Annual Report for 1892 of the Consulting Chemist. 789 
tion, and, as the following analysis shows, was of low quality and 
extremely dear. 
Moisture 62'75 
1 Organic matter 34'76 
Oxide of iron, &c 4'71 
Sand 7-79 
100-00 
containing nitrogen . . . . .1-28 
equal to ammonia ..... 1-55 
{b) Flue Dust . — A sample of this was sent to me and gave the 
following results : — 
Moisture 22-52 
Organic matter 4-37 
Carbonate and sulphate of lime .... 12-21 
Oxide of iron, &c 9'36 
Insoluble silicious matter 51-54 
100-00 
Such a material has hardly any manurial value at all. 
(c) Lecetic Fertilizer . — This is a material manufactured by the 
Lecetic Manure Company, Newark-on-Trent, and has been, on more 
than one occasion, referred to in the Quarterly Reports of the 
Chemical Committee. It is sold at the price of ?>l. 10s. per ton 
delivered, but is really little more than impure gypsum, and the 
price asked for it is an extravagant one. An analysis of it gave the 
following results 
Moisture . -85 
Sulphate of lime ....... 86 54 
Oxide of iron and alumina 1-18 
Carbonate of lime 2-22 
Alkalies, Szc 2-15 
Sand 7-06 
10000 
Miscellaneous Analyses. 
River Mud . — It is frequently supposed that materials of this kind 
have considerable manurial value, but, however useful they may be 
when close to the spot where they are to be applied, it is seldom that 
they are worth carting any distance. 
A sample of mud from the bottom of a river in Lancashire, and 
subsequently dried, was sent to me for examination. It was estimated 
that the cost of the material upon the farm would be 10s. per ton 
after carting it ten miles.
