Fine Bones of G. B. Root of NorthborougTi, Mass. 

 (Messrs. J. 85 J. A. Rice, Worcester, Mass.) 



These samples of ground bones represent tlie average com- 

 position of good pure articles of their kind : their composi- 

 tion varies within the usual limits of more or less moderately- 

 rendered bones. The texture and the general appearance of 

 No. III. makes it doubtful whether it has been rendered at 

 all ; it was also somewhat coarser than Nos. I. and II. The 

 retail price of ground bones has been from forty to fifty dol- 

 lars per ton of two thousand pounds.
