A PORTABLE LITHOTOMY FRAME
498 A short description of the sensitised-sheep-cell agglutination test is hard to follow and will doubtless be revised in future
editions. Modern Views on the Secretion of Urine Cushny Memorial Lectures, edited by F. R. WINTON, M.D., D.se., professor of pharmacology, University College, London. London : J. & A. Churchill. 1956. Pp. 292. 30s. .
THIS book gives the substance of the ten Cushny lectures given at University College, London, in May of last year. All but two are by past or present members of the college, and the book is to that extent a posthumous Festschrift to a pioneer of renal physiology in this country. In his foreword, Professor Winton lays his finger on the essential contribution of Cushny to nephrology-he stated his views in such a way that they permitted, and indeed invited,

Much of presentday renal physiology stems from his famous monograph on The Secretion of Urine (1917, 1926), despite the fact that his denial of tubular secretion, and his affirmation of an ideal reabsorbate with the composition of normal protein-free plasma, are now entirely outdated. (Actually, one of the lectures is on the Process of Secretion, and several others imply the separate handling of urinary constituents.)
The subjects and lecturers were well chosen, and in addition to standard renal physiology (clearances, antidiuretic-hormone action, and the like) there are rather less usual lectures on the process of. secretion (L. E.

ONE of the difficulties of domiciliary obstetrics is to keep the patient in the required position. Though the left lateral position is preferable for the uncomplicated delivery and safer for general anaesthesia, the lithotomy position is the more convenient for pudendal-block anaesthesia and repair of the perineum. Hitherto there has not been any satisfactory portable contrivance (comparable to the lithotomy supports of the Chassar Moir labour-ward bed) for maintaining the labouring woman in this position. All too often the patient sinks into a pool of liquor in the bottom of the bed, while her attendants lean over her with aching backs. I therefore decided to design a support which could be easily transported in a car and would fit any sort of bed. many different sorts of beds
