    breathlessness, we may say that in cholera-collapse there is a primary asphyxia, and a secondary apnoea consequent on the blood-stasis in the arterioles before it can reach the capillaries to be aerated. On the other hand, in asthma there is a primary apnoea caused by bronchial spasm which cuts off the air from the pulmonary vesicles, and a secondary asphyxia the result of arterial contraction. In conclusion, Sir, I venture to express a hope that the brief survey which we have taken of some of the pathological phenomena with which the muscular arterioles and the vaso-motor nervous system are intimately and obviously concerned has not been without interest even for this learned audience, to whom I desire to offer my cordial thanks for the attentive hearing with which they have favoured me.
