It consists of a small metallic box containing three small spiral springs, which serve to give the membrane covering it a certain tension. The membrane bears on its outer side a small button or plunger which can be applied to the skin over the artery. The pulsatory movements of the arterial wall are taken up by the plunger and are conveyed by the tube leading from the chamber of the box to the recording tambour. The whole apparatus is fastened to the neck by means of the hoop and screw. With well-constructed apparatus this method of registration has been foundto be very exact. But not all tambours are so constructed, and it is necessarybefore undertaking any exact determinations to prove the apparatus. A very.
