PREFACE. 



The nature of the present work having been 

 sufficiently indicated on the Title Page, it is 

 unnecessary for me to occupy the reader's attention 

 with any lengthened prefatory remarks. 



I feel, however, that I cannot permit its issue 

 without recording my deep sense of obligation to 

 Dr. Davaine, of Paris, the author of one of the best 

 modern treatises upon Entozoa,^ for the disinterested 

 and unconditional manner in which he gave me per- 

 mission to make use of any portions of his work ; 

 and to Messrs. Bailliere and Son, the proprietors 

 of the copyright, as well as the publishers, of 

 Dr. Davaine's treatise, for a similar privilege, of 

 which I have, as will be seen upon a perusal of the 

 following pages, largely availed myself. 



It also affords me much gratification to express 

 here my warmest thanks to those colleagues and 

 friends who have kindly placed at my disposal 

 numerous facts and cases, having especial reference 

 to the subject of Entozoa.
