Besides occasional discharges in thun- derstorJns, induction from neighboring charged wires, and currents due to chem- ical action of moist earth on b0ried conductors, telegraph and telephone wires are being constantly traversed by earth currents. These are sometimes 80 strong that the lines cannot be worked. M. Emile Gatrini, the French electrician, finds the cause to be still a mystery. although M. de la Rives has attributed the currents to chemical action in the earth's cruEst, while sun-spots. earth qttakes, and storms have been suggested as causes, and increased scintillation Of the stars has been noticed at times of strong disturbance. Perez del Pulgar, in Spain, has lately shown that they are affected by clouds. sunshine, fog and wind. An automatic recorder, called the electro tellurograph," has now been devised by Prof. Lancetta, an Italian. and will be used for collecting data to show the changes in earth currents with varying atmospheric conditions.
 The hydrobion of Dr. N. von Lorenz, of Marienbrun, Austria, greatly simpfiies the carriage of live fish. The apparatus water. and 1t consists of cylinder of compressed oxygen, with protecting grills, regulating valve, and porous cy-. Hinder through which the gas is slowly diffused into the water. The supply of oxygen Is easily adjusted, as the inven- tor has calculated the quantity needed by the fishes likely to be transported alive.
 In. recent European experiments, corpses havo been kept for a certain t.. ne 4t.t sA- 70 FAl.4 heated to 123 degrees, then taken out and steeped for twenty-four hours in a cold solution of sulphate of sodium. The bodies are transformed into perfect mummies. to be kept indefinitely.
 The association of colors with sounds, or ''color-hearing" is believed to be faculty of one healthy person in every ten. This and other mixing of sensa- tions occurs in certain abnormal condi- tions, and thet peculiar state of mind giving rise to it is now being studied un- der the name of .'synesthesia." In 6 re- markable case reported by Dr. Alfred Ulrich, of Zurich, the senses seem to have been all Involved at once. A boy of nervous temperament. who developed epilepsy in his thirteenth year. had al- ways heard colored sounds, different sounds of the voice and the cries of sn- imals having each it's characteristic col- or. The sounds of the vowels gave es- pecially vivid colors. A being light green E yellow, black, O red, dark green and Y white. Some sounds gave also sensations of taste, of temperature, and of form. Sensations of form were associated with color and sound, smells had colors. tastes had, colors. and colors had taste and temperature. Cold was green, and heat was red.
 False teeth, as firmly fixed in the gums
 as natural ones, are claimed by Dr. Zna- meusky a. Russian dentist, as a solution of difficult problem. The teeth--which may be of gutta percha, porcelain, or metal, have holes at their roots, and they are set in natural or artificial cavities in the jaw. The teeth are soon fixed firmly in place by a gradually hardening growth into the holes Several operations on hu-
 man beings as we'll as on dogs are re- ported to have been successful
 Acetylene is found to develop 1850 heat units per cubic foot. and coal gas only 63O the acetylene flame having tenn perature of about 2,600 degres F. An acc tylene burner consuming two cubic feet per hour raised a quart of water from 50 degrees to boiling point in 1-2 min utes, while illuminating gas, burning at the rate of 16 cubic feet per hour, re- quired 10 IA minutes.
 The Illuminating power of the sun at zenith is estimated by M. Charles Fabry at 100000 candles.
 A second blossoming of tres late in the season, after the usual forming of buds for the next year, may result from some injury, such as removal of the leaves, If the infernce of M. E. Apert is cor rect In October. 1900, this observer saw a white lilac in full bloom, the bush hay ing small. green leaves and beautiful clusters of flowers. while some hundreds of feet away was another bush of the usual autumnal appearance. Investigation showed that worms had eaten of the leaves of the first bush several months before A return of the worms in July, 1903. was followed by a partial repro duction of the phenomenon. and NJ. ApeTt believes that second Towering of fire injured tree reported by M. Jolly as a
