3. Lieut.-Col. Milligan, of Caldwell Hall, Burton-on-Trent, for- 
warded for analysis, on April 20, a sample of what he had purchased 
as “Blood and Bone Manure,” and which cost 6 1. per ton delivered. 
The vendors were Messrs. E. Dean & Sons, Gibbons Street, Ashton 
New Road, Bradford, near Manchester. 
Messrs. Dean & Sons, in their circular, quoted, under the heading 
of “ Blood and Bone Manure,” two different manures, one at 51. per 
ton, and the other, which was stated to be “ specially prepared, of 
extra quality,” at 6Z. per ton. The latter was recommended in a 
letter from the vendors, they enclosing the following certificate 
relating to it : — 
Chemical Laboratory, Gibbons Street, Bradford, Manchester. 
Harry Grimshaw, F.C.S., late Demonstrator in Chemistry, 
Owens College, Manchester, Mem. Lit. Sc Phil. Soc., Manchester. 
Below please find results of our analysis of the sample of manure which 
you handed to me : — 
Moisture ......... 20-09' 
Organic matter 39 - 25 
Sulphate of lime 8 - 14 - 100-00 
Alkaline salts ........ 1-13 
Mineral matter ....... 31‘39, 
containing nitrogen equal to ammonia . . . 5 032 per cent 
containing phosphoric acid. .... 8 060 „ 
The. approximate value of the 
percentages is as follows : — 
Organic matter 
Sulphate of lime 
Phosphoric acid 
Alkaline salts 
Ammonia

This manure is very good value for 71. per ton, and should work well 
without either requiring the addition of superphosphate or ammonia salts. — 
I am, yours faithfully, H. Grimshaw.
