II. Preliminary note on the continuity of the liquid and gaseous states of matter

For several years past we have been engaged in an examination of the behaviour of liquids and gases through wide ranges of temperature and pressure. The results of our experiments with ethyl alcohol have recently been published in the ‘Philosophical Transactions;’ those with acetic acid in the ‘Journal (Transactions) of the Chemical Society; and the Royal Society have in their hands a similar investigation on ether. We have also finished a study of the thermal properties of methyl alcohol.

II. Evaporation and dissociation. Part V. A study of the thermal properties of methyl alcohol

This is a continuation of the investigation in which the authors are engaged. The measurements include the expansion of the liquid, the pressure of the vapour, and the compressibility of the substance in the gaseous state; and from these are deduced the densities of the saturated vapour and the heats of vaporisation.

A Study of the Thermal Properties of Ethyl Oxide.

A year ago, a paper was communicated to the Society on the behaviour of ethyl alcohol when heated. A similar study of the properties of ether has been made, in which numerical values have been obtained exhibiting the expansion of the liquid, the pressure of the vapour, and the compressibility of the substance in the gaseous and liquid conditions; and from these results, the densities of the saturated vapour and the heats of vaporisation have been deduced. The temperature range of these observations is from —18° to 223° C.

2. On the Effects of Chloroform, Ethidene Dichloride, and Ether on Blood-Pressure

Dr Coats stated that this communication referred to part of an investigation on the physiological action of anaesthetics, undertaken, at the request of the British Medical Association, by Dr Ramsay, Dr MKendrick, and himself.
