KEPOKT OF THE CHEMICAL COMMITTEE, 5 June, 1849. 



The Chemical Committee have considered the charges for the different 

 subjects of analysis, and have seen no reason for any material alteration in 

 the scale, which stands as follows : — 



No. 1. An opinion as to the genuineness of a manure in the market, 

 75. Qd. By this is meant such an opinion as could be formed by a scientific 

 person, by inspection, with a few simple confirmatoiy experiments. — [It will 

 protect from fraud, but is not calculated to assist in the choice of the best 

 specimens, where all are genuine : it will inform the applicant whether a 

 specimen of guano or oil-cake, for instance, be adulterated or not; but 

 will not touch the question of its relative value as a pure specimen. Such 

 an opinion will only apply to ordinary market articles, as guano, oil-cake, 

 superphosphate of lime, sulphate of ammonia, gypsum, common salt, &c.] 

 No. 2. Guano. A. determination of nitrogen (ammonia) and of the earthy 

 phosphates, &c., 1/. No. 3. Limestone. The proportion of lime, 7s. 6<i. ; 

 the proportion of magnesia, 10^. ; the proportion of lime and magnesia, 

 15s. This analysis is sufficient for many purposes ; but in most limestones 

 the phosphate and sulphate of lime, and maa:nesia, are present, though in 

 small proportions ; and inasmuch as it is impossible to say how much of 

 the effect may be due to other minute ingredients, it is recommended that 

 their quantity should always be determined. No. 4. Limestone, or marls, 

 includmg carbonate, phosphate, and sulphate of lime, and magnesia, with 

 sand and clay, \l. No. 5. Partial analysis of a soil, including sand, clay, 

 organic matter, and carbonate of lime, 1/. No. 6. Complete analysis of a 

 soil, 3/. No. 7. Letter asking advice, one topic, 7s. 6*^. On more than 

 one topic, 10s. No. 8. Oil-cake, or dung, or any animal products, nitrogen, 

 and phosphoric acid, 1/. Oil-cake, including nitrosjen, oil, and phosphoric 

 acid, 1/. 10s. They have also added a ninth subject, namely, No. 9. A 

 determination of the quantity of carbonate and sulphate of lime in any 

 specimen of water, 1/. 



They recommend a grant of 300/. for the ensuing year, to be apportioned 

 in the following manner : — A sum not exceeding 100/. for an account of 

 analyses of guano (a paper on which subject is nearly completed). 2. A 

 sum not exceeding 100/. tor an account of analyses of oil-cake and linseed, 

 with reference to the nutritive qualities of different specimens. 3. A sum 

 not exceeding 100/. for an account of analyses of chalk and marls used in 

 top-dressings. 



" The Committee further recommend that when Mi\ Way is applied to 

 for an analysis he shall inform the applicant the cost of such analysis, 

 together with the cost of carriage of any specimen sent up, and shall not be 

 authorized to make such analysis until the amount due shall be sent to him. 



" That a printed copy of this resolution be sent to every member apply- 

 ing for an analysis."
