| -3- With regard to the oil test previously referred to, we have for a number of years used some form of oil flow test. It has been of invaluable service, particularly on aero engines as an indication of the condition of bearings, without the necessity for dismantling or re-assembling. We should profit by this experience and make more use of oil flow tests on car work. With the use of an apparatus which has already been developed by K.{Mr Kilner} the condition of the bearings in an engine can be established by a test which takes less than one hour. It has been found particularly valuable for ascertaining the condition of bearings on a car sent in for a certificate for re-sale purposes.
