Transcriber's Notes

Page 12: changed "guage" to "gauge" ( ... cotton-covered copper wire, say No. 20 gauge ...)

Page 35: changed "change" to "charge" ( ... losing at the same time its electrical charge ...)

Page 55: changed "guage" to "gauge" ( ... 1 foot of No. 41 gauge pure copper wire ...)

Page 64: changed "exaet" to "exact" ( ... of the exact diameter of the turned ends of the cores ...)

Page 73: moved comma "Rivetting, is" to "Rivetting is," (Rivetting, is perhaps, the best mode ...)

Page 81: added hyphen ( ... along the short length of wire to the right-hand binding-screw ...)

Page 83: changed "head" to "heads" ( ... the possible defects of electric bells may be classed under four heads: ...)

Page 92: changed "its" to "it" ( ... until it rests against the stop or studs.)

Page 102: changed "contract-breaker" to "contact-breaker" (When the contact-breaker is used, ...)

Page 103: changed "instead" to "Instead" (Instead of the armature and clapper ...)

Page 132: in the Morse code for "BRING THE", the code for "H" has been corrected from two dots to four dots.

Page 136: changed "eletro-magnet" to "electro-magnet" ( ... if the electro-magnet were energised ...)

Page 137: changed "idicator" to "indicator" (since the indicator falls forwards)

Page 146: changed "arrangment" to "arrangement" (the size and arrangement of the batteries and wires)

Page 146: added comma "nails," ( ... chance contact with nails, staples, metal pipes or other wires ...)

Page 179: changed "carboard" to "cardboard" ( ... for our purpose we will choose cardboard.)

Page 179: changed "Tanstickor" to "TÃndstickor" ( ... double it to the form of a TÃndstickor match-box, ...)

Page 185: suspected typo (unchanged) "Emmot" should perhaps be "Emmott" (... the electrical firms of Messrs. Blakey Emmot, ...)

Page 186: changed "LeclanchÈ" to "LeclanchÉ" ( ... polarizes much less quickly than the ordinary LeclanchÉ.)

Page 187: changed two instances of "AmpÉre" to "AmpÈre" in the index (AmpÈre, 55 / AmpÈre's law, 11)
