PREFACE TO SECOND BIBLIOGRAPHY 



OINCE the publication of our first Bibliography (1911) a great many 

 ^ papers have appeared which deal with ticks and their relation to 

 disease. We have, moreover, collected a number of references which 

 were omitted from the previous Bibliography. 



We are indebted to Med.-Rath Dr J. Chr. Huber (Memmingen) 

 for sending a number of titles which we should probably have over- 

 looked. W T e have also to thank Mr W. E. Collinge, M.Sc, for communi- 

 cating a few titles. 



The present Bibliography contains 462 titles. 



Our comments on the contents of the papers cited are enclosed 

 in [] brackets. 



As stated in the preface to the first Bibliography, we shall be very 

 grateful to readers who may draw our attention to errors or omissions.
