When these reports are published each contributor. whose report is fairly complete will be mentioned, if possible, and due credit given. It is only by the help of those who can give personal in- formation that data can be secured for the computation of the orbits of meteors. These data are of great scientific value and all reasonable efforts should be made to obtain them.

(5) In what direction did it disappear (or in what direction was it last seen)? For questions 4 and 5, simply N, E, S, or W is not accurate enough, unless these were the exact directions. If compass is used, state it; also if magnetic correction has been applied to compass reading. (6) At what height did it appear? (Use degrees in answering.) (7) At what height did it disappear? (Use degrees in answering.) (8) Did it pass directly o° 2rhead (i.e., through the zenith)? a (9) If not, to which side of the zenith did it go, and how far from it? (Use degrees in answering.) (10) Did it appear to reach the horizon? What sort of a horizon have you? (11) What angle did the p-th of the meteor make with the horizon and in which direction was it then going? / | (12) If you are familiar with constellations describe the path of the meteor through the sky with ref- erence to stars. (13) Did the meteor appear to explode? (14) What was the duration of its flight in seconds? (15) Describe the train if one was left. If it lasted long enough to show drift, most carefully tell in what direction train drifted. Give sketch, if possible, showing this with regard to horizon. (16) What was the duration of the train in seconds? (17) Did you hear any sound? How long after seeing the meteor was it before you heard this : sound? Did you hear an actual explosion? How long after seeing the explosion was it before you heard it? (18) Of what color was the meteor? (19) What was the size of the meteor? (Compare it with the Moon or with a planet or star.) (20) Was more than one body seen before the explosion (if any)? (21) What was condition of sky at time? - (22) Give names and addresses of others who saw the meteor.
