EEEATA IN PROFESSOR BISCHOF'S MEMOIES. 



[We insert for the use of those who are more particularly interested in the memoirs by 

 Professor Bischof on springs, volcanos, earthquakes, &c, which have appeared in our 

 Volumes from XX. to XXIX. inclusive, a carefully prepared list of errata of the whole 

 series. The errors have chiefly arisen from the conversion from one scale to another of 

 the extremely numerous thermometrical observations.]
