 | Colonel Maendie concludes that one volume of liquid benzine will render l6, 900 volumes of air infiammable or 5000 violently explosive. Neither a glowing coal, sparks from flint and steel or A
 nameless fusee, however will ignite the most explosive mixture actual flame white heat being necessary.
 The Women's Anthropological Society of America the first purely scientific society directed exclusively by women, was organized in Washing ton m June, lss5. and has since held fortnghtly meetings from November to May. It now has three honorary, eleven corresponding, and forty six active members
 DEPENDED BARooNs.-A strange case of pro- tective alliance in animals is given by A South African traveller, Mir. C. II Lillie A Dutch trader, at distance from camp and unarmed was menaced by huge lion, when a troop of balloons suddenly surrounded him, and faced the hon with such horrible outcries that the mighty beast was glad to beat retreat. The balloons then scattered resuming their occupation of digging nuts and roots.
 TnE BESr DIsINFfcrANrs.-After giving long list of substances used, Prof. Diyardin- Beaumetz declares that the disinlectan above all is moist heat when 1t reaches 23o or 2t0 degrees Fahrenheit but as this temperature cannot always be applied,
 liquid and gaseous disinfectants are alo necessary Al the head of the first is placed corrosive subli- mate which is without an equal then, sulphate of copper Among the gaseous dsinfectants are pre- ferred sulphurous acid and chlorine.
 A NOVEL DEvIcE.-An "electric valve" by means of which the current can Ike sent in one direction but not in the other has been described by French electrician, NJ Neyrencuf With a voltameter constructed of two aluminium cleo
 rodes dilute acid eectrolyte and an alternating current, pure hydrogen was evolved at both cleo trodes but with one electrode of aluminium and one of mercury using distilled water as electroyte the current was found to pass in one direction only.
 The theory that tetanus is derived from the hOrse-as charbon, rabies and ganders are commu- nicated from the lower animals to man-was first advanced in 1885 by Prof Verneuil, who believes he has now fully substantiated this view The malady appears to be due to a bacillus-which may come from the animal direct, or may lie dormant in pastures, stables harnesses carriages giving rise to the locked jaw and other symp- toms on falling upon wound or other surface favorable for development.
 TALLY-STICK OF HIsToRY.-The covered reser- voirs of Carthage, now being restored by an engineering company of Tuns, are & remarkable record of the ebb and flow of civilization in one historically ancient spot These great works date back fully two thousand years, and have been in use several times at widely separated periods They were in full working order in the time of Hannibal, were again repaired under the emperor Hadrlan and until the present time have been entirely neglected since the occupation by the Arabs In 697 A. D. The reservoirs cover a space 20 by S94 teet and are divided into eighteen compartments.
 GREAT RAIN STORMS-In an investigation of lO6 cases of rainfall ranging from nine to twelve inches in eight hours, Prof. F. Looms has found the area of one inch rainfall to have extended at least 500 miles in length in ten cases and to have exceeded 700 miles in three cases while the entire rain area was frequently oval figure exceeding ,OOO miles in length by 500 miles in breadth Concerning these heavy rains the following facts seem we'll established: l. No great barometric depression with steep gradients occurs without consider able rain. This is true not only for the United States but also for the cyclones of the West Indies the China Sea, India and the Bay of Bengal. ?. In great rain storms the barometric pressure generally
