s of paraffine and beeswax.

19. Wear woolen clothes if possible. Cotton clothing should be dipped
in a strong solution of baking soda and dried. Wear a flannel apron
covered with sacking.

20. Keep a bottle of strong ammonia handy. If you should spill acid on
your clothes, apply some of the ammonia immediately to neutralize the
acid, which will otherwise burn a hole in your clothes.

21. Keep a stone, earthenware, or porcelain jar filled with a solution
of washing soda or baking soda (bicarbonate of soda). Rinse your hands
in this solution occasionally to prevent the acid from irritating them.

22. If you should splash acid in your eye, wash it out immediately
with warm water, and drop olive oil on the eye. If you have no olive
oil at hand, do not wait to get some, but use any, lubricating oil, or
vaseline.

TESTING THE ELECTRICAL SYSTEM

"Out of sight, out of mind," is a familiar saying. But when does it
hold true?

What about the battery repairman? Are the batteries he repairs "out of
sight, out of mind?" Does his responsibility end when he has installed
a battery on a car? Suppose he put a battery in first class shape,
installs it on a car, and, after a week or two the battery comes back,
absolutely dead? Is the battery at fault, or is the repairman to
blame for neglecting to make sure that the battery would be given a
reasonably good chance to give good service and receive fair treatment
from the other part of the electrical system?

The actual work on the battery is finished when the battery cables are
fastened to the battery terminals. But real battery SERVICE does not
end there. The battery is the most important part of the electrical
system of a car, but it is only one part, and a good battery cannot be
expected to give satisfactory service when it is connected to the
other parts of the electrical system without making sure that these
parts are working properly, any more than a man wearing new, shoes can
step into a mud puddle and not have his shoes covered with dirt.

The battery functions by means of the current which flows through it
by way of the cables which are connected to its terminals. A battery
is human in many respects. It must have both food and exercise and
there must be a proper balance between the food and the exercise. Too
much food for the amount of exercise, or too much exercise for the
amount of food consumed will both lead to a lowering of efficiency,
and disease frequently re
