G4 CHEMICAL DEPARTMENT. 



3. Quantitative determination of any one ingredient of a Soil, 



7s. 6d. 



4. Complete analysis of Saline Manures and other substances, 



such as Gypsum, Nitrates of Soda and Potash, Ammoniacal 

 Salts, Guano, Oil-cake, Bone-dust, Eape-dust, Superphos- 

 phate of Lime, L.l. 



5. Testing the above substances for adulterations — for each sample, 



5s. 



This exanination is generally sufficient to determine 



whether or not any of these substances are grossly 



adulterated, but it gives no idea of the comparative 



value of different Samples, where all are genuine. 



G. Determination of the percentage of Phosphates and Ammonia 



in a Guano, 10s. 



7. Determining the Quality of Soluble and Insoluble Phosphates 



in a Superphosphate, 10s. 



This and the proceeding determination generally suffice 

 to show whether the sample is of fair quality, and 

 corresponds with the analysis by which it was sold, 

 but not to fix its exact commercial value. 



8. Complete analysis of Limestone, Marl, Shell-sand, &c, L.l. 



9. Examining any of the above substances for the quantity of 



Lime, and ascertaining in the same the presence of Mag- 

 nesia and Alumina, 7s. 6d. 



Ascertaining the proportion of these, 2s. 6d. additional 

 for each substance. 



10. Complete analysis of the Ash of any Plant, L.3. 



1 1. Complete analysis of a Water, L.2. 



12. Determination of the Amount of Salts in Solution, and of the 



Lime thrown down by boiling in any water, 10s. 



13. Analysis of Tile or Fire Clay, L.l, 10s. 



14 Complete analysis of Eoots, Grains, and other Vegetable Pro- 

 ducts, L.l. 



15. Examining products of Vegetation, or of the Dairy, such as 



Nutritive Matters in Wheat, or other grain — quantity of 

 Butter or Cheese in Milk — 5s. for each ingredient. 



16. Determination of the quantity of Nitrogen in any substance, 



7s. 6d. 



17. Answers to letters asking advice on subjects within the depart- 



ment of the chemist, 5s. 

 The charges for other Analyses not specified in the list will be 

 settled by the Committee of Management, with reference to the 

 amount of work which they involve, and on a scale similar to the 

 above.
