Comparative data on the volume of foam and the stability of foams of aeronautical lubricating oils produced at 100 deg C by the air bubbling method are presented. The procedure consisted of noting the rise in level of the foam at definite time intervals up to 8 minutes after bubbling commenced. Preliminary experiments showed that the foam height remained within ten percent of its steady value 8 minutes after air input was stopped. Volume increase and percentage volume increase were calculated.
