PREFACE TO THE BIBLIOGRAPHY 



IT was our original intention to issue the complete bibliography of 

 the Ixodoidea after all the parts of this work had appeared, but, 

 owing to the unavoidable delay attending the publication of the separate 

 parts and the present need of the bibliography for purposes of reference, 

 we find it inadvisable to retard its publication any longer. 



This bibliography deals with ticks and their relation to disease: 

 we trust that it will prove useful to workers engaged in the study of 

 the subjects to which it relates, for it has entailed much labour owing 

 to the literature being very scattered. Our bibliography contains 

 2004 titles and includes full references to all the important papers 

 hitherto published on ticks, as well as to papers of lesser merit. A 

 few papers dealing more especially with the diseases which ticks convey 

 have been included because of the general information they contain 

 and the aspect they afford of the important part which ticks play in 

 pathology ; some of these papers, moreover, contain useful bibliographies. 



Since it is certain that references to,' future literature will be 

 required in connection with the forthcoming parts of this work, we 

 propose to append any such references in the form of Addenda at the 

 end of the succeeding parts so that they can be detached and added to 

 the main bibliography. We would advise our readers to bind the 

 bibliography separately ; some blank pages, provided at the end, are 

 intended for the reception of any additional references supplied on 

 Addenda slips. 



Throughout the book the Harvard System of References to the 

 bibliography has been adopted. Wherever an author has been cited in 

 the text the date of publication (and usually the page) has been added 

 in brackets. In the following bibliography the names of the authors 

 are given in alphabetical order, the names being followed by the date
