| To H.{Arthur M. Hanbury - Head Complaints} From Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} c. to Hd.{Mr Hayward/Mr Huddy} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}3/MJ.23.12.30 With reference to the attached we think that the trouble is sufficiently covered in our Depot Sheat Hm.{Capt. W. Hallam - Head Repairs}127 where we say - "The rubber joint should be carefully examined before filling with Anti-freezing solution and if perished should be replaced, as Glycerine has a peni trating which is likely to open cracks in the perished rubber". We also state that we prefer Ethylene Glycol, one of the reasons being that it has not this searching action to such a pronounced degree.
