9. Mr. Thomas Rogerson, of Heath Side Farm, Cheadle, 
Manchester, sent on May 7, 1889, a sample of manure described 
as " Bone Phosphate." The material had been purchased from 
the Manchester Phosguano Co., 41 Corporation Street, Man- 
chester, who were the manufacturers ; and when sending it for 
analysis Mr. Eogerson wrote : — " It was represented to me to 
be worth 31. 10s. per ton, but owing to the Local Authority 
condemning the works as a nuisance, they were selling at 35s. 
2)er ton, in order to clear out." 
Dr. Voelcker gave the following analytical report : — 
" May 24, 1889.

"There is nothing to warrant this, a refuse material, being called hone 
phosphate ; it has only 8 per cent, of phosphate, and practically no ammonia, 
10s., instead of 3/. 10s., would be more like its value ; but 1 would prefer to 
have nothing to do with it. "J. Augustus Voelckeb." 
10. Mr. R. S. Balden, of The Grove, Hanging Heaton, near 
Dewsbury (afterwards of Hollinghurst, Netherton, Wakefield), 
sent on May 9, 1889, a sample of oil-cake for analysis. Two 
tons had been purchased from the Dewsbury Pioneers' In- 
dustrial Society, Limited, at 9/. per ton delivered at the farm, 
and Mr. Balden said that he would probably receive a discount 
of 2s. Sd. in the pound at the half-year when the profit was 
declared. Mr. Balden could not obtain from the Dewsbury 
Society the name of the manufacturers, but stated that the 
cake was branded " D. S. Cake," and was made in Hull,
