 reported to its Secretary. The first thought of observers of 

 all classes is to communicate with the Smithsonian Institution, 

 and this is also an excellent witness to the general intelligence 

 of the country, as has been remarked by all who have had 

 occasion to observe how widely this desire is spread and in 

 what unexpected places it is found. 



STAR- MAPS 



A COMMITTEE of the Connecticut Academy of Sciences, Pro-

 convenient star-map of the north polar regions to aid in the 

 observations of the August meteors, which was widely circu- 

 lated at the expense of the Smithsonian Institution ; as well 

 as a copy of the smaller map, from the Toronto observations, 

 designed for observations of the aurora. Many observers 

 took part in the charting of meteors, and their results have 

 been discussed and published by Professor Newton and
