 SCIENTIFIC MISCELLANY.

but always owes It's origin to microbes from rAhid animal
 An attempt is being made at StPetsrsburg to test the accuracy of barometrical measurements. Some instruments were taken up more than mile in balloon, several barometrical determinations of the height being made by the aeronauts simultane- ously with angular measurements by surveyors st I've different stations.
 ORGANISMS IN CHEEsE-No fewer than nineteen species of microbes in kind of cheese-and that In fresh state-have been found by Prof. Adamefz. of the School Of Cheese Manufac ture at Sornfhsl in Switzerland. Every eramme Of the cheese con- tained from 9O0O0 to 10000 bacteria, which in- creased to more that S00,00 in 70 days. Tn soft cheese S4 days old the number WAS calculated to be 100000 to the gramme, and 2O00,0OO in q specf. men 45 days old This was the interior while on the rim there were from 900 900 to 900 900 for every gramme. It was proven that the arrest of these organisms prevents the maturing of the cheese A MrLE-TRIr BY ELEVATOR one has sug- gesed that, instead of initiating the idea of build ing tower higher than any other for the worlds fair of 1892, the original idea be adopted of exca- vstng deeper hole in the earth than has yet been made. The small village of Schladeback in Gar. many, now claims the deepest hole yet bored, meas uring about 5735 feet iu depth, and conple' cd

 ZINC ON BUILDINGS builders of the City Market halls in Berlin found that some sheet zinc work resting upon brick walls soon became deeply ptted in number of places especially at points of contact with the bricks. Chemical examination has shown that the bricks contained more than one per cent of soluble salts, capable, aided by moist ure, of producing the destructive effects noticed It is probable that some bricks are free from the corrosive salts but wise precaution would Dc to avoid immediate contact of sheet zinc and brick work by nterposing some material-like building felt-not likely to be attacked.
 PARASITES or THE BLooD-Some years sgo a Russian observer discovered in the blood of birds living organisms strongly resembling those exist ing in the blood of persons attacked by malarial fever. 1t has since been found that these minute parasites are much more common than was ct first suspected Cold -blooded animals are especially
 liable to them and the carnivora more so than other warm blooded animals but 1t is only rarely that they seem to cause inconvenience, and in only four or i've out Of three hundred birds examined did death result in conse quence of lesons produced by the parasites. In those cases the symptoms were
 identical with those observed in victims of malaria fever.
 INSECT SPEED The rspidity with which insects travel is quite astonishing, often exceeding the speed ot the swiftest race-horse. The common house-fy is computed to make six hundred strokes per second in ordinary flight, advancing twenty
 i've feet, but this rate may bs increased to six or seven times as much. Leuwenholk tells of dra- gon- fly which, in 6 menagerie about one hundred feet long, succeeding in avoiding a swallow and in recent curious race, at 6 Westphalian town, be- tween 6 dozsn bees and a dozen pigeons, the first bee finished the distance of three miles nearly quarter of minute in advance of the first pigeon The male of the silkworm moth is said to travel more than one hundred miles in & single day.
 TIE ELIxIR The discovery announced by Prof Brown Seqnard last June was not the "e.ixir of life," but simply that certain glanduar secretons act as stimulsnt of the nervous centers and would probably be found a remedy of value. According to Dr. G. Archie Stockwel the researches into this chemist MT. H. F. Mier, with the result of isolat- ing an alkalod which proves to be the active agent The alkaloid Is identified spermine announced by S,hreiner in 1878. The phosphate of spermine exists in all normal gray nerve matter of the brain
