528 Mr. Faraday on the Condensation of the Gases, §c. 
not only had I communicated my results to Sir Humphry 
Davy, and received from him the hint, but my paper on fluid 
chlorine had been read (13th of March), and his note also, of 
the same date, attached to it; and the Editor of the Quarterly 
Journal, Mr. Brande, had time prior to the printing of my 
original paper to attach a note to it stating the condensation 
of chlorine and muriatic acid, and expressing an expectation 
that several other gases would be liquefied by the same means*. 
On the 10th of April my paper on the condensation of several 
gases into liquids was read, on the 17th of April Sir Humphry 
Davy’s on the application of condensed gases as mechanical 
agents, and on the Ist of May his Appendix to it on the 
changes of volume produced by heat. 
I have never remarked upon or denied Sir Humphry Davy’s 
right to his share of the condensation of chlorine or the other 
gases; on the contrary, | think that I long ago did him full 
“ justice” in the papers themselves. How could it be other- 
wise? he saw and revised the manuscripts; through his hands 
they went to the Royal Society, of which he was President at 
the time; and he saw and revised the printer’s proofs. Al- 
though he did not tell me of his expectations when he suggested 
the heating the crystals in a closed tube, yet I have no doubt 
that he had them+; and though, perhaps, I regretted losing 
my subject, I was too much indebted to him for much previous 
kindness to think of saying that that was mine which he said 
was his. But observe (for my sake) that Sir Humphry Davy 
nowhere states that he told me what he expected, or contra- 
dicts the passages in the first paper of mine which describe 
my course of thought, and in which I claim the development 
of the actual results. 
All this activity in the condensing of gases was simultaneous 
with the electro-magnetic affair already referred to, and I had 
learned to be cautious upon points. of right and priority. 
When therefore [ discovered in the course of the same year 
that neither I nor Sir Humphry Davy had the merit of first 
condensing the gases, and especially chlorine, I hastened to 
perform what I thought right, and had great pleasure in 
spontaneously doing justice and honour to those who deserved

+ I perceive in a letter to Professor Edmund Davy, published by Dr. 
Davy in the Life, vol. ii. p. 166, of the date of September 1, 1823, that Sir 
Humphry Davy said, “ The experiments on the condensation of the gases 
were made under my direction, and I had anticipated, theoretically, all the 
results.” It is evident that he considered the subject his own; but I am 
glad that here, as elsewhere, he never says that he had informed me of his 
expectations. In this Sir Humphry Davy’s negative, and Dr. Paris’s posi- 
tive, testimony perfectly agree.
