Electricity

While attending the meeting of the Xeurological club last Saturday after noon, at the electro-therapeutical laboratory, one or two remarks that were let drop suggested to us that some work was being done in that laboratory, and by the professor in charge, that was not receiving the share of credit that was its due. Dr. Ilerdman dropped the retnark that they aimed to Ilústrate there every known therapeutic use of electricity. That is quite a statement, and we involuntarily cast our eyes around the rooms. It is not mach of a louking place. A moderate sizd room in the oíd medical building, showing very plainly the effects of years of wear and tear, lined around the walls with cases containing various electrical appliances, and crovvded with tables, showing very clearly the fact that they needed more, yet we flnd that some great things are being done here. We flud that the students are required to gain au intímate knowledge of the different forms of electriciiy.and and the methods of generating the different forms of current. Many of the devices in use are made right in the Uniyersity, and the student is thus made capable of providing himself with necessary appliances for use in his practice, under circumstances that would deter many. Being thus thoronghly prepared, the student is given a hospital course for the application of his knowledge. That these results are appreciated by the pro fession is evi denced by the fact that Prof. Abel of Jolms-Hopkins University, who studied for yeara in Germany, says that the work being done here surpasses that being done in the laboratory of the noted Erb of Vienna. A remark dropped by Dr. Ilitchcock of Detroit, brought out an interesting state of facts. Dr. Ilerdman was using and explaining what is known as the "Mclntcöh Current Controller," when Ir. Ilitchcock said, "It ought to be called the Ilerdman Controller." The wide and extending use of electricity, and the expensivencs3 of most of the equipments obtauiable, inipressed Dr. Herdman with the neeessity of linding some inexpensive means of using the commercial plants now found in almost every cityt He ac cordingly devised this controller. It is a small instrument which can be at tached to any incandescent light dynamo, alternating or direct, or a current derived from a storage or primary battery. The original voltage being known. Iho pressure employed at any instant can be known. It is increased or decreased in a decimal ratio and measured by a clearly marked scale. By its ine all danger of shock to the patiënt by an exeessive current is re moved. The current can be increased gradually, out steadily, from one that is imperceptible, up to all that the patiënt can bear. It is portable, and makes possible the use of electricity in thousands of cases where it would be otherwise imp03sible. Tho only fault to be found with Dr. Ilerdman is that he did not take the credit for it to which he, and through him the University. was duly entitled.
