This is completely established by M. Marians de Riviero, who, 

 in a Spanish treatise, a short extract of which is given in Fe- 

 russac^s Bulletin, sect. i. t. xi. p. 84, mentions, that the Spa- 

 niards have entirely forgotten the wise provisions of the Incas, 

 to secure the preservation of the precious manure. The Peru- 

 vians begin now to discover their error, and look forward with 

 anxiety to the period when the guano will no longer suffice for 

 the wants of husbandry. In fact, the discovery of new beds of 

 the brown guano, which is of oldest formation, daily diminishes 

 in frequency, and the production of the white guano, that which 

 is still forming, has suddenly decreased, since the unlimited free- 

 dom of trade has attracted so many vessels to the coast, which 

 scare away the flocks of birds which used formerly "to roost upon 

 the rocks and islands. 



Notwithstanding all these disadvantages, very lately the an- 

 nual product of brown and white guano, amounted to about 

 6300 tons, for which the duty has been about £ 40,000 Ster- 

 ling per annum, paid at the different ports from which it is 

 transported into the interior. 



M. Buckland prefers for the Guana the name of Ornithoco- 

 prus. 



On the Changes the Animal Secretions undergo during Cholera

 body undergo during cholera, from the 6th number of the An- 

 nalen der Physih und Chemiey 1831, as very few minute^ inves- 

 tigations of this nature have been recorded in the many works 

 on this subject of cholera, which have been published in this 

 and other countries ; and it is of the highest importance that 

 every information should be made public concerning the nature 



" Near Villacori the ancient Peruvians also used as manure the pilchards 

 {Clupea Sardim)i thrown up by the sea.
