BY TYE ENGLISH CORRESPONDENT OP THE SCIENTIPIC AMERICAN. cently in sinking a well for power-station circulating water he utilized the shells of two water-tube boilers sinking them One above the other to a depth of 36 feet. The Budde Hydrogen Peroxide Process for Sterilising Rink. PLAYING A 'CELLO BY COMPRESSED AIR. inexpensive as to enable the purified milk to be sold at the customary - price. The milk upon collection from the various farms is brought to a central depot where it is raised to a temperature of 122 deg. In this heated condition it passes through a centrifugal cleaning machine similar in design to a separator but having only one outlet the cream not being separated from the milk. This operation not only removes all particles of dirt suspended in the milk more effectively than ordinary filtering but also serves to arrest any bacteria that may be adhering to the foreign articles and to the minute motes of the tissues of the cow which are always present in milk. It may be men tains to be necessary in any milk treatment since ex periments have proved that the bacilli adhering to these different particles are the most resistant. Strik ing illustration of the extent to which dirt is present In milk is afforded by the amount of residue that is raw milk has passed through. From he cleanser the milk passes into a water jacketed glazed earthenware vat in which it receives with a mechanical stirrer which is actuated from time to time to create and maintain a homogeneous mixture. The peroxide is perfectly harmless when taken in small quantities. The amount used by Dr. Budde Is very minute. The chemical Is added to the fluid when heat ed to the temperature of 122 deg. F. The effect produced upon the milk by the hydrogen peroxide is that the enzyme catalase first isolated by Loewe at Wash ately decomposes it into water and oxygen. The result is that the one volume of oxygen thus released—hydrogen peroxide consists of two equal parts of of oxygen. Consequently for
