✦ Synopsis
The ever increasing number of routine samples sent to the laboratory for physiologic test has made it necessary to increase the efficiency of our apparatus to economize in time and space and prevent routine from interfering with experimental or research work. FIG. 1.-Kymograph arranged for making blood-pressure tests on four animals at one time.

I n a previously published paper,' I described an apparatus with which it is possible for one person to carry out blood-pressure tests on four animals at the same time and record all the tracings on one kymograph. This improved kymograph finds its greatest value in blood-pressure tests which, of all the physiologic methods, consume the greatest amount of time. This is true particularly in the blood-pressure test for ergot in which it is necessary to check the results on two or three dogs and, on account of cumulative action, to allow one to one and a .~ -~ _ _ ___ -. ~~ ~ * Read before Scientific Section, A.
