The estimation of vitamin C in the urine has recently been undertaken on a fairly large scale on patients suffering from physical disturbances. Harris (1) and his co-workers investigated 74 hospital patients at Cambridge, and found that 62 (84%) excreted less than the minimum standard, or 13 mgrm. per day. Excluding 19 on special diets, 43 excreted less than 13 mgrm. per day, and the average excretion of 55 was 10 mgrm. per day.

The hippuric acid excretion test (after benzoate administration) has been used by previous workers, with the general result that it affords a reasonably accurate and satisfactory test for determination of parenchymatous hepatic damage and of various hepatic involvements. The test is also known to be indicative of hepatic disorder, even where no clear clinical signs of hepatic or renal derangements are observable. A series of 67 cases of mental disorder has been examined by the test, 45 of which belonged to the schizophrenic group; 18 of these were classed as catatonics. The average value of hippuric acid eliminated in the non-catatonic schizophrenic group, expressed in terms of benzoic acid, in 4 hours after administration of 6 grm. of sodium benzoate, was 3.4 grm. with an average deviation from the mean of ± 0.4 grm. This value agrees well with the values obtained by previous workers for normal cases having no hepatic damage. The average value of hippuric acid eliminated under the same conditions by catatonic patients was 2.2 grm. with an average deviation from the mean of ± 0.5 grm. All the catatonic patients studied, without exception, showed a diminished ability to excrete hippuric acid at a normal rate. It is inferred that a metabolic disturbance of the liver affecting benzoic acid detoxication may be a characteristic feature of catatonic patients.

Work on benzoic acid detoxication in catatonic patients before and after various shock treatments for schizophrenia is in progress.

Originally the conception of disturbances of the cerebral circulation was closely associated with that of gross arterial and venous disease, and it was in these conditions that the typical pictures of hæmorrhages, hæmorrhagic and anæmic infarctions (softenings), scars and cysts as their sequelæ were first studied. These sequelæ are in all essentials the same in the brain as in other organs with similar vascular arrangements, such as the kidney and the spleen, with the exception of some peculiarities due to special structure or special staining reactions. Recent ischæmic necrosis of the grey matter appears in Nissl-stained specimens as areas of pallor, and examination under high magnification often reveals a special type of ganglion-cell change called ischæmic by Spielmeyer (16), which so far has maintained its reputation as being highly specific. A further peculiarity is provided by the activity of the glia in all processes of breakdown and repair. In vascular disease especially, a type of mobile glial-mesodermal activity is met with (Spielmeyer (16)), that is to say, the glia acts jointly with the mesenchymal tissue in the production of scavenger-cells and of fibres.

Despite the modifications introduced at Cardiff (1, 2, 3), somnifaine prolonged narcosis remains a dangerous procedure (4, 5), and we had hitherto thought that the method could only be made perfectly safe by reducing the dose below a level which is therapeutically valuable. Witt and Cheavens (6), followed by Day (7), have, however, used a medinal-luminal mixture with apparent safety and with good results, and we have followed their technique in 60 cases. A mixture containing medinal 5 gr. and luminal 1 gr. in each drachm is used. The first dose is 2 drm., which is repeated 4-hourly till sleep occurs; thereafter 1 drm. is given as required. The usual methods of nursing are adopted (3, 4), and Day claimed that narcosis could be continued for as long as 78 days with a gain in weight of from 5 to 30 lb.

When, a few months ago, your Association honoured me with its invitation, I undertook the task of presenting to you the results of the first 100 cases treated in the Clinic in Vienna. I intended to draw from the individual reactions and the effect of the therapy some conclusions as to its justification. I could also have brought forward conclusions drawn from the records of cases whose treatment has been terminated for a long time and who have remained under continuous observation. These results would have been of some value inasmuch as these would have referred to the cases which I myself treated individually, and in which treatment had been individualized by employing various types of shock.

The immature psyche of the child is at least as easily upset by both organic and psychological factors as is that of the adult. The slightest fever or digestive upset may, in a child, lead to bad temper, lack of appetite and sleeplessness. In spite, however, of the ease with which minor psychological disorders are brought about, the severe mental disturbances constituting the psychoses are very infrequently met with. Those to be described occur in the early years of life. Some of them resemble serious behaviour and personality disorders; some would seem to be of organic ætiology. Common to all are regressive changes leading especially to loss of recent attainments, and to some disorganization of the personality following a hitherto normal development.

Whilst it is an undisputed fact that under certain clinical and experimental conditions various antibodies (antitoxins, agglutinins, bacterio- and hæmolysins, complement-fixing antibodies) can be demonstrated in the cerebrospinal fluid, there is a divergency of opinion about their origin. Whereas some authors (Dujardin and Dumont, Ramon, Descombey and Bilal, Neufeld and Szyle, Nélis) ascribe their presence in the cerebro-spinal fluid to their passage from the blood through a damaged blood-cerebro-spinal fluid barrier, other investigators (Mutermilch, liiert, Grabow and Plaut, Friedemann and Elkeles) believe that the central nervous system or its membranes are able to produce antibodies on their own upon contact with an antigen. In the case of the Wassermann antibody in the cerebro-spinal fluid the question of its origin is of particular interest, because of the occasional occurrence of cases which show a positive Wassermann reaction in the cerebro-spinal fluid and a negative or weaker reaction in the blood. This divergence between blood and cerebro-spinal fluid is often quoted as an example of the independence of the cerebro-spinal fluid antibody.

It is now a little over twelve months since the investigation and treatment of chronic infective disease was undertaken at this hospital, made possible by the erection of a treatment centre and the appointment of an ear, nose and throat surgeon. From what I have seen of the results obtained during the period under review I am convinced of its therapeutic value, not only in recent cases of psychosis where other forms of treatment have failed, but also in chronic cases, which my clinical experience would have pointed to as hopeless, has amelioration taken place.

Pace Mr. Punch, we know that there are plenty of takers, and anyone who uses convulsion therapy soon becomes convinced that much good is achieved in one way or another. Moreover, it has become evident that the treatment is not applicable to schizophrenia only; some striking results are seen in depressive states and in atypical paranoid and obsessional cases. This matter is dealt with at length in Dr. Cook's paper. These results, together with the comparative ease of application of the treatment, suggest that it will inevitably be tried out on a very large scale indeed.

Agenesis of the corpus callosum is not as rare as might be expected and over a hundred cases are on record. It is, however, remarkable for the diversity of the clinical signs that are associated with it, and no doubt these are dependent on other anomalies of the brain, some of which apparently always accompany this condition.

The term “dysentery” in mental hospitals may be regarded as applicable to a clinical entity characterized by symptoms of abdominal pain, rise of temperature and passage of blood and mucus. The causative organisms are various, but that occurring most frequently and persistently is the Bacillus dysenteriæ of Flexner. This paper deals exclusively with this type of asylum dysentery.
