern portion of Bering Sea, about thirty-seven nautical miles northwest from the island of Unalaska, lies a group of small volcanic islets known as Bogoslof, in Russian, Joanna Bogoslova, St. John, the Theologian. There are now three of these, all of which have risen from the sea, hot and steaming, within historic times.

FRED DE LAND
IN the fall of 1876, Gardiner Greene Hubbard began to systematically exploit the electric-speaking telephone invented by Alexander Graham Bell. In the vicinity of Boston a number of private telephone lines were strung, some of which were two or three miles in length, to connect mills and offices or offices and residences.

DR. MAURICE FISHBERG
THE assumption that Jews and Christians refrain from intermarriage because of an inherent racial antipathy existing between the Aryan and the Semite is disproved by the large number of mixed marriages in western Europe and America. All the facts go far to prove that the only reason why they have not intermarried during the middle ages and even as far as the first half of the nineteenth century was the difference of religious belief.

"IF only the devastating torrent of children could be arrested for a few years,” wrote one of the most sympathetic friends of progress, not so very long ago, voicing the opinion of the economists from Malthus to Fawcett, “it would bring untold relief.”

WILLIAM J. ROE
IT will be remembered what a spasm of apprehension seized the country when the prospect of war with Spain became imminent. Not only did these fears affect seriously the dwellers in sea-coast cities, but they were shared in to such an extent by those who had been accustomed to plan their summer outings at the sea-shore as to send a very large proportion to the mountains instead.

M. H. POINCARÉ
I HAVE shown in ‘Science and Hypothesis' the preponderant rôle played by the movements of our body in the genesis of the notion of space. For a being completely immovable there would be neither space nor geometry; in vain would exterior objects be displaced about him, the variations which these displacements would make in his impressions would not be attributed by this being to changes of position, but to simple changes of state; this being would have no means of distinguishing these two sorts of changes, and this distinction, fundamental for us, would have no meaning for him.

DR. CHARLES R. EASTMAN
IT is certain that Vesuvius, prior to the Plinian eruption of 79 A. D., by far the most tragic, and one of the three most violent in Italian history, was regarded as an entirely extinct volcano. The details of this eruption, the sequence of its phenomena, and its peculiarly destructive effects, are familiar to us from contemporary sources, and from the memorials written in large characters by the mountain itself over the ruined cities at its base.
