“Your printers have made but one blunder,Correct it instanter, and then for the thunder!We'll see in a jiffy if this Mr S[pencer]Has the ghost of a claim to be thought a good fencer.To my vision his merits have still seemed to dwindle,Since I have found him allied with the great Dr T[yndall]While I have, for my part, grown cockier and cockier,Since I found an ally in yourself, Mr L[ockyer]And am always, in consequence, thoroughly willin',To perform in the pages of Nature's M[acmillan].”

“It is very desirable to have a word to express the Availability for work of the heat in a given magazine; a term for that possession, the waste of which is called Dissipation. Unfortunately the excellent word Entropy, which Clausius has introduced in this connexion, is applied by him to the negative of the idea we most naturally wish to express. It would only confuse the student if we were to endeavour to invent another term for our purpose. But the necessity for some such term will be obvious from the beautiful examples which follow. And we take the liberty of using the term Entropy in this altered sense ... The entropy of the universe tends continually to zero.”
