An excessively impure cake, containing a large admixture of weed seeda, 
amongst which corn-cockle is prominent. I would advise you on no account 
to use such a cake. 
In reply to inquiries, Mr. Wickham said that the cake was pur- 
chased frcni a dealer who stated that it came from Hull, but refused 
to give the name of the manufacturers. Mr. Wickham, in ordering 
the cake, did not specify for pure cake, but merely said, " Send a 
ton of oil-cake." Ultimately the vendor changed the cake. 
The following cases refer to samples of manure : — 
6. Mr. J. Smith, jun., of Pattiswick Hall, Braintree, Essex, 
sent on November 10, 1890, a sample of a material, 10 tons of which 
he had bought on Braintree Market as fish manure at 55s. per ton. 
The manure was stated to be " condemned fish from Billingsgate, 
treated with a little acid." The following analysis and report was 
returned on November 20, 1890 : — 
Moisture 1805\ 
Loss on heating 12-55 
Sulphate and oxides of iron, &c 41-06 - 100 00 
Sulphate of lime 7-89 
Insoluble silicious matter 20 - 45 ' 
Containing nitrogen 0 - 36 
Equal to ammonia ..... 0 44 
This refuse contains no phosphate of lime and only traces of ammonia. 
It is not fish manure at all, and is worthless. 
The following cases refer to samples of superphosphate of low 
quality : — 
7. Mr. H. Joxes, of Eaton] Bishop, sent on April 26, 1890, a 
sample of superphosphate costing 3/. 6s. per ton delivered at 
Hereford. On analysis the sample proved to contain only 21 33 
per cent, of soluble phosphate. 
8. Messrs. Clutton, agents for Sir C. R. Burrell, Bart., sent-ou 
May 6 a sample of superphosphate, price 3/. 5s. per ton in London. 
The sample contained 19 - 88 per cent, of soluble phosphate, and was 
reported on as an inferior sample in bad condition.
