PROFESSOR HEIS'S STAR ATLAS. 



A NEW star atlas of high scientific and practical value has 

 been recently published by Professor Heis, of Mtinster. This 

 work consists of twelve sheets, and contains 5421 stars and 

 nebulae i. e., all that are visible to the sharpest vision in the 

 northern hemisphere. While 'in many respects similar to the 

 standard atlas of Argelander (his Tlranometria A'^o?;a), it dif- 

 fers, and is perhaps an improvement on it, in that it contains 

 many more of the fainter stars, and especially that the Milky 

 Way is skillfully delineated, with all its variations of outline 

 and brightness. Such an atlas becomes invaluable to those 

 who interest themselves in the recently developed department 

 of meteoric astronomy. 



AMERICAN STAR CATALOGUE. 



The largest catalogue of stars ever prepared in America 

 has been published by the United States Naval Observatory 

 at Washington. 



This work embodies all the valuable observations made 

 since the foundation of the observatory, in 1842, with the 

 meridian instruments, consisting of the Avork of the well- 

 known astronomers Coffin, Hubbard, Ferguson, Newcomb, 

 Hall, Harkness, and Yarnall. Over fifteen years of labor have
