As will be observed, there are cases when three or four very 

 harmful parasites appear in the same individual, all of them 

 demanding a more or less specific treatment. The therapeutics 

 of the intestines, in tropical climates more than anywhere else 

 (so common is its symptomatology), nowadays cannot be pre- 

 scribed merely on the result of clinical observation, without the 

 co-operation of the laboratory. Clinically one may surmise the 

 presence of parasites, just as one may make a cannon at billiards 

 with a strong push and without effect ; with laboratory examina- 

 tion the chances of accurate diagnoses are much greater, and, 

 more often than not, there is the certain identity of the 

 pathogenic agent and consequently of the proper therapeutics 

 to apply. 



Adding those cases in which each parasite was found alone 

 to those where it appeared associated with others, we come to the 

 following figures in the 480 diagnoses made: —
