CAPE CANAVERAL, Fla. – STS-126 crew members listen to instructions about landing of the slidewire basket (at right) during emergency escape training from the shuttle and pad. From left are a safety instructor, Pilot Eric Boe, Commander Chris Ferguson and Mission Specialists Heidemarie Stefanyshyn-Piper, Donald Pettit, Sandra Magnus, Steve Bowen and Shane Kimbrough. The crew is at Kennedy to take part in the Terminal Countdown Demonstration Test, which includes equipment familiarization, emergency exit training and a simulated launch countdown. On the STS-126 mission, space shuttle Endeavour's crew will deliver equipment and supplies to the International Space Station in preparation for expansion from a three- to six-person resident crew aboard the complex. The mission also will include four spacewalks to service the station’s Solar Alpha Rotary Joints. Endeavour is targeted to launch Nov. 14. Photo credit: NASA/Kim Shiflett KSC-08pd3413

One can not speak of a neg-ative and positive spark any more than a negative and positivebreeze. The size and strength of the spark is determined by the 56 PRACTICAL ELECTRO-THERAPEUTICS AND X-RAY THERAPY speed of the machine and the size of the ball on the end of the elec-trode. This is an active, energetic current, and is used to great ad-vantage in the treatment of some of the most intractable cases ofrheumatism, etc. This modality requires considerable skill in orderto produce the best results. The electrode should be handled quicklyand regularly, allowing only a single spark to pass between the elec-
