The Monthly Magazine, Or, British Register for 1798 included an explanation by a reader of how the cut was carried out in his college days in a lengthy letter to the editor, signed by the pseudonym Ansonius. In his rambling letter, Ansonius noted that when he was at college, … if a man passed an old acquaintance wittingly, without recognizing him, he was said— ‘To cut him.’ Ansonius then went on to explain the performance of the cut and noted that for a time the term to spear was used instead of to cut. However, that term did not remain long in use, and this act was generally known as the cut ever after.

The covariance of X and Y is the expected value of the product of two random variables, X − E(X) and Y − E(Y). […] If two random variables tend to act like opposites, one is high when the other is low and vice versa, then the covariance will be negative. If two random variables tend to be high and low at the same time, then the covariance will be positive. In fact, the covariance measures the extent of a linear relationship between the two random variables.

In the figure 55 is shown a “wingless cricket,” of the subfamily Decticinœ of authors. This group contains many very queer looking creatures, and also some that occasionally increase in such numbers as to become pests. Our large “Mormon cricket,” the one shown in the illustration, is an example of the latter kind.
