ANOTHER ACTIVE CONSTITUENT OF ERGOT

,of the title pages, and is accompanied by explanatory and extremely interesting descriptions. In an .attractively modest preface the difficulties inherent in compiling a seventeenth century scientific bibliography are confessed, and the method which the modern bibliographer must adopt to obtain a result that satisfies his conscience and ideals is revealed to the reader. As the author remarks, "bibliography is indeed an all-absorbing occupation, but its devotee is frequently face to face with those who fail to under.stand the source of his enjoyment." This fine work, like the splendid " Bibliotheca Osleriana " (1929), must earn the sincere gratitude of those interested in ,the bibliography of medical science to the Oxford University Press.

Moir demonstrates that while both ergotoxine and ergotamine are active in stimulating contractions of the puerperal uterus, they are comparatively slow in taking effect, requiring 15 to 45 minutes after intramuscular injection, and 35 to 40 minutes or longer when given by mouth. Furthermore, their action when given orally is erratic. On the other hand, the administration by mouth of different samples of the B.P. 1914 Ext. ergotæ liq. in 2-drachm doses and of ANOTHER ACTIVE CONSTITUENT OF ERGOT Ext. ergotae in grs. 10 doses, results within a the A REMARKABLE paper by Dr. Chassar Moir, from few minutes in marked activity of the puerperal the obstetric unit of University College Hospital, the tone of which is also increased to an uterus, that is a there reasonable - concludes with the statement much extent greater than that seen with any other ,certainty that the characteristic action of ergot known oxytocic drug.

ANOTHER CLINIC FOR

THE " NERVOUS

speakers suggested that the action of chloroform, used in such a way, was largely psychological. Mr. Eardley Holland is able to achieve a similar happy result during the first stage of labour by reassurance, persuasion, and grs. 40 of chloral; and he deprecates the prolonged use of chloroform, even in such small dosage. Most speakers, however, seemed to think the capsules harmless enough, though some feared to place a drug as dangerous as chloroform in the hands of the midwife. Dr. Fairbairn, president of the Central Midwives Board, expressed interest in the device, and the opinion of the Section of Anaesthetics of the Royal Society of Medicine is being enlisted on the question whether midwives, after preliminary training, could safely be trusted with the capsules. ____

ANOTHER CLINIC FOR THE "NERVOUS" CHILD

THE movement towards the rational treatment of the so-called " nervous " or difficult child has been gaining ground through the pioneer work of a variety of organisations throughout the country. In London alone we have one under the auspices of the Child Guidance Council of Great Britain, the East London Child Guidance Clinic of the Jewish Health Organisation, a special department at the Institute of Medical Psychology, and the National Institute of Child Psychology; while Guy’s Hospital, the Children’s

Hospital, Great Ormond-street, University College Hospital, and Maudsley Hospital each have departments devoted to this work. The two first mentioned, and those in Birmingham and Liverpool, are planned on the American system of a clearly defined unit of psychiatrist, psychologist, and social worker who deal with the cases in close collaboration. The others are mostly equipped with the same basic staff, but the unit is closely organised and is related to the hospital to which each is attached. The West End Hospital for Nervous Diseases now proposes to establish a similar unit in the autumn, to which members of the hospital staff will be able to refer cases for special treatment, though cases will also be accepted from other sources. This will mean that not only will those " nervous " and difficult children be seen who have been diagnosed as free from organic disease, but that such organically afflicted children as have behaviour sequelae will be considered for psychological assessment (intelligence estimation, and so forth), and perhaps for treatment too. Observation beds will be available. This venture is of interestin that, for the first time, a hospital for organic nervous diseases is considering the more psychological aspects of child disorders on modern lines. Clinics that are not directly associated with hospitals tend to attract a large number of cases of the " behaviour " type, largely from the schools. The cases are chosen in consequence of the teachers’ attitude and the demands of school life, its curriculum and its discipline. Such clinics may fail to attract the attention of medical practitioners, or may not win their confidence because of the fear of entanglements with new theories away from the beaten track of medical tradition. It is important that such fears should be dispelled, but this will be only a gradual process. Meanwhile, the advantage of the West End Hospital clinic may lie in the fact that most doctors have, through tradition, associated disorders of behaviour and emotion with the action of the nervous system in the widest sense, despite the fact that disturbances in other systems are not without their psychological implications. It is, moreover, an admission that while careful differential diagnosis of nervous disorder

lines, psychological and perhaps sociological.

The

fact that London is now being rapidly provided with a variety of children’s clinics, bearing a basic resemblance to each other in the recognition of the need for medical, psychological, and sociological investigation, is satisfactory ; and since each is related to different hospitals and different forms of psychological or psychiatric organisation, their study of behaviour and emotional disorders in children will soon be approached from many fresh angles. A GROWTH-PROMOTING FACTOR

paper presented to the Biochemical Society June 11th, Mr. L. W. Mapson, of Cambridge, stated1 that fresh ox liver has been shown to contain a substance which stimulates the growth of rats, maintained on a full synthetic diet, to approximately twice the normal rate. This accelerative growthresponse is relatively more marked in the male than in the female. It has been transmitted from parent to offspring by the feeding of liver to the parents, and the stimulation of growth is greater under these conditions than when the liver is fed directly to the young. This growth-promoting principle, according to Mapson’s observations, is distinct from hitherto known accessory food factors. Preliminary investigations show that it is soluble in water and is not precipitated by high alcohol concentrations. Commercial liver extracts such as Eli Lilley No. 343 contain only traces of it. A beneficial effect of feeding fresh ox liver has also been noted in connexion with lactation ; 30 per cent. only of the control animals succeeded in the rearing of their offspring, whereas no such failure of lactation occurred in those litters whose parents received liver in supplement to the basal diet. Evidence of some stimulation of ovarian activity by the feeding of liver is indicated by the readiness with which the animals breed and the increased numbers of young born in the liver-fed litters. Whether the substance active in promoting the growth rate is identical with that stimulating lactation remains to be determined, and a fuller account of the work is shortly to be published. IN
