Philosophical Transactions of the Royal Society of London^ for 

 1826. Parts I. and 11. 



The first part of the Philosophical Transactions for the pre- 

 sent year is occupied by Mr. South's observations of the apparent 

 distances and positions of 458 double and triple stars, made in 

 the years 1823, 1824, and 1825 ; together with a re-examination 

 of 36 stars of the same description, the distances and positions 

 of which were communicated in a former memoir by himself and 

 Mr. Herschel. Of the results of these observations, it is of 

 course impossible to give any general idea within the space to 

 which we are limited in this article : for powerful testimony to 

 the importance of the subject, and to the success with which 

 Mr. South's labours in this branch of astronomy have been 

 attended, we may refer the reader to the last number of the 

 Annals. He will there find the address lately delivered by the 

 President of the Astronomical Society, on presenting the gold 

 medals, awarded by that body, to Mr. Herschel, the author of 

 the memoir before us, and Prof. Struve, for their zealous and 

 indefatigable pursuit of this subject ol' J)oubk Stars,
