The next and concluding series of analyses of this variety of 

 guano exhibits a very great resemblance in composition to those 

 specimens last described. 



The five first samples were brought me by the importers, 

 Messrs. Gibbs and Son, No. 35 being a duplicate from the ship 

 Manchester, whose analysis was before given (in Table 2). The 

 samples Nos. 39 to 43 were taken from the respective ships by 

 myself, in the presence of Mr. Lawes and of a gentleman of the 

 firm of the importers. I can therefore vouch personally for their 

 authenticity. The other specimens are, with the exception of 

 specimens 34 and 35, from ships lately arrived in the river.
