XIV. — Quarterly Reports of the Chemical Committee. 
June 1884. 
De. Voelcker reported the following: cases : — 
1. Mr. P. M'Gregor, of Crowton Hall, near Northwicb, bought 
some dissolved bones at 8/. 55. per ton delivered, warranted 
made entirely of pure bones. Doubting the genuineness of 
them, he sent a sample on March 13th, which showed the fol- 
lowing analysis : — 
Moisture 14" 41 
*Organic matter 9 • 61 
Monobasic phosphate of lime 15*40 
Equal to tribasic phosphate of lime (24- 11) 
Insoluble phosphates 6-81 
Sulphate of lime, &c 47 ' 01 
Insoluble siliceous matter G"76 
100-00 
* Containing nitrogen "63 
Equal to ammonia '79 
This is not made entirely of pure bones, but is an ordinary 
superphosphate, containing about 10 per cent, of bones. Such a 
manure can in most places be bought at 5Z. IO5. to 6/. a ton. 
jVo farther information was given by the purchaser in reply 
to enquiries. 
2. Mr. W. Pering Paige, of Old Park, Waltham Cross, sent, 
on March 7th, a sample of London soot and sewage manure, 
of which he had purchased 2 tons at 40s. per ton, from the 
New Carbolic Sanitary Company (Limited). Works, Hackney 
Downs Railway Station (established 1873) ; W. Adams, Joint 
Manager. 
A circular sent to Mr. Paige gave, in addition to testimonials,
