PliMphorericem Bacteria. At a meeting of the Academy of Sciences at Fienna, Professor Molisch, of Prague, communi- cated a paper upon phosphoresceut bacteria. He has been able to photograph the colonies of a phosphorescent micrococcus by means of its owt Ught. By inoculating large glass flasks of 1-2 (tres capacity containing a suitable culture medium with the organisms, a "bacterial lamp" is obtained with which it is quite possible for an observer at a distance on one to two metres to read a thermometer Or to see the time of a watch. On a dark night the "bacterial lamp" is visible at a distance of more than sixty paces. It is suggested that such culture* of phosphore ieent bacteria might be employed in Sowder magazines, or for attracting fish, as ths ask might be sealed up and lowered into the water. Onder suitable conditions the phosphorescent properties cf the cultures last for two or thMe weeks.
