184 The Life and Work of John Ray, and Stirpium Britannicarum,' which, after the 'Historia' and the 'Methodus,' forms the third laurel in his botanical crown, being, as it was, the first systematic English Flora, and not only remaining for many years the pocket-companion of every British botanist, but acting also as the model for many similar works. It is worth notice that in the Preface to this work Ray, who never said what he did not earnestly believe, thanks God and congratulates his country on the establishment of religion, law, and liberty by the Revolution of 1688. In the following year, 1691, Ray issued, in an elaborated form, one of his earliest productions, 'The Wisdom of God manifested in the Works of the Creation,' which, as I have said, is considered by competent judges to entitle him to rank as a theologian with Paley and Butler.

This work contains much interesting geological speculation, based upon a large number of carefully observed facts, and was also very successful, reaching a second edition in the following year, and a third in 1713. In spite of increasing age and infirmity, at the urgent suggestion of his friends, and particularly of Dr. (afterwards Sir) Tancred Robinson, that he should undertake a Fauna Anglica and a History of Fossils, he did, at the age of 66, undertake a Synopsis of Quadrupeds and Serpents, which appeared in June, 1693, having been apparently completed in a year, and of which Dr. Pulteney says, "In this volume we see the first truly systematic arrangement of animals since the days of Aristotle." His classification is based upon the digits and the teeth, distinguishing the Solidungula, Bunii-
