Operation of the Static Machine in Summer.—I have often been spoken to by physicians about the trouble they experience in getting an adequate current into the patient during rainy seasons in July and August. In some cases their machine gives a good discharge between the sliding poles, but little or nothing reaches the patient. It is difficult to say at a distance what may be the cause of the trouble in any given case. Non-experts sometimes think their machines are in perfect order when they are actually the reverse. BThey may also regard the conditions of the room favorably when the trained operator of static apparatus would at once detect a weak point. If the machine and room are dry and in good order the work done in July and August should rarely disappoint. In my own case I have entire confidence that my machine will work on every day in the year, for if it fails for a moment I speedily correct the trouble. The mastery of the conditions which en- ables me to do this can be acquired by other physicians without a doubt.' I have never failed to quickly discover the cause of defective action in the case of machines in other offices when I have been able to make a personal examination, even through previous correspondence failed utterly to suggest the trouble. It should be remembered, however, that few owners of static machines have been carefully instructed in their management. They have usually bought an apparatus and picked up hap- hazard their slender stock of knowledge about it. The machine is far too valuable to be viewed in an indifferent manner and it will well repay the time and cost to procure the best instruction possible. Motor.—The consideration of motor power in connection with the static apparatus is quite important. Physicians in different localities have different methods available. Some will find it necessary to employ water as the power. Some have
