had considerable experience in this line of work, it was believed 

 that reliance could be placed upon their findings. These five 

 protozoologists were : 



A. H. Campbell, B.Sc, 2nd Southern General Hospital, 



Bristol. 

 T. Goodey, D.Sc, 1st and 2nd/lst Southern General 



Hospitals, Birmingham. 

 E. C. McLean, M.A., Beading War Hospital. 



Mis^ M. M. Nutt (Bathurst Student, Newnham College, 



Cambridge), Leeds and Shefiield Military Hospitals. 

 A. G. Thacker, A.R.C.S., Kitchener Hospital, Brighton. 



Mr. Campbell and Mr. Thacker were working under grants 

 from the Medical Research Committee : the three others were 

 in the service of the War Office. They all expressed their 

 willingness to collaborate in the undertaking, and were then 

 supplied with cards for the recording of their findings. These 

 cards, which were issued by the Medical Research Committee, 

 were designed — by myself, in consultation with Sir Walter 

 Fletcher — so as to indicate the kind of information required, and 

 in order to enable the examiners to record their findings, and 

 such essential facts as they could elicit regarding the histories 

 of the cases studied, in a uniform manner and with economy of 

 space and time. The form of the card is shown on p. 14— its actual 

 measurements being 12-5 x 20cm. — and it maybe added that 

 it appears to have fulfilled its objects. Apart from this pro- 

 vision for collecting and correlating the results, all arrange- 

 ments for the work were left in the hands of the protozoologists 

 themselves. They were all able, with the assistance of the 

 medical officers in charge, and in some instances with aid from 

 the Medical Research Committee and the Local Government 

 Board, to obtain the necessary material from various local 

 institutions. 



As all the workers were engaged simultaneously in the routine 

 work of diagnosis for militarj' hospitals, they could devote only a. 

 fraction of their time, as opportunities occurred, to the examination 

 of civilians. There were naturally many difficulties to be sur- 

 mounted — differing from time to time and from place to place — 

 and the several workers did not all enjoy equal facilities for the 

 prosecution of their inquiries. This explains, to a large extent,, 

 the inequality of their results. Nevertheless, every worker was 

 able to investigate a certain number of cases ; and in due course 

 each was able to submit a report of the results. The largest 

 series of cases — and the fullest report — came from Miss M. M., 

 Nutt (Leeds and Shefiield) ; but she had already begun her inquiry, 

 at my suggestion, before the matter was taken up by the War 

 Office Committee. The reports are all printed here for the first 

 time (see Chapter III), and deal, in the aggregate, with the 

 findings from the examination of the stools of over one thousand
