(4) Asylum Patients. 



Matthews and Smith (1919 a) examined the stools of 207 

 patients in the Lancashire County Asylum, Whittingham. The 

 patients were all males, their ages ranging from 17 to 87. As 

 in the other series, only one examination per case was made. 

 None of the patients had ever been abroad. The findings were 

 as follows : 



Total No. of cases examined ..... 207 



Infected with : per cent. 



Entamoeba histolytica ...... 9-7 



E. coli 45-9 



Endolimax nana ....... 12-1 



Giardia intestinalis ....... 3-i 



CfiiloTnastix mesnili ....... 23-2 



In a later paper Smith (1919) reported his findings from a 

 larger series of cases examined at the Lancashire County Asylum 

 at Eainhill. His results were as follows : 



Total No. of cases examined ..... 504 



Infected with : per cent. 



Entamoeba histolytica 4.2 



E.coli 21.4 



Endolimaa nana . 3-0 



lodamoeba butschlii ....... l-O 



Giardia intestinalis ....... 5-0 



Chilomastix mesnili ....... 6-7 



Trichomonas hominis 0-8 



A few of the patients in this series were examined more than 

 once ; but the figures given were calculated from the results 

 of only one- examination per case — to keep them in line with the 

 others. 



It should be noted that this series is not strictly comparable 

 with the others, as it includes a few persons who had been abroad. 

 It is stated that ' only thirty-four of the five hundred and four 

 patients at Eainhill had, so far as could be traced, ever been 

 abroad': but the findings for the 'British' oases alone are not 

 given, and as the individual histories are recorded for very few 

 cases, it is impossible to estimate — from what is published — 

 how far the inclusion of 'foreign' cases may have influenced 

 the results. 



(5) Uni'veesity and School Cadets. 



A very small series — unfinished — was examined by Matthews 

 and Smith (1919 a) from the University Platoon in an Officers' 

 Training Corps, and older boys from a secondary school near 

 Liverpool. All were males who had never been abroad — their 

 ages being from 15 to 19 years. Results (one examination per 

 case) : 



Total No. of cases examined ..... 41 



No. infected with : 



Entamoeba histolytica ...... 1 



E. coli . . 11 



Endolimax nana . . .... 1 



Giardia intestinalis ...... 1
