A printed copy of the above stated questions will be sent hereafter 

 from this ofifice to every ixppHcant for analysis free of charge, to be 

 answered by him according to his best information, before his 

 request can be considered. 



We occasionally receive samples that bear no mark of identifica- 

 tion and therefore have to be thrown away. For this reason we 

 have had shipping tags printed and applicants for analysis will upon 

 request be furnished printed shipping tags which will facilitate the 

 shipping of samples and insure their safe delivery and recognition.
