My dear Hubbard:--
I return herewith the result of the Physical Tests of the Heads for Torpedo Air Flasks.
I think we have every reason to congratulate ourselves that the material which enters into the manufacture of the Whitehead torpedo is equal, if not superior, to that use abroad.
Very truly yours,
Inspector og Ordanance, Torpedo Station.
