II. F. C. 



Some Minute Animal Parasites or Unseen Foes in the Animal World. By 

 H. B. Fantham, D.Sc, B.A., A.R.C.S., F.Z.S., Lecturer in Parasitology, 

 Liverpool School of Tropical Medicine, and Anne Porter, D.Sc, F.L.S. 

 [Pp. xi + 319. With frontispiece and fifty-six text figures.] (London : 

 Methuen & Co. Price $s, net.) 



The aim of this book is said to be to give a readable and popular but accurate 

 account of the life-histories of some microscopical protozoal organisms which produce 

 disease in higher animals, including man— principally sleeping-sickness, malaria, 

 dysentery, and kala-azar in man, and tse-tse fly disease of cattle and some diseases 

 of fish and bees. The book is meant, not only as a preliminary work for students 

 of science, but for colonists, sportsmen, poultry breeders, fishermen, etc. The 

 work, though small, fulfils this programme admirably. The style is excellent and 

 the book shows throughout how interesting the life-histories of the various 

 parasities can be made. More than that, it will be distinctly useful to medical 

 men and indeed to students of tropical medicine, who will here find an admirable 

 ummary of general information which they should possess. In fact it affords a good 

 opening for the more technical monographs which they will ultimately have to study. 

 At the same time it will be useful to all residents in the tropics, as it shows 

 automatically how many of the most important diseases of man and animals may 

 be prevented. As a matter of fact the information given ought now to lie within 

 the general knowledge of every educated person in warm countries, since it is 

 certain to be more useful to such than many of the facts which are so laboriously 

 instilled into us all in youth. The passages on evolution in parasitism, the 

 diseases of grouse and bees, and of the parasities of dysentery are specially within 

 the province of Dr. Fantham to write about. In can be safely said of the book— 

 what cannot be said of all such works— that it is both learned and extremely 

 interesting. 



The Internal Secretory Organs : their Physiology and Pathology. By Prof. Dr. 

 ARTUR BlEDL. English Translation by LlNDA FORSTER. [Pp. viii + 606.] 

 (London : John Bale, Sons & Danielsson, Ltd., 1913. Price 21s. net.) 



Prof. Biedl's book is remarkable not alone for the store of information contained 

 in it, but especially for the masterly way in which it is arranged. By reference to 

 some five thousand original papers the author gives a wide and detailed survey of 

 his subject. Again and again one is forced to admire the skill with which dis- 

 crepancies between the results of different workers are shown to be explained 

 by researches carried on in another direction. The development of our know- 

 ledge of internal secretions illustrates in a striking way the reciprocal relations 

 between physiology and pathology, clinical medicine and comparative anatomy. 



And a perusal of Dr. Biedl's book makes one realise that a new limb of the 

 nascent science comparative physiology is coming to light in the study of the 

 various effects produced by removal of homologous organs in different species of 

 animals. By argument chiefly from the author's experiments on elasmobranch 

 fishes, a strong case is made out for the vital importance of the cortical portion 

 of the suprarenal glands. Biedl's treatment of this obscure subject should 

 stimulate further research on the " inter-renal " tissue. 



Throughout the book stress is laid on the peculiar correlation which appears to
