Globular Lightning
Globular lightning, in the form of balls of fire, which move slowly along and then burst with a sudden explosion. This form is very rare, but must be admitted as a real phenomenon, though some of the accounts of it are greatly exaggerated. Similar phenomenon on a smaller scale have been produced (though usually accidentally) with electrical apparatus. (Thompson, Silvanus P.; Elementary Lessons in Electricity & Magnetism; The MacMillan Company, NY, 1899)

Sheet Lightning
Sheet lightning, in which whole surfaces are lit up at once, is probably only the reflexion on the clouds of a flash taking place at some other part of the sky. It is often seen on the horizon at night, reflected from a storm too far away to produce audible thunder, and is then known as "summer lightning". (Thompson, Silvanus P.; Elementary Lessons in Electricity & Magnetism; The MacMillan Company, NY, 1899)

Zig-Zag Lightning
The Zig-zag flash or Forked Lightning of ordinary occurrence. The zig-zag form is probably due either to the presence of solid particles in the air or to local electrification at certain points, making the crooked path the one of least resistance. (Thompson, Silvanus P.; Elementary Lessons in Electricity & Magnetism; The MacMillan Company, NY, 1899)
