Faraday to William Whewell   14 November 1844

Royal Institution | 14 Novr. 1844

My dear Sir

I am very much obliged for your kind letter¹. The word I want is mainly for the purpose of avoiding awkward & clumsy phraseology, for instance instead of saying "In this substance the Cagniard de la Tour point occurs at a pressure of &c"² I want a word with which to replace Cagniard de la Tour. It seems to me that a word expressing both conditions (vapor liquid) if there be such a one is that which is wanted for at that point the liquid is vapour & the vapour liquid, so that I am afraid to say the liquid vaporisces or that the fluid is disliquefied. It is too bad of me to give you this trouble & then not be content but the beauty of the experiment & its general results has always in my eyes been so great that I have constantly regretted we had not a word wherewith we might talk & write freely about it[.]

Again excuse me & if nothing occurs to you bringing with it at the moment its own conviction of fitness do not take any further trouble - not even to answer.

I am My dear Sir | YourVery Obliged Servant | M. Faraday

Rev. Dr Whewell | &c &c &c
