About This Book

Comprehensive clinical manual detailing disorders of the nervous, genitourinary, ocular, and integumentary systems in domestic animals. It begins with principles of neural control and general symptomatology, classifying motor, sensory, and psychic disturbances and methods for localizing lesions. The text describes specific conditions such as seizures, paralysis, meningitis, intracranial hemorrhage, tumors, and toxicoses, and outlines diagnostic signs and pathological causes. Later sections address urine analysis and renal disease, urinary tract inflammation and calculi, and diseases of the eye, skin, and constitutional systems, combining pathological description with clinical signs, differential diagnosis, and practical guidance for examination and interpretation.

DOUBLE PUPIL.

Mayer notes a case of congenital double pupil in the horse, a bridge extending across the space from the upper to the lower border and cutting off the outer third of the opening. The present writer has seen a similar condition as the result of union of the corpus nigrum in severe iritis. Section of the bridge is possible, though rarely desirable, seeing that it opens a door to possible infection.
