| X8783C. Extract from M/5 7.7.28 from Mr. Minchin X.4617S. With regard to the vent plugs, we took this up ourselves some time ago as soon as you reported it and put it right, but in the interval probably there were some cells in which the trouble occurred but that you will find to be quite all right now. | ||
