The captive bolt is placed against the skull of the animal, and penetrates to cause tissue destruction in the brain, incapacitating the animal so that the procedure may take place. Electricity is used mostly to
Horner's method a single named contribution to "The Gentleman's Mathematical Companion", an answer to a problem. It is questionable to what extent it was De Morgan's advocacy of Horner's priority in discovery that led to "Horner's method" being so called in textbooks, but it is true that those suggesting this tend themselves to know of Horner largely through intermediaries, of whom De Morgan made himself a prime example. However, this method "qua" method was known long before Horner. In reverse chronological order, Horner's method was already known to: However, this observation on its own masks significant differences in conception and also, as
