Such is a brief outline of the history up to the present period of the establishment known as the Tower Menagerie. Of the animals contained in it during the summer of 1828, and of two others which had then recently died, the succeeding pages offer delineations, descriptions, and anecdotes. Among so numerous a collection of inhabitants, of such dissimilar habits, and brought together into one spot from such distant and various climes, some changes have almost necessarily taken place even while our work has been passing through the press; yet so excellent is the management of Mr. Cops, especially as regards cleanliness, that essential security of animal health, that not a single death has occurred from disease, and one only from an accidental cause: the secretary bird, having incautiously introduced its long neck into the den of the hyæna, was deprived of it and of its head at one bite. Other removals are owing to the spirit of commerce. The Cape lion, the chetahs, the Thibet bear, and the deep-blue macaw, have passed into foreign hands, and are now on the continent of Europe. Two of the wolves and one of the Javanese civets have been transferred to the Zoological Society; and the white antelope has also exchanged its habitation in the Tower for the delightful Garden created by that Society in the Regent’s Park. With the exceptions which have just been enumerated the whole of the animals which are here figured and described are actually living in the Tower Menagerie. Their continuance there affords a test of the fidelity of our work which could not be applied to any production on zoology that has yet appeared in this country, nor, to an equal extent, in any other. As a visit to the Menagerie will enable the reader at once to compare our representations and descriptions with their living prototypes, the imperative necessity of scrupulous accuracy has been deeply impressed throughout the whole undertaking on the minds of those who have been engaged in its completion. In this, it is trusted, they have fully succeeded. To explain the share which each has taken in the work, and to record a debt of gratitude to those kind friends who have assisted in it, is the pleasing duty which it now remains to fulfil. The whole of the drawings are from the pencil of MR. WILLIAM HARVEY, who, in seizing faithful and characteristic portraits of animals in restless and almost incessant motion, has succeeded in overcoming difficulties which can only be appreciated by those who have attempted similar delineations. In the portraits he has strictly confined himself to the chastity of truth; but in the vignettes, which have always some reference to the subject of the article which they conclude, he has occasionally held himself at liberty to give full scope to his imagination.
