" When you have received Dr. Voelcker's analysis I shall be glad to see it ; 
I feel assured that it cannot be such as to justify the hasty condemnation 
conveyed by his letter. — Yours faithfully, Henry R. Hart."

In reply to further enquiry. Dr. Voelcker wrote : — 
" May 9th, 1885. 
"Dear Sir, — I am much obliged for your kind replj- and enclosures. As 
regards the value of manure, though I do not know exactly what the carriage 
amounts to, I may say that 11. 15s. per ton nett cash is too dear for such a 
sample, which, independent of carriage, is not worth above 6/. 10s. a ton for 
cash. — Yours faithfully, J. Augustus Voelcker." 
" G. Ingram, Esq.""
