The electro-therapeutic guide, or, A thousand questions asked and answered . 162 THE ELECTRO-THERAPEUTIC GUIDE that will admit positions by the simplest device possible, and itshould have a cross bar holding up the conducting cords. A tube holder sho\tld be made of wood, so as to be as nearly a non-conductor as possible. The accompanying cuts show a small tube, holderfor use on a table, and a large tube holder which stands on the floor. The large tube holder, at the left (p. 161)^ shows a simple chemicalvacuum tube regulating device by means of which the vacuum of a chem-ical regulating tube may be kept at any desired degree, indefinitely, auto-maticalh. With this device the tube may be short circuited, that is, when-ever the vacuum in the tube becomes so high as to back up a spark it willthen pass the current around through the chemical and liberate a little gas,which will lower the vacuum again. This process will be repeated everytime and thus the vacuum be held wherever you want it, automatically. With this simple tube, and holder, and regulator,
