some remarks having been made upon the desirability of print- 

 ing Dr. Holyoke's meteorological journal in extenso, the origi- 

 nal manuscript, along with Professor Nichol's letter, was re- 

 ferred to a committee, consisting of Messrs. Hale, Paine, and 

 Gould. 



Mr. Everett read extracts from a letter of Professor Schu- 

 macher of Altona, stating the conditions required to be ob- 

 served by the candidates for the medal awarded by the king 

 of Denmark to the discoverers of telescopic comets. As the 

 conditions in respect to the immediate transmission of intelli- 

 gence to the proper persons are indispensable, and appear not 

 to be well known in this country, Mr. Everett read a transla- 

 tion from the original German, in the Astronomische Nach- 

 richten, No. 400, which, for the sake of wider dissemination, 

 is herewith given in the subjoined note.* 



* A gold medal of 20 ducats' value was offered by the predecessor of the late 

 king of Denmark to the discoverer of a telescopic comet. This foundation was 

 confirmed by the late king, by whose authority the following regulations were 

 established : — 



1. The model will be given to the first discoverer of any comet, which at the 

 time of its discovery is invisible to the naked eye, and whose periodic time is un- 

 known. 



2. The discoverer, if a resident in any part of Europe except Great Britain, is 

 to make known his discovery directly to Mr.. Schumacher at Altona. If a resi- 

 dent in Great Britain, or any other quarter of the globe, except the Continent of 

 Europe, he is to make his discovery known directly to Mr. Francis Daily, Lon- 

 don. — [Since Mr. Baily's decease, G. B. Airy, Esq., Astronomer Royal, has been 

 substituted in this and in the 7th and 8th articles of the regulations.] 



3. This communication must be made by the first post afler the discovery. If 

 there is no regular mail at the place of discovery, the first opportunity of any 

 other kind must be made use of, without waiting for other observations. Exact 

 compliance with this condition is indispensable. If this condition is not complied 

 with, and only one person discovers the comet, no medal will be given for the dis- 

 covery. Otherwise, the medal will be assigned to the discoverer who earliest 

 complies with the condition. 



4. The communication must not only state as exactly as possible the time of 

 the discovery, in order to settle the question between rival claims, but also as 

 near as maybe the place of the comet, and the direction in which it is moving, as 

 far as these points can be determined, from the observations of one night. 



5. If the observations of one night are not sufficient to settle these points, the 

 annunciation of the discovery must still be made, in compliance with the third
