Mr Tonimasi’s complaint that his work on nascent hydrogen had been overlooked by Mr Franchot is based on a misapprehension of the facts. I t was in consequence of the very interesting results obtained by Tommasi that Franchot started on his work. I t happened that so much time was wasted in discovering and eliminating the errors introduced by the direct action of the metal that the point was not reached at which one would naturally make a reference to Tommasi. T h e unfinished part of the paper included a study of Tommasi’s hypothesis that nascent hydrogen is H x calories. If this represents the facts, there must be different amounts of reduction when zinc or copper is attacked by acids. This has not been shown conclusively to be the case nor has there been any careful study of the subject from the point of view of modern electrochemistry. There is therefore much interesting work to be done, starting from Tommasi’s results. T h e papers of Tommasi, published in Italian, were known to me by title only since I have not yet been able to obtain copies of the originals.
