The following letter was read : — 
Sir, 
1. I have to call attention to some errors in Mr. Dyer’s 
representation of the nature and contents of a short Essay of 
mine, which was read to the British Association, in 1854, 
and reprinted, with a few abridgments and emendations, in 
the “Engineer” for the 23rd of January, 1863, and which 
Mr. Dyer criticises in his “ Notes on the Action of Heat 
and Force upon Matter,” read to the Literary and Philoso- 
phical Society of Manchester on the 1 1th of March. 
2. Those errors consist, in the first place, of a complete 
misconception of the object of my Essay ; and in the second 
place, of misquotations, in which, by the alteration of some 
words and the omission of cithers, the meaning of my state- 
ments is perverted or reversed. 
3. I have no doubt that those errors arose merely from 
inadvertency on the part of Mr. Dyer ; and I trust that, when 
they are pointed out, his own sense of justice will make him 
see the propriety of having them corrected before his Paper 
is published at length in the “ Transactions.” 
4. With regard to the object of my Essay, Mr. Dyer says 
(at page 78 of the abstract of his Paper), “ Yet we have 
seen two elaborate essays, by Dr. W. J. M. Rankine and 
Mr. Tyndall, each based on the force-heat assumption, but 
■without affording any solid proofs of its application to the 
phenomena adduced by them.”
