    of cases these changes are almost inappreciable. I have never been able to detect any irregularity in the rhythm, nor, as a general rule, has any cough, laryngeal spasm, or bronchial irritation been set up. In speaking thus of the effects upon the respiration, I would remind you that my remarks apply, only to the special methods adopted in the production of anesthesia for the purposes of the dental surgeon, and are not in any way applicable to the effects produced when the anesthesia is prolonged. There can be no doubt, I should think, that the cardio-vascnlar or circulatory system is much disturbed during the inhalation of bromide of ethyl. The primary flushing of the face is, I think, a pretty constant phenomenon, though it may be but momentary in its duration; this elfect is very similar to that produced by nitrite of amyl, and, T should fancy, may be explained in the same way, i.e., arterial dilatation with consecpient fall of blood pressure. This fall in blood pressure may, no doubt, to a certain ex- tent, in itself account for the diminution iii force, and increased frequency of the heart beat, as observed at the radial pulse. It is highly prob- able, however, that other factors are at work, for to the flushing quickly succeeds a pallor, and the heart’s action tends to become more feeble, slower aud irregular.
