therefore of less pecuniary value than those our Association presumably 
bought. You bare taken a most prudent step in forwarding a sample to the 
analyst, and our directors will thank you most cordially for it. They will 
also indemnify your employer for any loss occasioned by the infejior 
quality of the bones supplied to you. To ascertain the difference in money 
value between the bones you received and those you should have received, 
it will be necessary to supply Dr. Voelcker with the following information : 
"Desciiption of goods — pure raw bones. 
"Price — 6^. per ton, less 2s. 6c?. per ton for ca&bj carriage paid Carriage 
from 4s. to 5s. per ton. 
"Quantity purchased — four tons. 
" Time of purchase — April 28 ; 
and any other particulars, and he will inform you what the pecuniary 
difference is. When this is done and you make a demand on our Associa- 
tion for such sum as may be due, then our directors will proceed to recover 
the same from the firm who have contracted to supply pure raio bones.
