The authors distinguish between perineal hernia and flexure of the rectum. They describe in detail an operative procedure to treat these conditions using a transplanted superficial gluteal muscle to reinforce the ischio rectal fossa.

The Authors consider the following problems associated with cervical salivary cysts: incidence, distribution, diagnosis, cause, pathology, treatment and results of treatment. They present detailed comments on the prospects of success using a line of treatment modified from that originally &&bed by Berge (1938) and more recently described by Kealy (1964). I N T R O D U C T I O NALTHOUGH salivary cysts are the commonest conditions of salivary glands that veterinary surgeons are called upon to treat, the incidence of the condition is relatively low; only one case in approximately 4000 patients that attend the Small Animal Clinic at the University of Edinburgh Veterinary School suffers from the complaint; none the less the condition is important because of its intractable nature.Study of the problem is difficult, not only because cases are relatively scarce, but also because the terminology used in most anatomy text-books is confusing and because their descriptions of the salivary glands in the dog are inaccurate. The pathology of the condition is indefinite and none of the treatments currently described give consistently satisfactory results. Recent publications on this subject by Berge and Westhues (1961), Spreull et al. (1964), Kealy (1964), Hulland and Archibald (1964) and Spreull (1965) still leave many interesting and important aspects of this condition unsolved. This publication establishes some of these special problems and contributes to their solution.

Abstract— The author reviews the literature on otitis media in the dog. Based on a study of 100 normal dogs, the structural variations and appearance of the tympanic membrane are described and compared with the changes that were observed in 100 otitic ears, fifty of which were recent cases and fifty longstanding cases which were treated surgically. The incidence of otitis media is given in the two otitic groups studied. The equipment and techniques used in examination, the criteria for diagnosis, the pathology and the treatment are described and discussed.

Abstract— —The authors describe briefly the anatomy and histology of the normal ear and the histopathological changes associated with otitis. The bacteria and fungi associated with infections of the ear are discussed. The incidence and results of treatment of otitis externa in out‐patient and hospitalised cases are reported and the techniques and results of surgical procedures for conditions of the ear are detailed.

Abstract— The findings of two recent surveys of external ear disease in dogs are summarized, with particular reference to the aetiology of the condition and the results obtained with some methods of treatment. The commonest predisposing factors to otitis were clinical skin disease and ectoparasitic infestation, in that order. The appearance of the discharge in affected ears appeared to be related to the tissue changes present and to the nature of the infectious agents. Antibiotic sensitivity tests were of value and most cases responded promptly to appropriate medical treatment. In the more chronic cases, which were usually associated with considerable changes of the epithelium, treatment was often prolonged and about one in ten showed no improvement. Where medical treatment failed, thorough cleaning of the ear, under general anesthesia, was of value. A surgical technique is described which has been used with success in a number of cases and which, in certain circumstances, appears to have some advantage over the methods described by Zepp and Singh and Rao.
