Abstract
I HAD expected to see some confirmation of the remarks that form the chief part of the letter on this subject by Dr. H. J. Johnston-Lavis in NATURE of the 30th ult. (p. 197), but as no one has taken up the matter yet, perhaps you will allow me, as for years the chief assistant of the late Robert Mallet, to say that it is quite true that elaborate apparatus was devised by him and made by different instrument-makers, with a view to obtaining experimental imformation on the whole of the questions and more than those referred to by Dr. H. J. Johnston-Lavis. A preliminary report was presented by him to the British Association in 1863, in which the scope of his inquiry and nature of apparatus were mentioned, and other reports were written by him which I have not by me now. I am also able to say that the whole of the apparatus remained for years, through Prof. Guiscardi, in the University of Naples, and that Mallet wrote to him as to its disposition for the use of others, should occasion permit, just before his death.
