x TRANSLATOR'S PREFACE. 



the manuscript and alterations of the author were placed in my 

 hands. The additions and emendations were so numerous as to 

 extend in the first volume alone to eleven sheets of the translated 

 work. The labour of translating this quantity of new matter was, 

 of course, considerable, but this labour was greatly increased from 

 its having to be done from the author's manuscript. Nearly the 

 whole of the already completed manuscript had also to be revised, 

 for the insertion of the author's corrections. Whilst this labour 

 was going on, in the spring of the year, an attack of illness 

 compelled me to forego for some weeks all literary labour. 

 These circumstances will explain the delay that has occurred in

 on Anatomy at St. Thomas's Hospital, has kindly forwarded to 

 me a proof of his unpublished c Memoir on Cysiicercus cellulose, 7 

 from which I have made several extracts. Professors Busk and 

 Owen have kindly permitted me to use their manuscripts in the 

 cases recorded in Appendix B. I am also obliged to Mr. 

 Curling for his communications on the subject of the worm 

 referred to in Appendix C. 



As is usual, I have left all Latin descriptions as in the original. 

 I have also done this in the case of prescriptions occurring where 

 the treatment is referred to. Some of the abbreviations, as Avell 

 as the remedies, will undoubtedly be as puzzling to the reader as 

 to myself, but I preferred allowing them to stand rather than to 

 run the hazard of giving a wrong interpretation to that which 

 laid out of the province of the translator. 



I now turn to the scientific theory involved in some parts of 

 this book. Although written by a medical man, engaged in 

 practice, and with a thoroughly practical aim, some of the most
