812 Annual Report for 1893 of the Consulting Chemist. 
A was an utterly worthless material as a manure, and B nearly 
so, and neither was basic slag at all, a substance which should con- 
tain about 17 per cent, of phosphoric acid. 
Nitrate of Soda . — An adulterated sample of this manure was 
sent me, which analysed as follows : — 
Moisture G - 59 
Chloride of sodium (common salt) .... 14-46 
Sulphate of soda 11-20 
Nitrate of soda 6775 
10000 
This was accordingly adulterated to the extent of one quarter 
(25 per cent.) with common salt and sulphate of soda. 
Pigeon Manure . — An analysis of a sample sent me gave the 
following : — - 
Moisture I860 
1 Organic matter 58-55 
Phosphate of lime ....... 5-39 
Alkalies, &c 446 
Sand 13-00 
100-00 
1 containing nitrogen 3-49 
equal to ammonia . . . . . . 4 - 24 
This manure could, I was told, be obtained at a cost of about 
70s. per ton delivered, but this would appear to be rather above its 
value, though it was dry and in good condition. 
Refuse Materials . — Worthless or nearly worthless materials con- 
tinue, as before, to be foisted on the farmer. The following are 
instances : —

was not worth 
paying carriage upon. 
B also cost 3/. per ton, and was still worse. 
I append the list of analyses made in the Society’s Laboratory 
during the past year.
