This paper reviews the recent studies on the louse [Pediculus 

 humanus] and its connection wath the micro-organism known as 

 Rickettsia frowazeki. The author's investigations have enabled him 

 to identify the organisms taken from healthy lice with those previously 

 recorded by other authors and described by da Rocha Lima under 

 this name. Seventy individuals of Pediculus humanus, of which more 

 than fifty were thus infested, were allowed to feed on the author with- 

 out producing any infection. The fact that this organism, which appar- 

 ently cannot develop in culture media, is found in the blood and certain 

 organs of patients does not prove it to be the agent of exanthematous 

 typhus ; it might on the contrary have been inoculated by the louse 

 without having any pathogenic action. Lice parasitised by cocco- 

 bacilU remain infected all their lives. Typhus-infected lice are active 

 from the 8th to the 10th day and it would be interesting to know how 

 long their infective power lasts, in order to determine if there is in 

 certain cases any relation between the development of the typhus 

 virus and that of Rickettsia.

The genus Culicoides, Latr., is defined in this paper and C. pulicaris, 

 L., and C. fasciipennis, Staeg., are recorded from Allier and Ram- 

 bouillet respectively. Species of the genus Simulium, Latr., recorded 

 by the author from France and Corsica include S. hirtipes, Fries, 

 S. ornatum, Mg., S. nanum, Zett., S. latipes, Mg. {aureum, Fries), 

 S. maculatum, Mg. {lineatum, Fries), S. columbaczense, Schonb., and 

 S. vittatum, Zett., var. delphinense, var, n., described from two females 

 captured in Dauphine.

The author's object in writing this book has been, to quote the 

 preface, " the education of the people as a whole in the subjects of 

 vital importance with which it deals and an increased interest in this 

 field of scientific work." He does not claim to have effected anything 

 in this volume beyond a compilation of recorded facts, but holds the 

 opinion that of equal importance with research work is the careful 

 dissemination of scientific knowledge in a suitable form for the general 

 public, so that they may not be left hopelessly behind in the progress 

 of science. The imjjortant facts of parasitology, as related to human 

 disease, are presented in such a manner as to make the book readable 

 and useful to public health and immigration service officers, to
