A cablegram from St. Gobain, Prance, h;is brought the 

 gratifying news thai the glass disk for the 100-inch Hooker 

 Reflector, has been successfully cast. It will starl upon its 

 Long journey so soon ;is it can be securely packed in its iron 

 case, and upon its arrival in Pasadena. Professor Ritchey will 

 immediately commence its grinding, polishing and figuring 

 with the new machinery by him devised. This labor, and the 

 construction of .the new housing and mounting upon Mount 

 Wilson, will require about three years, and an expenditure of 

 half a million dollars, hut we can await patiently the comple- 

 tion of an undertaking nowhere paralleled on our globe, and 

 such as the most vivid imagination of mankind has never 

 it ofore conceived. 



The large amount of matter in this number of the Bulletin 

 has expanded its size so far beyond the usual dimensions that 

 the record of the Transactions of the Academy is necessarily 

 omitted. It will be included in the Bulletin for Jul v.
