portance in sanitation; t h a t organic poisons do not exist; t h a t odors are a nuisance. It has been shown that ozone removes these odors, and while i t has been demonstrated t h a t in strong concentrations ozone destroys these odors, many writers, including Jordan and Carlson, persist in the unsupported allegation, t h a t in weak concentrations, ozone although admittedly banishing them, merely masks these odors. Wide experience attests that ozone improves the condition of the air, and inasmuch as all attempts have failed t o prove the least harmfulness of ozone when properly used, its utilization is as fully justified as is the use of such empirical remedies as, for instance, colchicum in gout. hIILTON W.

PLATINUM THIEF
Editor of tlLe Jourrtal of Industrial and Engineering We desire to call the attention of the Society to the recent theft of platinum from this laboratory. The party suspected is a man calling himself Harry E . Newton and representing himself as a graduate of the Rolla School of Mines at the University of Missouri, ’99. He claims to have been connected with
83
smelter work in Southern hlexico and also with the rubber industry in t h a t country. H e is a man approximately 35 years of age, 5 feet 5 inches in height and weighing about 135 pounds. His complexion is dark and when last seen he was smooth shaven, with a face showing marks of considerable exposure to the weather. He has the appearance of a man addicted t o the use of drugs in some form. We have communicated with the secretaries of the four nearby sections and would be glad to receive any information as to his present whereabouts. \VILLIAMETTE PULPAND PAPERCOMPAXY OREGOS CITY,OREGON DECEMBER 1, 1913
RECOVERY O F IODINE FROM T H E WASTE LIQUOR I N COPPER TITRATIONS Editor of the Journal of Industrial and Engineering Chemistry: The waste liquors obtained from copper titrations by the iodide method contain large amounts of iodine This may be recovered by adding hydrogen peroxide (a few cc. of 30 per cent to about 2 , j liters). The free iodine is precipitated at Once and can be easily separated by filtration, GREGORY TOROSSIAN 11014 DETROIT AVE , CLEVELAND. N O V E h l B E R 20. 1913
