 Traces of prehistoric race have been
 discovered in Jamaica by Mir. K. G. HaI.
 burton. From the skulls obtained he iudo.,
 that they were people of great natural intelG

 their habits were peaceful and industrious.
 The importance of fostering scieutis.
 research is recognized by the republic ot
 Mexico, which has established a Sc;en,;so
 Commis sion. con posed of the most learned

 investigations in every department of huma,

 Successful experiments have been mad. in joining and res toring he functions of d. vided nerves, even nerves of differen, hpc- ton being used to replace those partially de. | stroyed. It is bought that even siph, and nearing may be restored, after iEjury to ihe nerves on which they depend, by brinpin, other nerves into service by artificial unio,
 The Pyrophore. Several specimens of the Mexican pyrophore were lately exhibit,d 10 the Paris Academy of Sciences as ,e~s markab'e novelty. These insects are sbou, an inch long, and emit light like that fl q glow-worm or fire fly. but vastly more bril-. liant. he Indians of Me xico are said to keep them for light at night, and NJ, xicau ladies wear the m as ornaments in the hair. Byf fee ding them on sugar. cs ne they may be kept alive long time.
 The Influence of Weeds-From com. parative experiments, Prof. E. Wolny the German investigator has shown the effect of weeds upon the productive power of plants Both quantity and quality of the crops were seriously affected by alle wing the weeds to grow, the injury be ing the greater the more slowly the plants were devele ped Peas and summer rape suffered least beans, maizeand potatoes were injured to the extent of 4s to 6o per cent; and beets showed loss of % per cent.
 Earthquake Resisting Foundations The earthquake committee of the British As. sociation has described experiments made in Iapan-the home of earthquakes-in placing a house upon rollers resting upon the founaa- tion With ten-,rch iron balls the earthq lake shock was made less sudden, but the build. ing was easily moved by the wind. Smaller balls were tried, until finally the structure rested on a handful'of quarter inch iron sho, placed upon each of the supporting pillars. By this arrangement the effect of earthquakes is greatly mi,igated with, ut exposing the house to danger from the wind.
 Natures Oxidizer.- Ozone, supposed to be yer active form Of oxygen, has been thought to exert so beneficial an influence that an increase in the atmospheIe's propor- tion-which rarely averages more than one part in 7oo,ooo-ha, been hailed as token of a particularly healthful climatic state. Flow ering plants especially the edorous kinds and scented foliage have been pronounced of hysienic value because they generate osose. ratb CT surprising announcement, therefore, is that of pr. Daniel Draper's sup posed discovery that czone produces pneu monia, but it seems quite proeab tha, the gas which so powerfully destroys organic i'm purities may be proven by further research to act as an irritant of the lungs.
 A Climate Changing Project-A polar current appears to defect the Gulf Stream from the shores of the U United States and the British provinces, and iaterpose cold wall of water between the land and the genial warmth Of the current fir om the tropics. These refrigerating waters pass between Labrador and Newfoundland and by building dam across the narrow Straits of Belle lsle-about ten miles wide and averaging Iso feet iu depth-Mr. John C. Goodridge, jr., suggests that the polar stream might be turned asde into mid-ocean. Then, it is believed the Gulf Stream would skirt the American coast and materially change it's climate from Cape Hatteras to Newfoundland, freeing the Gulf of St. Lawrence from icebergs and giving to Nova Scotia the mildness of Cape May.
 A Scientific Huxley has asked whether, if it were certain that the life and fortune of every one of us would one day de- pend on our winning a game of chess, we should not all learn something of the game. |" Yet it is very plain truth that the life and fortune of every one of us depend on our knowing something of the rules Of game infinitely more difficult. It is game which has been played for untold ages, every mau and woman of us being one of the two players The chess board is the world the pieces are
