Peruvian Guano. 

 The samples of Peruvian guauo which have been subjected 

 to an examination during the past year, were taken at differ- 

 ent periods of the season, and in different sections of the 

 State. Nos. I. and II. were offered for sale in the month of 

 April by dealers in Boston, and Nos. III. and IV. in June by 

 parties in Worcester. 



Raw Peruvian Guano. 



I. 



II. 



Phosphoric acid, 



Nitrogen, . . . . 



Potassium oxide. 



Insoluble matter (sand, etc.). 



The analytical results prove that both specimens are of a 

 good quality, and apparently from one and the same cargo — 

 Guauape guano.
