Not illustrated. 1889 Excerpt: ...The force of the wind had been broken. Edison's difficulty seemed to increase as the precious moments of total eclipse drew near. At five minutes past 3 o'clock, the sun's disc was seven-eighths covered, and the country around was shrouded in a pale grayish light, resembling early dawn. At a quarter past 3 darkness was upon the face of the earth. The few moments for which the astronomers had traveled thou- sands of miles had arrived. Still Edison's tasimeter was out of adjustment. All the other instruments were in excellent working order. Totality had brought with it a marked cessation in the force of the wind. Edison worked assiduously, but the tasimeter would not come to a proper condition. At last, just as the chronometer indicated that but one minute remained of total eclipse, he succeeded in concentrating the light from the corona upon the small opening of the instrument. Instantly the fire ray of light on his graduating scale swept along to the right, clearing its boundaries. Edison was overjoyed. The experiment has shown the existence of about fifteen times more heat in the corona than that obtained from the star Arcturus the previous night. Edison's tasimeter showed its power to measure the corona's heat. It, however, was adjusted ten times too sensitively. Never having used it before for a similar purpose, he had no means of telling the degree of sensitiveness necessary. The heat from the corona threw the ray of light entirely off the scale, and before he could make the second test the eclipse had passed away. The experiment demonstrated that, compared to some of the fixed stars, the corona's heat was much greater. Basis of the Tasimeter. The tasimeter is a modification of the micro-tasimeter which is the outcome of Mr. Edison's experiments wi...
