The standard or support for the different screens is identical - the difference being in the shape of the frame upon which the screens are stretched and in the color of the cloth used for screening.

Then in addition to these head screens there is another screen - a combination screen known as "The Century Universal Head and Side Screen." The top of head screen is rectangular and is divided into squares of different density, as shown in the illustration.

The Century Universal Head and Side Screen

This top screen revolves and with it any degree of light intensity can be thrown on any part of the sitter. For example, you arrange the skylight curtains to allow a given amount of light to enter the operating room and to get the desired general direction or proper angle. You then place your sitter and bring this head screen into use. You find that the light is too strong or not quite strong enough after the screen is placed. All that you have to do in this case is to revolve the screen and change the intensity of the light to the desired degree without rearrangement of the skylight curtains.

The side screen can be used as a screen or as a reflector and can be instantly adjusted to any position.

Both models of the Century Head Screen and the Century Universal Head and Side Screen are equipped with improved quick acting clamps or locks and the rods are heavily nickeled. In appearance there is nothing left to be desired and they are well made and substantial throughout.

Pine Tar

An Ohio photographer who read the article for treating chemical poisoning in a recent number writes us his experience which may be of benefit to others similarly affected.

He advises the use of "pine tar" applied to the affected parts before retiring. To keep the pine tar on the hands the use of a pair of loose fitting canvas gloves is advised, and the photographer's faith in this treatment is so strong that it leads him to make the statement that the hands will heal over night. In the morning wash the hands with head-light oil to remove the pine tar. In stubborn cases this treatment should be repeated until a cure is effected.

In closing he says: "My experience is one of the worst in the country. I have spent a few hundred dollars for professional treatment and patent ointments and had no control over the disease until I used pine tar. No doctor or ointment bills to pay simply ten cents worth of pine tar will do it."

Chemical poisoning, while not common and in most cases not serious, should receive prompt attention, as it may cause much trouble and inconvenience if neglected. Consult a good physician in regard to the use of any ointment or other course of treatment before adopting it. The remedy in this article and those given in previous issues are simple and undoubtedly harmless, but it is better to talk it over with the family physician, as self medication without the guiding advice of a doctor is a serious mistake.
