Methods and Theory of Physiological Histology. . By Gustav Mann. M. D., C.M., Edin., B.Sc. Oxon., Senior Demonstrator of Physiology in the University of Oxford. Oxford; Clarendon Press, 1902.

IN the world of physiology and pathology the name of Dr Gustav Mann has for a good many years been well known as that of a laborious worker in connection with micro-anatomy and micro-physiology, and there can be no doubt that the present work will add greatly to the reputation that he had already gained. It is not, like some other books with a similar title, a mere compendium of formula: and staining prescriptions, but a philosophical treatise in which an earnest attempt is made to unravel and explain the physics and the chemistry of the methods employed in the study of the ultimate structure and composition of living cells and their derivatives. Naturally, among these methods fixation and staining come in for a very large share of attention, but such subjects as bleaching, isolating, decalcifying, injecting blood and lymph vessels, methods of obtaining sections, and microtomes, are also fully dealt with. Although we have said that the work is no mere collection of formula:, it contains a description of all the methods of staining, fixing, etc., which have hitherto been published, accompanied by much valuable advice as to the selection of methods and reagents for particular purposes in histological work. The work, in short, is one that everyone engaged in histological work, whether normal or pathological, will be glad to have constantly at his hand.

Leitfaden fUr Fleischbeschauer. Von Dr R. Ostertag, Professor an der Tierarztlichen Hochschule zu Berlin. Berlin; Richard Schoetz, 1903.

vVandtafeln fiir Fleischbeschau. By tbe same Author and Publisher.

THE first of these is a small handbook of 205 pages, designed to meet the requirements of the lay or non-veterinary meat inspectors, who, under the laws relating to the subject, have a definite and restricted role assigned to them in Germany. Such lay inspectors have to pass an examination before a Board of veterinary surgeons, and in order to qualify themselves for that examination they have to attend a public slaughter-house for not less tban four weeks, and during that period receive theoretical and practical instruction in the inspection of meat.

Licensed lay inspectors have their duties limited as follows; Inspection before slaughter can only be carried out by them on ;-

I. Perfectly healthy cattle, calves, sheep, goats, swine, or dpgs. 2. Animals which exhibit only the symptoms of unimportant diseases

(without serious constitutional disturbance). 3. Animals which not more than twelve hours previously have ex­

perienced a fracture of a bone, or other similar injury. After slaughter they can only examine or give an opinion regarding ;­

I. Perfectly healthy animals. 2. Slight and easily recognisable abnormalities. 3. Carcases or organs surrendered by the owner as unfit for fOOd.

CLINICAL ARTICLES. SI

With this explanation of what is expected of the lay meat inspector, we need only add that Professor Ostertag's latest work is certain to prove of great value to the class for which it is intended. It contains a large number of excellent illustrations.

The wall-diagrams by the same author are six in number. The first contains figures of the ox, calf, sheep, and pig, with lines indicating the customary methods of dividing the carcase; the s,econd is devoted to the teeth of the ox, sheep, and pig, as indicative of age; and the remainina four are intended to serve as guides to the position of the various groups of lymphatic glands in the same animals. The cost of the series is 20 mark (£1). Both teachers and students will find them useful.

OBSTRUCTION OF THE COLON DUE TO A CALCULUS.

By G. P. MALE, M.R.C.V.S., House Surgeon, Royal Veterinary College, London.

AN aged cab mare was admitted to the infirmary at 7 A.M., 2nd March, showing symptoms of abdominal pain. .

For two days previously no fceces had been passed, and on the preceding evening indications of pain had first been noticed.

There was no history of a previous attack. After admission she showed dull pain, lying down at intervals;

pulse, 60 and full ; temperature, 101° F.; respirations, 16; in fact, all the symptoms of impaction of the colon.

On exploration, the rectum was found to be dry and ballooned, and an accumulation of fceces was found in the double colon.

A ball containing carbonate of ammonia and nux vomica was administered, followed by a hypodermic injection of eserine sulphate It grs., and pilocarpine It grs., and frequent enemata.

At 3 P.M. a drench containing 2 ounces of oil of turpentine and It ounces of aromatic spirits of ammonia in a pint of linseed oil was admin istered.

At 9 P.M., the mare being still in pain, a similar injection of eserine and pilocarpine was given to excite peristalsis.

3rd March. Pain still manifested by turning the head to the flank and lying down. The temperature was now 103° F., respirations, 30, and the mucous membranes much injected.

Eserine and pilocarpine It grs. were again administered, but, having no effect, a 3iv. physic ball was given.

4th March. Still no action of the bowels. The mare was now weaker; the temperature 10f F., pulse 80, fluttering and irregular.

Ammonium carbonate 3ij. and ginger 3j. were exhibited at intervals during the whole of the three days. .

Towards evening a small quantity of liquid fceces were voided, the mare straining somewhat.

5th, 6th, and 7th March. Pain was absent, the bowels acted
