1, the undersigned, hereby guarantee to deliver, in a sufficiently 
dry and powdery condition to admit of ready distribution by the 
drill or for hand-sowing, tons of dissolved bone at 
per ton, which shall contain — 
1. per cent, of soluble phosphate of lime. 
2. per cent, of iiisolub/e phosphite of lime, present entirely 
as boiled or raw bone, and not as bone-ash, coprolites, or other 
mineral phosphates. 
3. per cent, of nitrogen equal to per cent, of ammonia. 
In case of deficiency I agree to allow for each unit per cent. 
which the dissolved bones are found on analysis to contain 
less than the guaranteed percentage of soluble phosphate of 
lime in a fairly drawn sample, taken within three days after the 
delivery of the bulk : — 
1. Of soluble phosphate per ton, 
2. Of insoluble phosphate per ton, 
3. Of ammonia per ton. 
Signature of Vendor 
N.B. The sample for analysis should be taken by emptying 
several bags, mixing the contents together, and filling two mustard 
tins full in the presence of a witness ; both to be sealed, one to 
be forwarded to for the determination 
of its constituents, and the second to be kept for reference.
