            Abstract : 
MR. TUCK: Mr. Taylor has given us a very interesting talk on a subject with which most engineers are not very conversant. I would like to ask if anything has been done to develop a way of measuring the diameter of holes in the neighbourhood of 1/2 in. to 1/10-in. ? He tells us of developments for indicating straightness, but the diameter and the roundness are a problem.
