380 Notes on tlie Composition of some Samples of Silage. 
5. Mr. James Chalcraft sent from East Worldham, near 
Alton, Hants, a sample of manure purchased as the best 
Peruvian guano at 13/. 10s. per ton. 
Dr. Voelcker gave the following results of analysis, and his- 
report upon it : — 
Moisture 10-90 
* Organic matter, &c 35 "72 
Monobasic phosphate 9-87 
Equal to tribasic phosphate of lime, renderedK^- .-y 
soluble ^(.iO 40J 
Insoluble phosphates 6-59 
Sulphate of lime, &c 25'32 
Sand 11 -GO 
100-00 
* Containing nitrogen . . . . , . . . ,5-08 
Equal to ammonia 6-17 
Dear Sir, — The mixture which you sent me is not best Peruvian guano,, 
but a regular artificial compound manure, for which I should be sorry to- 
have to pay more than 10^. a ton. 13?. 10s., in my judgment, is a most 
extravagant price for the manure which 5'ou sent me for analysis, and which, 
ought not to be sold as best Peruvian guano. — Yours faithfully, 
Augustus Voelcker. 
No further information has been obtained from the purchaser.
