The following anecdote, as related by Ray, will prove how necessary it is for all classes of men to be in some measure acquainted with botany: the counsellor who would be a judge, the student who would be a pleader, the juryman who would give an honest verdict, and the defendant who would gain his cause, will, in this instance, see the importance of botanical information.

"Baal, who was a gardener at Brentford, in Middlesex, having cultivated a remarkable fine cabbage, sold a large quantity of the seeds to several gardeners about the

suburbs of London. They committed them to the ground after the usual manner; but instead of the sort Baal had made them believe would spring up, they proved to be chiefly the brassica longifolia, instead of the florida. His incensed customers, in a body, instantly commenced, in Westminster Hall, a prosecution against him. The unfortunate man being unable to prove his innocence before the judges, the Court found him guilty of fraud; and he was condemned, not only to restore the price given for the seeds, but was likewise obliged to pay each gardener for the loss of time, and for the ground that had been uselessly occupied. His character and circumstances were consequently ruined; which impaired his health, and caused him to pay an untimely debt to nature. Had the judges been at all apprised of the sexual hypothesis, or had this honest man known, from careful observation, the use of the farina in rendering the pistillum productive, Baal would not have been found guilty of a crime, but the accident would have been attributed to the true cause, the fortuitous impregnation of the brassica florida by the farina of the brassica longifolia growing in the neighbourhood."
