 Artificial Iron Ore.-A curious nh.. nomenon has just been brought to light hv the removal of lightning-rod. To the end Of the rod, which had been imbedded in fer. ruginous earth for about fifteen years. was found attached lump of iron ore, weighing ninety six pounds, supposed to have been aggre gated by the action of electricity from the surrounding earth.
 Camera Astrouomy.-A remarkable discovery, illustrating the value of photoera- phy In the study of solar physics, has been communicated to the Paris Academy of Sci ences by Mons. Janssen. On Tune aa, Ie85. there appeared on the sun's disc one of the largest spots ever detected there, which would hardly have been perceived, however If its occurrence had not been recorded by pho 'ograPhic apparatus.
 Origin of the Danube French geographer, Mons. DeWogan, has made the surprising intimation that the true source of the Danube is not yet generally known. He has found, by means of canoe voyage, that the great river is formed by the junction at DenauschinRen of two small streams, the Brig or Brigach, and the Breg or Bregach. The former rises about a mile from the source of the Neckar, whose waters flow into the Rhine.
 Black Snow.-A "black snow" which fell in 1873 over an area of about fifteen by twenty miles in the vicinity of Holland, Mich was found to contain considerable prOpor- tion of dark earthly matter.

 Non-Localiz ation in the Brain.-Says MT. Grant Allen: " To sum it all up: it is the brain as whole that thinks, and feels, and desires and imagines, jus, as it is the body as whole that walks, and digs, and dances. re locate, say the faculty of language in A particular convolution of particular hemis- phere is almost as absu' d, it seems to me, as to locate, say, the faculty of writing in the last joint of the right forehnger. Convolution and forehnger may be absolutely essential or indispensable for the proper performance of speech or writing but to say, that is, not to say that the function in question is there localized. The brain as a V hole is the organ
