The sample marked "Park View" contained 5-95 per cent, 
of salt. 
Mr. Hedges asking an opinion of the market value, Dr. 
Voelcker wrote, May 20th : — 
" Taking into consideration the fact that the bones, if pure, would contain 
about 60 per cent, of phosphate of lime, you would be, I think, justified in. 
claiming a reduction of at least 11. per ton for the difference, provided you 
bought the bones as a pure article. Will you kindly fill up and return to 
me the form I lately forwarded ? — Yours faithfully, 
" J. Augustus Voelcker*" 
The following letter then passed : —

" Hoping this will be satisfactory to you, — I remain, yours truly, 
«' H, Hedges."
