absent in others. The results may be given in the form of 

 a table. 



TABLE V. SHOWING THE RELATION BETWEEN THE NUMBER OF STRONGYLES 



IN THE CJECA AND BACILLUS COLl AND BACILLUS ENTERITIDIS IN THE 



OTHER ORGANS. 



The points which come out clearly from this table and from 

 other observations are : (1) that when Strongyles are absent 

 from the cseca or are present only in small numbers (less than a 

 hundred), intestinal bacteria, especially Bacillus coli, are not 

 present in the liver or other organs of the Grouse (eleven Grouse 

 one exception); (2) that when a moderate number of Strongyles 

 are present (one hundred to one thousand), Bacillus coli may or 

 may not be present in the organs (twenty-one Grouse) ; and 

 (3) that when great numbers (over one thousand) are present, 

 Bacillus coli has invariably been found in the liver or other 

 organs (twenty Grouse.)
