Opkning Address of the Winter Session at the North-East London Post-Graddate College, October 27th, 1910. • SIR LAUDER BRUNTON, Bart., M D., D.Sc,, F.R.C.P., F.R.S. consulting PIITSICIAN to ST. BARTHOLOMEW’S HOSPITAL. Mr. President and Gentlemen,—I thank you for the honour you have done me in asking me to address you to night, and also for the choice of subject which you have given me. I am informed that you would like me to speak on the clinical aspects of blood pressure, a subject in which I am particularly interested. It is said, and I believe with truth, that when a man grows old he reverts to the subjects of which he was fond in his youth, and on the 25th of next month it will be exactly forty-five years since I made my first experiment on blood pressure under the guidance of my friend, the late Professor Arthur Gamgee. At that time instruments for recording blood pressure were very few in number altogether, and there was not such a thing in the three kingdoms. The apparatus that I used was not a recording one, and was of the very simplest kind. It was a crude imitation of Marey’s haemodynamometer, and consisted of a pomatum bottle, half filled with mercury, and with three holes bored through the cork. In the first of those was fixed an upright tube, about 18 in. long, in which the mercury oscillated freely, and gave the maximum and minimum pressures. The second was similar in size, but had a constriction at one part, so that the mercury oscillated very little in it, and thus the mean pressure was indicated. The third tube was bent, and communicated with the * The latter part of this address was also given at the meeting of the Beading Pathological Society on October 20tb, 1910.
