1 In my last report (IV.) was published an analysis of Ammoniated Super- 

 phosphate of Messrs. O. Foote & Co., which does not apply to that article 

 as offered for sale in the general market. My sample was collected in the 

 storehouse of Messrs. W. H. Bowker & Co., where it served for the manufac- 

 ture of more compound fertilizers; a fact which came to my knowledge too 

 late to' prevent the mistake. I have no reason to doubt that the fertilizer sold 

 under that name by the successors in the business, Messrs. H. B. Aruokl & Co. 

 of Boston, corresponds in its composition with the analytical statement which 

 accompanies each package.
