The first card (no. 28) shows the anatomy of an "automatic lighter" (actually it is a semi-automatic lighter).
On the back of the this card Wills explains how this lighter work:
When the spring knob is pressed the lid flies open, and the steel wheel A rotates. The “flint” is held against the wheel by a spring (not shown in the diagram), and the friction of the milled edge of the steel wheel against the “flint” sends a spark to the wick C and ignites it. The wick is fed from the small reservoir D, which is packed with cotton wool and supplied with petrol.
Old-fashioned phosphorus matches had many disadvantages. The ordinary white or yellow phosphorus used in them is a deadly poison responsible for many accidental deaths, while the workers who made the matches often suffered from phosphorus poisoning. A modified form of phosphorus know as red phosphorus was first used for making matches in Sweden about 1850. This is perfectly harmless substance, and the manufacture of Safety-Matches is therefore not dangerous. Modern matches are safe in another sense: the phosphorus required for lightning is on the box and not in the match-heads, which are therefore much less liable to catch fire accidentally.
