Neatness and care in drawing geometrical figures- should be impressed upon the students;, the object c of such practice is to secure accuracy, which can only be attained by precision in practice. Take one easy problem, viz. to bisect a straight line. Here we have a diagram, and the directions : "...

The standard English unit for the measurement of work is the work done in raising one pound weight vertically one...
Page 451 - It is also contained in small quantities in galena (p. 210), and it can be extracted with profit from the lead prepared from this ore, even when the lead contains only two or three ounces of silver to the ton. The method thus adopted for the extraction of the silver depends upon the fact that the whole of the silver can be concentrated into a small portion of lead, by crystallization; metallic lead free from silver separates out in crystals, and a rich alloy is left. When this reaches the concentration...
