The Council have fixed the following rates of Charge for 

 Analyses to be made by the Consulting 1 - Chemist for Members of 

 the Society ; who, to avoid all unnecessary correspondence, are 

 particularly requested, in applying to him for analyses, to mention 

 the kind of analysis they require, and to quote its number as 

 specified in the subjoined schedule. The charge for analysis, 

 together with the carriage of specimens, must be paid to him by 

 the members at the time of application. 



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

 7s. 6d. By this is meant such an opinion as could be formed by a sci- 

 entific person, by inspection, with a few simple confirmatory experi- 

 ments. — [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 ordi- 

 nary market articles, as guano, oil-cake, superphosphate of lime, sul- 

 phate of ammonia, gypsum, common salt, &c] No. 2. Guano. A. de- 

 termination of nitrogen (ammonia) and of the earthy phosphates, &c, 

 1/. No. 3. Limestone. The proportion of lime, 7s. 6d.; the propor- 

 tion of magnesia, 10s. ; 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 magnesia, 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, including carbonate, phosphate, and sulphate 

 of lime, and magnesia, with sand and clay, 1Z. No. 5. Partial ana- 

 lysis of a soil, including sand, clay, organic matter, and carbonate of 

 lime, 1/. No. 6. Complete analysis of a soil, 3/. No. 7. Letter ask- 

 ing advice, one topic, 7s. 6d. On more than one topic, 10s. No. 8. 

 Oil-cake, or dung, or any animal products, nitrogen, and phosphoric 

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

 1L 10s. No. 9. A determination of the quantity of carbonate and 

 sulphate of lime in any specimen of water, 1/.
