This booklet is of interest as indicating a point of view and the tendencies of those who adopt it. The author is a zoöphilist vegetarian; he uses no scientific arguments in favor of his thesis, but is, especially as he warms up to his subject, abusive and intolerant to those that may disagree with his dietetic opinions. "Christian cannibals," "ghoulish clowns of science," are samples of some of his utterances. Like Marryat's boatswain, he begins with moderation, but becomes vituperative as his remarks progress. Vegetarianism is apparently just now being taken up with more vigor; its propaganda is more active than for some time past. Such little works as this are evidence of the fact, but they do not convey altogether favorable impressions of the temper and judicial mindedness of their writers.
