NOTES AND QUERIES. 



XYLO-IODIDE OF SILVER, exclusively used at all the Pho- 

 tosraphic Establishments. — The superiority of this preparation is now universally ac-

 uniformly such perfect pictures, combined with the greatest rapidity of action. In all cases 

 where a quantity is required, the two solutions may be had at Wholesale price in separate 

 Bottles, in which state it may be kept for years, and Exported to any Climate, full instructions 

 for use.
