Equalized Peruviati. Guano. 
This term refers to Guanos which originally 
contained less ammonia than those of the Peru- 
vian type, but which have had tlie ammonia 
made up to the standard of good Peruvian 
guano, by the addition of sulphate of ammonia. 
It should contain not less than 8 per cent of 
ammonia The following is an analysis by 
Tatlock :—

Meat Guano. 
I have already referred to tlie form of Meat 
Guano or Meat Meal valued only for its nitrogen- 
ous contents. Another fonn of this Substance is 
sold, which includes a variable proportion of bones, 
under the name of mi.Kcd scrap. It ought to con- 
tain from 7 to 8 per cent of ammonia and from 30 to 
40 per cent of phospliates. Both the phospliates 
and the ammonia, however, are often much 
lower than this. In the following example the 
phosphates are particularly deticient : —

American animal Guano, from tinned meat

This class of manures is prepared by htatiug
