Fig. 9 shows a slight dilatation of the intestinal wallaftcr administration of ethyl iodide, and in this instance the dilatation appears to correspond with the tall of blood pressure. My clinical experience, which only extends to ethyl chloride and ethyl bromide, bears out the results obtained by physiological experiment.

It is stated by many anaesthetists that * ethyl chloride is a cardiac stimulant and that if a full dose is administered it dilates the peripheral arterioles.'' The stimulating effect upon the heart is at best only slight and transitory, and is followed by a much more significant and lasting depressant effect. As we have seen there is only a passive dilatation of peripheral arterioles, and in full doses the blood is drained from the splanchnic area and also from the limb. I. Knight, Brit.
