| R.R. 235 B (50 T) (R.G. 504 8-1-20) G.{Mr Griffiths - Chief Accountant / Mr Gnapp} 7585. To Wd{Mr Wood/Mr Whitehead}/Ms. from EFC. X.3/41 EFC9/T27.4.20. X. 2065 - SYRINGE TYPE HYDROMETERS. Will you kindly obtain for our use in the Expl. Dept. two glass type syringe hydrometers from the Chloride Electrical Storage Co., similar to one you obtained for us recently as a sample in connection with hydrometers for the cars. We now require these as our celluloid one has broken down and these are the only ones we can obtain at present to enable us to take density readings. The reading of the instrument should cover the range 1100 to 1350. EFC. | ||
