In reporting upon No. 2, I wrote to the gentleman who sent 
me both samples : 
"Dear Sir, — This is a very different guano from that you sent me last 
April. This <iuano is well worth \2>l. 10s. a ton. If both samples were taken 
from same bulk, all I can say is, that the bulk is very unequal in character." 
Before leaving the subject of Peruvian guano, I quote two 
more analyses of samples recently sent to me. Their compo- 
sition was as follows : — 
No. 1. 
No. 2. 
8-70 
17-20 
16-36 
37-89 
19-85 
10- 70 
24-3.5 
22-38 
30-97 
11- 60 
100-00

No. 1 is poor in ammonia, but it was sold at only 8/. 75. 6(/., 
a fair price for such a guano.
