PROVISIONAL SPECIFICATION.
A Receiver for the Preservation and Application of Chloride of
Ethyle.
I, BENJAMAN JOSEPH BARNARD MILLS, of 23 Southampton Buildings in the
County of Middlesex, Patent Agent, do hereby declare the nature of this invention,
a communication to me from abroad by Messrs. Auguste Gilliard, Prosper
Monnet & Jean Marie Cartier of 8 Quai de Retz, Lyons, in the Republic of
France, Manufacturing Chemists, to be as follows:-
The chloride of ethyle can be employed as an anesthetic, but its great volatility
renders its preservation and employment difficult.
The communicators, being manufacturers of chloride of ethyle, have devised a
practical means of preserving it without alteration and of employing it readily without
having recourse to any apparatus other than the receiver which contains it, which
thus also becomes a surgical instrument.
To this end the chloride of ethyle is enclosed, immediately after its manufacture
within glass flasks, each containing only the quantity necessary for an operation,
ordinarily 10 grammes.
These flasks, which are of cylindrical form, are terminated by a slender neck
sealed by a lamp after filling. In this state chloride of ethyle can be carried and
stored without fear of alteration.
At the moment of employing it, the slender neck of the flask is broken at the
most contracted point which is indicated by a file mark, and as the chloride of ethyle
boils at +10° Centigrade, it vaporises immediately and issues in a fine jet of
vapour. A liquid jet can be obtained by laying the flask down or by turning it
upside down.
The liquid jet can be strengthened at will by heating the flask more or less by
the hand. It can be stopped by simply placing the finger over the mouth.
The practitioner can thus, without having recourse to any other apparatus, direct
on to the part to be rendered insensible a jet of liquid, the force of which he will
modify and which he will suspend at will.
The quantity of liquid contained in the flask is sufficient for a single operation.

tion, a communication to me from Messrs. Auguste Gilliard, Prosper Monnet, and
Jean Marie Cartier, of 8 Quai de Retz, Lyons, in the Republic of France,
Manufacturing Chemists, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
The chloride of ethyle can be employed as an auæsthetic, but its great volatility

To this end the chloride of ethyle is enclosed, immediately after its manufacture,
within glass flasks, each containing only the quantity necessary for an operation,
ordinarily 10 grammes.
These flasks, which are of cylindrical form, are terminated by a slender neck
sealed by a lamp after filling. In this state chloride of ethyle can be carried and
stored without fear of alteration.
At the moment of employing it, the slender neck of the flask is broken at the
most contracted point, which is indicated by a file mark, and as the chloride of
ethyle boils at +10° Centigrade, it vaporises immediately and issues in a fine jet, of
vapour. A liquid jet can be obtained by laying the flask down or by turning it
upside down.
:
The liquid jet can be strengthened at will by heating the flask more or less by
the hand. It can be stopped by simply placing the finger over the mouth.
The practitioner can thus, without having recourse to any other apparatus, direct
on to the part.to be rendered insensible, a jet of liquid, the force of which he will
modify, and which he will suspend, at will.
The quantity of liquid contained in the flask is sufficient for a single operation.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
A means of preserving and applying chloride of ethyle, by the employment of a
container consisting of a glass flask of any convenient shape and size terminated by
a slender neck, which is sealed by a lamp after filling, and containing only sufficient
liquid for an operation, the said flask thus becoming a veritable surgical instrument
serving for the projection of the liquid or of its vapours in a jet more or less strong,
which is obtained by breaking the end of the slender neck and heating, the flask
more or less by the hand.
