AB In the use of the polygraph we have found that unless plenty of hands are available, the application and operation of the sphygmograph is a trial to the patience of both patient and technician. Some time ago R. H. Halsey1 described the use of an Erlanger capsule for obtaining a brachial arteriogram, which we tried with indifferent results. We were unable to obtain a bulb ofjust the right elasticity to transmit properly the pressure changes. We believe we have found a substitute for the Erlanger capsule that will serve all purposes admirably, and that can be inexpensively put together in any laboratory.A graduate, about 5 cm. in diameter, may be used and cut so as to secure a cylinder, 9 cm. long. The two ends (Fig. 1 A) are plugged with rubber corks, each perforated by a single opening. Glued in the hole in one cork is the
