Publisher's Synopsis
Excerpt from Transactions, Vol. 35: 1885-86
Mr. Swan's interesting description of his portable electric lamp clearly showed the possibility of making a lamp - not unduly heavy, which would give out a light in excess of that usually Obtained - at a reasonable price, and at a cost for maintenance below that usually incurred in the ordinary oil lamps. Mr. Kendall's comprehensive paper on the Iron Ores of the English Secondary Rocks forms a valuable work of reference on this subject.
