It was proved by Nenning, and the pathogenesis contains some striking symptoms, many of which have been confirmed. Sir James Y. Simpson used the Sulphate of Nickel (NiSO4) in "periodic headaches of a very severe character," and the provings show that the metal and the carbonate are equally appropriate in this connection. H. …
