A Manual of Blow-Pipe Analysis, and Determinative Mineralogy (Classic Reprint)

Excerpt from A Manual of Blow-Pipe Analysis, and Determinative Mineralogy IN preparing this little Manual, it has been my principal care to adapt it to the use of the beginner. The use of the blow-pipe, though elaborately studied and extensively written on by some of the first chemists and mineralogists of the preceding and the present century, has not yet been duly appreciated. This neglect is, perhaps, owing to the rapid advancement of chemi cal analysis in the humid way, which furnishes, on'the whole, more reliable results, and allows of an easy quantitative deter mination of the various constituents of a body. But it was over looked that this mode of analysis absorbs much more time, and requires the use oi' an extensive set of apparatus, whereas an examination before the blow-pipe is sooner performed; requiring scarcely as many hours as an examination ia' the humid way requires days, and that with the aid only of a few reagents and instruments of' small size. It is for this reason that a knowl edge of blow-pipe Operations is less valuable for the Chemist by profession than for the mining-engineer, the Mineralogist, and the Geologist. A small portable box will hold all the necessary reagents and instruments, so that he may carry them with him on his expeditions and travels, and examine on the Spot the minerals which he meets with on his explorations; an advan tage which ought, truly, not to be overlooked.
