hundred stars have thus been taken simultaneously on a plate by a single exposure.

 Orion, of Jupiter's satellites, and of various other objects ; also of the new star in 

 Oiion and of its spectrum, and one plate showing that this star must have been 

 much fainter on November 9, 1885, than when discovered, five weeks later.
