Send your typewriters to war. At Universal City, California, Maria Montez, glamorous Latin-American movie star, and Gloria Jean, typical of young America in Hollywood, helped collect over one hundred typewriters for the Army, Navy, and Marines. Only machines manufactured since January 1, 1935 were commandeered; no portables were wanted. A telephonic dictation room is being set up whereby busy executives can pick up the telephone, dictate their mail to a centrally located room which insures prompt typing of their letters, and at the same time more correspondence can be handled with lesser number of typewriters

eother terminal of the apparatus is connected to a metal handle whichthe patient holds in his hand. 52 Anthony Matijaca Due to the large amount of current (300 to 1000 milliamperes) em-ployed in this treatment, the patient feels a gentle warmth beginning atthe wrists, gradually extending up the arm to the axilla and over theentire body. The current traversing the patient can be measured introducing aspecial hot wire milliamperemeter in that part of the circuit which con-nects the metal electrode which the patient holds in his hand. In order to demonstrate the amount of current with which the pa-tient is charged, while under this treatment, it is only necessary to havethe patient illuminate a 16 candle power, 110 volt incandescent lampthrough his body, by introducing it into the circuit in the same way as amilliamperemeter. AUTO-CON DUCT ION is administered by placing the patient inside ofa large solenoid, or a cylindrical wire cage, without connecting him inany way with it. (Fig. 18.)

Fig. 17—Patient undergoing auto-condensationtreatment The cage is connected to the apparatus, and the current travels com-completely around the outside of the cage. Thus travelling through thecopper wire, this current discharges itself from all sides into the bodyof the patient, who thus receives a full body treatment. Auto-condensation and auto-conduction treatments are usually ad-ministered for from 10 to 30 minutes, and are given daily at first innearly all cases, gradually decreasing as the patient improves. Direct Application of DArsonval Current DiathermyDArsonval current directly applied by means of two metallic elec-trodes in passing over a small cross section through the internal tissueof the body, generates a purely mechanical heat, by overcoming the re-sistance of the tissue, in the same way as electricity heats the resistancewire in passing through it. The higher the frequency and stronger thecurrent, the greater the heat production. Electro-Medicine, Electro-Surgery and
