What reading level is Semi Scientific Lectures book?
To quickly assess the difficulty of the text, read a short excerpt:
Of course, elec- tricity has long been used to produce single lights of great intensity, but these were expensive, and required regulators, &c. , of great complexity ; a pro- cess has now been discovered of subdividing the lights into any required number, and of different degrees of intensity, and these can be lighted and extinguished separately or simultaneously. It is possible cheaply to generate the current by a magneto-electric machine, and lay on the wires to the lamps, just as gas is now ...laid on. The burner consists of two pencils of carbon, placed side by side and separated by a bar of kaolin, or Chinese clay. When the current passes, these candles are slowly consumed, the kaolin burning at exactly the same rate. For small lights the carbon pencils may be dispensed with, and only kaolin used.
We have all suffered more or less annoyance and loss from our iron and steel possessions rusting and 207 becoming useless. A process has lately been dis- covered by Professor Barff for preserving iron from corrosion.
