When an analysis is to be made we proceed as usual, making the mixture in a warm mortar, only substituting the alkalized lime for oxide of copper; the accidental presence of a little moisture, after the weight of material for ana- lysis is accurately known, is of no consequence in this case. Having introduced the mixture, it is better loosely to plug the aperture of the retort with a few fibres of asbestus (which has been ignited just before) to prevent any mechanical trans- port of the mixture into the apparatus through which the gases are passed ; on applying heat to the combustion-tube in the ordinary way, and with the usual precautions, the substance is decomposed, and the whole of the nitrogen escapes as ammonia. The drying tube and potash apparatus are dispensed with, and the Fig. Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Todd, Robert Bentley, 1809-1860.
