CURTIS'S NEW WORKS ON THE EAR.

A TREATISE ON THE

PHYSIOLOGY AND DISEASES OF THE EAR; With the most approved Modes of Treatment; accompanied with a Plate of Acoustic Instruments, descriptive of the French, German, and Spanish Artificial Ears; also, an Improved Hearing Trumpet.

BY JOHN HARRISON CURTIS, Esq.

Aurist to His Majesty, and their Royal Highnesses the Duke and Duchess of Gloucester, Surgeon to the Royal Dispensary for Diseases of the Ear, Fellow of the Medical Society of London, &c. &c. Fourth Edition, revised. Price 78. 6d.

The present Edition is intended to convey a plain, yet scientific knowledge of the important and interesting subject it discusses; it contains much new information on Otitis, Otorrhea, Nervous Deafness, and Cases of Deaf and Dumb, and particularly points out the serious consequences resulting from continued neglect and maltreatment of these affections. "It is certain, that many cases of deafness are susceptible of relief by judicious treatment. Perhaps the disposition now prevalent to seek for the cause of many local diseases in disorders of remote parts of the system, especially in the gastric organs, has led to the greatest improvement in the treatment of this as well as in many analogous affections. This indication is well followed by Mr. Curtis in all cases of deafness: excepting those of an organic nature, expressly local, his attention is directed to the constitution; and many cases of what are vaguely termed nervous deafness, of several years' standing, have been perfectly relieved. He has applied the principles above inculcated in an active and judicious manner, and the results of his experience appear to have been particularly favourable.”—–London Medical and Physical Journal.

"The number of editions through which Mr. Curtis's work has passed, is a sufficient proof of its value. We perceive he has enriched the present edition with those facts and observations connected with his subject which have recently been published in this country, and on the Continent. The cases which illustrate the work are instructive."-London Medical Repository. "Mr. Curtis, whose perseverance commands our applause, has published a New Edition of his Treatise on the Physiology and Diseases of the Ear. It had been determined that Diseases of the Ear were incurable, but Mr. Curtis has published a Series of Cases, sufficient to prove this error, and we congratulate the public on his success, as no diseases are more afflicting than those of this important organ."-Monthly Magazine.

"This work concludes with a detail of the most successful methods of Treatment, as exemplified in the cases of about sixty persons, who have been either partially or entirely recovered from that distressing state of distance and seclusion which the loss of hearing had occasioned. To those who are suffering under the painful privation to which his pages refer, we doubt not Mr. Curtis's Work will prove particularly acceptable."-New Monthly Magazine.

CASES ILLUSTRATIVE OF

THE TREATMENT OF DISEASES OF THE EAR, Both Local and Constitutional, Price 3s. 6d.

"The cases detailed by Mr. Curtis are fifty-eight in number, and the Treatment appears to be judicious, simple, and successful.”—Medico-Chirurgical Review.

"The Profession, we conceive, are indebted to Mr. Curtis, for the persevering spirit with which he cultivates the study of those diseases affecting the organ of hearing, which, from their obscurity and intricacy, can only be properly treated by a person entirely devoted to the subject."-London Medical and Physical Journal.

PROSPECTUS.

IN this Work, it is intended to give Coloured Plates of Birds,

accompanied by Descriptions, including their Generic and Specific Characters, references to the best figures of those already published, and occasional remarks on the nature, habits, and comparative anatomy of the species. The illustration of new groups and new species will be first attended to; next, such subjects will be given as have been described but not figured; afterwards, those which have been incorrectly represented, or where the variation in plumage, arising from age, sex, or season, has not been particularized; and lastly, in order to render the Work complete, all the species which have already been described or figured.

Since the commencement of the last century, great advances have been made in every branch of Natural History, both in Britain and upon the Continent. In Ornithology, however, the improvement has not been so rapid in this country, as in some other departments of Zoology. On the Continent that science

has had the advantage of a more general cultivation, the advocates in its favour having united their endeavours at an earlier period to promote its interests. The Ornithologists of Great Britain at last feel the necessity of co-operation, and are anxious to rescue this pursuit from the imputation of neglect. Hitherto we have suffered our activity to expire in wishing, rather than in attempting to accomplish; our efforts have been single; and while we have individually laboured in a science which ought to have been pursued in common, our continental neighbours have reaped the honour of our discoveries, and the distinction of making known to science a multitude of new Genera and Species, many of them from our own collections, and which ought long since to have been described by ourselves.

Another powerful reason why this department of Zoology has not advanced equally with other branches of the science, arises from the deficiency as well of elementary, as of more general and extensive works on the subject. The great expence attending the acquisition of an Ornithological Library, and the unlimited number of miscellaneous publications which must now be consulted for a knowledge of what has been effected in Ornithology, increase the difficulties of the student in his endeavours to keep pace with the present advanced state of the science. We have, in fact, no elementary work on Ornithology; and passing over the older writers, as containing comparatively few species, we may observe that the only British Works which pretend to give a general system of Ornithology, are, Dr Shaw's Zoology, still incomplete, and the General History of Birds by Dr Latham. The disadvantages arising from the limited number of Plates in the above-named works, so indispensable to this branch of Natural History, and the inferior execution of those which are given, must be generally acknowledged. The descriptions also are frequently so short, as to preclude the possibility of making out the Species; and in consequence of the Genera of the older systems being retained without any subdivision, the necessity of which is now so universally admitted, and these in some instances containing many hundred Species, the investigation of an individual is rendered an occupation at all times of considerable, and sometimes of ineffectual, labour.

With the view, therefore, of removing some at least of the inconveniences which at present attend the study of Ornithology in this country, and of making known the numberless new Species which are daily discovered, and are uselessly crowding both our public and private collections, the authors have commenced the following Work. In this undertaking they have been promised the most effective assistance. The rich collections of the British Museum, of the University of Edinburgh, and of the Linnean Society of London, that of the East India Company, together with the greater part of the best private collections in the country, have, through the liberality of their respective representatives, been thrown open to them; and they have obtained in addition, the scientific assistance of the distinguished Naturalists who superintend these collections. From the important cooperation of which they are thus assured, the authors are sanguine that the Work will be regarded as a national undertaking; and to render it worthy of such a character, no exertions will be spared on their part.

The drawings and engravings will be made by the authors themselves, or under their immediate inspection. They will be taken from living specimens wherever such can be obtained; and particular attention will be directed to the natural position and characters of each subject. Illustrations of the Generic distinctions and peculiarities of structure will be given either on the same Plates with the Birds, or on Supplementary Plates.

The Work will be published in Quarterly Parts, Royal 4to; each Part containing from fifteen to twenty Plates, on which will be figured from twenty to thirty Species. The price of each Part will be L.1, 11s. 6d.

A few copies will be printed on large paper, price L.2, 12s. 6d.
