| X.3741. To BY {R.W. Bailey - Chief Engineer} /C. from EFC. {E. Fowler Clarke - Electrical Engineer} EFC {E. Fowler Clarke - Electrical Engineer} 2/T15.5.25. EXIDE HYDROMETER TYPE S1. X.3741. We have now made tests on this hydrometer and attached please find my assistant's report JB.103., from which you will see that apart from the obvious delicacy of the glass float, and one minor point made clear in the report, this hydrometer is considered to be generally satisfactory. We return the instrument herewith. EFC. {E. Fowler Clarke - Electrical Engineer} | ||
