REVIEWS 159 



A joint paper by S. C. Fuller and R. M. Chambers insists that a helpful 

 clinico-diagnostic test of dropping adrenalin into the eye and causing 

 mydriasis enables a distinction to be made between dementia prsecox and 

 other forms of insanity, notably from manic depressive insanity. 



G. B. Hassin endeavours to correlate physical and mental states, which 

 is in opposition to the teaching of Brodmann, the anatomist. 



C. T. La Moure states that a recovery of 2 per cent, occurs in this disease, 

 but Holmes gives the proportion as 10 per cent., which we venture to submit 

 is too sanguine a calculation. La Moure points out that most cases of 

 dementia prsecox come from the towns and not from rural districts, and 

 that the average duration in hospital is about sixteen years. Mental tests 

 upon the Rossolimo formula of testing nine central mental faculties, and 

 carried out by H. C. Stevens, show the Will-power to be deficient and 

 that there is an increased suggestibility, a diminished constructiveness, and 

 a weakened power of observation in all cases of this disease. J. R. Ernst 

 suggests Appendicostomy and "colonic" irrigation as a successful surgical 

 treatment, and B. Holmes agrees, but amplifies the treatment by suggesting 

 normal saline intravenously and glucose also, as well as enemata and baths 

 to aid elimination. He also suggests calcium lactate in gr. x doses. 

 He asserts that cases of the stuporose kind recover completely after 

 repeated lumbar punctures, because it relieves the increased pressure of 

 the cerebro-spinal fluid ; also the venous engorgement and lumbar puncture 

 helps to re-establish the normal arterial circulation. The treatment men- 

 tioned is further supplemented by personal attention to industrial training, 

 so as to kindle an interest and thus neutralise the tendency to mental stag- 

 nation and chronicity. There are many valuable suggestions conveyed in 

 the papers collected in the studies. The volume deserves to be read by 

 all who are interested in scientific medicine and to be studied by those 

 whose duty it is to care for and relieve this most hopeless and depressing 

 illness that can afflict the youth and the adolescent.

The Physiology of Muscular Exercise. By F. A. Bainbridge, M.A., M.D., 

 D.Sc, F.R.C.P., F.R.S., Professor of Physiology, University of London. 

 [Pp. 215, with 22 diagrams.] (London : Longmans, Green & Co. Price 

 los. 6d. net.) 



Prof. Bainbridge's Physiology of Muscular Exercise is a well-balanced 

 account of the adaptations of the animal body to increased muscular activity. 



It deals with the muscles themselves as well as with the associated and 

 co-ordinated circulatory, and respiratory, changes which accompany the 

 inception, and continuance, of exercise, and follow the return of the organism 

 to the state of rest. 



The twelve chapters, each of which is concisely and clearly summarised, 

 are followed by an extensive bibliography. 



The book will be attractive to clinicians, and to athletes, who are inter- 

 ested in the physiology of exercise, and may be cordially recommended to 

 such as a clear exposition of the author's views on the subject.

Food Poisoning and Food Infections. By William G. Savage, B.Sc, 

 M.D., D.P.H. Cambridge Public Health Series. [Pp. viii -|- 247.] 

 (Cambridge : University Press. Price 155. net.) 



That food may be the vehicle of poisoning and infection is very well known, 

 but there is, even amongst medical men, much misconception of the real
