099 66 p.p.in for 10 dnys dcstroycd the power of geriniiintion. He doubted very much whcthcr tlic conccntrntions of SO, conccrncd in tlic present case or occurring in cities would hnvc nn insccticidnl effect. The average hunian bcing WRS supposcd to be able to srnell concentrations of SO, down to 3 parts per million, but he confcssetl tlint lie liinisclf could not recognize the gns st tlint dilation.
Dealing with RIr. AIcLuchlan's question as to the rntc at which sulpliur dioxide ivns diluted and diffused, he said it wiis generally recognizcd that, tho greater the height n t which SO, wns discharged nnd the higher tlie tcinpcrnture at which i t ivns disclinrgcd, tlic more likely was it to bccome dilutcd to the point of being iunocuoiis before it rcnclicd ground levcl. Some very interesting conclusions could undoubtedly be drawn froni n study of the tlntn of the present invcstigntion as to the rate tit wliicli SO, ciiiittcd from n single source bccninc dilutctl a s distuncc increased.
At tho conclrision of tlic discmion, n hearty vote of thanks mns accorded Dr. Wliitby for liis lccturc.
