Mr. Faraday on the Condensation of the Gases, Sc. 527 
pected that the chlorine had been entirely separated from 
the water by the heat, and condensed into a dry fluid by the 
mere pressure of its own abundant vapour*.” I then de- 
scribe an experiment entirely of my own, in which I proceed 
to verify this conjecture, and go on to say, “ presuming that 
I had now a right to consider the yellow fluid as pure chlo- 
rine in the liquid state, I proceeded to examine its properties, 
&c. &c.+” 
To this paper Sir Humphry Davy added a notet, in which 
he says, “In desiring Mr. Faraday to expose the hydrate of 
chlorine to heat in a closed glass tube§, it occurred to me that 
one of three things would happen; that it would become fluid 
as a hydrate; or that a decomposition of water would occur, 
and euchlorine and muriatic acid be formed; or that the chlo- 
rine would separate in a condensed state.” And thenhe makes 
the subject his own by condensing muriatic acid, and states 
that he had “‘requested” me, (of course as Chemical Assistant, ) 
“to pursue these experiments, and to extend them to all the 
gases which are of considerable density, or to any extent so- 
luble in water;” &c. This I did, and when he favoured me 
by requesting that I would write a paper on the results, I began 
it by stating “that Sir Humphry Davy did me the honour 
to request 1 would continue the experiments, which I have 
done under his general direction, and the following are some 
of the results already obtained:||” and this paper being im- 
mediately followed by one on the application of these liquids 
as mechanical agents, by Sir Humphry Davy 4, he says in it, 
‘* One of the principal objects that I had in view in causing ex- 
periments to be made on the condensation of different gaseous 
bodies, by generating them under pressure, &c.” 
1 certainly took up the subject of chlorine with the view of 
pursuing it as I could find spare time, and at the moments 
which remained to me after attending to the directions of my 
superiors. It however passed in the manner described into 
the hands of Sir Humphry Davy, and a comparison of the 
dates will readily show that I at least had no time of my own 
to pursue it. My original paper was published on the first 
of April 1823, that being the first number of the Quarterly 
Journal which could appear after the experiments had been 
made: but in the short time between the first experiment and 
the publication much that I have referred to had occurred, for
