tions of the apparatus or machinery employed in preparing the mate- 

 rial in any of the processes alluded to. Examples also of the varieties 

 of manufacture, selected with the view of their being presented to 

 native workmen as models for imitation, ought also, I conceive, to be 

 procured for this department ; in the higher and ornamental descrip- 

 tions of Pottery such specimens ought, of course, to be chosen as may 

 be distinguished for beauty of design, both in relation to form and em- 

 bellishment, so that the purest models may be presented for study, and 

 some perception of the truly chaste and beautiful infused, if possible, 

 into the native mind. I would only add on this subject, that the 

 specimens of Indian Pottery exhibited in the decorations of native 

 temples and palaces, display such an extent of knowledge in the simple 

 process of manufacture, and in the nature and methods of applying 

 colouring materials, as to encourage the belief, that were the standard 

 of taste corrected and refined, this improvement would be rapid and 

 important. A series of illustrations of our manufactures in Glass, 

 similar to that recommended for those in Pottery, might be expected 

 to call attention to a department of industry, for which the requisite 

 materials exist in abundance in these Provinces ; but which I believe 

 has hitherto been followed only to a most limited extent. 



10. Intimately associated with the preceding, as furnishing to the 



Porcelain painter or Glass stainer, the materials 

 thf TeTartoent of required for the completion of his designs, is the 

 Mineral Pigments department of Mineral Pigments. This however is 



by no means limited to manufactures, it extends also 

 to the arts, and to the more common applications of painting, for both 

 of which it furnishes some of the most important colours required. It 

 is only necessary at present to refer, as examples, to the chromates of 

 iron and lead, the various ores of cobalt and manganese, in Porcelain 

 painting, and different departments in glass manufacture; to the pure 

 and impure bi-sulphurets of mercury or vermillion and cinnabar ; to 

 the arseniates of sulphur, or red and yellow orpiment, in the arts ; and 

 to the sulphate, blue and green carbonates of copper, the colcothar or 

 oxide of iron, sulphate of zinc, in the more common varieties of paint- 

 ing. There is farther, a large class of colouring materials derived from 

 combinations of the foregoing, and others in various proportions, as 

 smalt, from the mixture of the ores of cobalt with silica and potassa,
