The samples of Huanillos guano analysed by me contained, 
as a rule, somewhat less ammonia, more soluble phosphoric- 
acid, and generally more moisture than Pabillon guanos.

These samples of Puntas de Lobos guanos, it will be seen, were 
poorer in ammonia, but richer in phosphates than Pabillon and 
Huanillos guanos. O 2
