A glance at this table will suffice to convince one that the 

 results obtained by the different authorities quoted cannot be 

 rigidly compared, since no two of them have worked under 

 precisely the same conditions with exactly the same object in 

 mind. It is believed that these factors explain in a large degree 

 the wide differences in the percentages of entamcebic infection 

 reported ; namely, from to 76 per cent. 



Among the factors to be considered in making examinations 

 for entamoebae not the least important is the stage of develop- 

 ment upon which a diagnosis is rendered. The time is at hand 

 when a diagnosis should be given not only upon the presence 

 of active, but also upon that of quiescent or encysted forms. 

 It is my experience that active forms only or encysted forms 

 only may be present in a specimen. The quiescent forms, on the
