Show scientific miscellany Z central depots where milk to Is received and filtered before being taken to the consumer are now a a feature of several european Europ eian cities large cylindrical vessels are divided horizontally near gieir center by compartments con taming sand of three successive degrees of fineness the coarsest being the lowest and as aa the milk arriving from the country to Is PO poured ared through a pipe into the bottom of these vessels it rises through the sand filter and is run oft off by an overflow w pipe into a cool cistern from which it is drawn directly into locked cans for distribution the send sand Is renewed each time the filter Is used the dirt is in separated from the milk the number of bacteria are reduced to one third and an astonishing quantity of mucus cilcus and slimy matter Is removed the loss loes of fat being very sight A peculiar method of brick balc burning has hae been noted tri in corea by M henri chevalier a french engineer the bricks are first thoroughly burnt then without cooling are flooded with water and the fires being kept up several days longer are finished in an atmosphere of superheated super heated steam the bricks are blue in color and very hard they have a crushing strength of tons per square foot and axe are practically unaffected by frost but how much of their fine quality depends upon the singular burning process is not clear the food needs of racing cyclists has been a subject of study by dr lucas of parts paris who approves the course of competitors in the paris carls bordeaux contest who abstained from food containing nitrogen while drinking enormous quantities of liquid tea beef tea and milk to replace the loss by perspiration it Is useless to eat in violent exercise he declares but important

causing one to wonder that even slight alight scratches not to mention the deep incisions of surgery do not inevitably cause bleeding to death the tendency of blood to coagulate is a detail in natures
