| X3741 Wd.{Mr Wood/Mr Whitehead} c.EFC. BY11-P22.11.22. X.3741. LUTHY HYDROMETERS. Referring to Wd{Mr Wood/Mr Whitehead}3/NJ71122, we think it desirable to carry on with the present type of Hydrometer, as quoted above, as it has certainly given us satisfaction, and we do not wish, at this stage, to be looking round for a new Hydrometer and having to adopt same without a reasonable trial.. If we can obtain samples of English made Hydrometers, which will reasonably compare for finish and convenience, with the Luthy, I think we ought to obtain samples and hand them on to EFC, in case the emergency which arose a little while ago, and now appears to have been dispelled, again arises.
