The authors say of this series that their original object had 

 been ' to examine a number of youths from a higher social class 

 and from better homes than the .Army recruits whom we had 

 previously reported on. We can only say that infections of the 

 various protozoa exist among such persons.' 



I shall not attempt to summarize at this point the many 

 other important facts brought out and discussed in the foregoing 

 reports. All who are interested in the subject with which they 

 deal will read the originals. There are, however, several matters 

 which require detailed consideration, and to these I shall return 

 in the next chapter. It will be more profitable, and much more 

 convenient, to consider these points after the newer results 

 obtained by the other workers have been given. 



B. The I^ater Reports. 



As already noted in the Introduction, the five investigators 

 working for the War Office Committee on Dysentery (see 'p. 13) 

 presented, in due course, reports on their work. They also (with 

 one exception) sent me back the cards — fully filled up, for the 

 most part — with which they had been supplied for the purpose 

 of recording their findings. I have thus been able to check the 

 reports by means of the cards, and in many cases I have added 

 relevant details from the latter when they were not given in the 

 reports themselves. I have also freely exercised my editorial 

 privileges in preparing these reports for press: for it has been 

 possible, and, indeed, necessary, to introduce a greater uniformity 

 of treatment of the material than was possible to the writers of 

 individual reports — unacquainted as they were with the work 

 of one another. I have cast all the tables in the same form, and 

 eliminated or simplified a number of complicated ones when this 

 appeared desirable. I have throughout removed everything 

 which appeared to me superfluous, and have endeavoured to 

 present the essentials as concisely as possible. I have also — as 

 I have, indeed, throughout the whole of the present work — 

 silently corrected the nomenclature of the protozoa to which 

 reference is made, when the names employed have not accorded 

 with current zoological usage. With these modifications, the 

 reports now presented are the work of the authors whose names 

 they bear. Remarks or additions of my own — which mostly 

 consist of supplementary information which I have copied from 

 the cards — are distinguished by being enclosed in square 

 brackets.

Faeces samples were obtained from civilians undergoing 

 treatment for phthisis at two sanatoria, viz. Salterley Grange 

 Sanatorium, Cheltenham, one of the Birmingham Corporation 

 sanatoria, and Cranham Lodge Sanatorium, near Stroud, a private-
