VI PREFACE. 



buted to this department of Medical Science and 

 Biology. The titles of these fragments and more 

 sustained efforts I have thrown together in an 

 Appendix, and in this shape they will at least have 

 the advantage of expressing the sum of my felt 

 indebtedness to editors and to other learned and 

 liberal-minded persons who, throughout a period of 

 nearly twenty years, have generously and persistently 

 encouraged me in these researches. 



As it is now too late for me to allude to the 

 subject elsewhere in these pages, I wish particularly 

 to call attention to the very recently issued " Seventh 

 Annual Report of the Sanitary Commissioner with 

 the Government of India." 



From, Dr. Cunningham's Report it appears that 

 Dr. Oliver, of the Royal Artillery, at Jullunder, has 

 succeeded in experimentally rearing the Tania 

 mediocanellata in a low class Mahommedan syce and 

 in a Hindoo boy, by the ingestion on their part of 

 beef-measles; thus affording most interesting con- 

 firmation of the truth of certain practical conclu- 

 sions which I have enforced on other grounds in my 

 Cantor Lectures and in the earlier pages of the 

 present treatise.
