Improvement in X-Rays.

Professor Trowbridge has recently succeeded in perfecting a new method of obtaining X-rays which gives promise of very important results. Heretofore the currents of electricity which have been employed in taking the photographs have been uncertain and fluctuating, so that the pictures obtained have frequently perplexed the surgeons who used them. The new method secures a steady current, and the pictures so taken are remarkable for contrast and definition. Under the old method of taking the photographs the muscles and tendons in a body were invisible and a strong light was required in order to see even the bones. With the new pictures very little light is required, and the muscles and tendons show distincly. It is hoped that the new method will be of great service in the study of anatomy.
