Collecting and Examining Parasites 
The collection of parasites calls for certain personal equipment 
and a limited amount of apparatus. Some collectors have a highly 
developed personal equipment. It consists in: 1, an intense and 
persistent interest in parasites; 2, a tremendous curiosity on the sub¬ 
ject, which leads one to scrutinize every suspicious object as a pos¬ 
sible parasite; 3, an equal amount of pertinacity, which impels the 
investigation of these objects until they are definitely proven para¬ 
sitic or non-parasitic and not merely probably one thing or an¬ 
other; 4, a faith and conviction that there are parasites present; 
5, a thoroughness which lets no parasite escape. To collect para¬ 
sites one should be in the mood to collect parasites. Given this, one 
needs only keen eyesight, a small amount of apparatus and a system 
for examination of the host animal. 
Search Everywhere 
As regards a system for examining animals for parasites, one 
must know where to look. So far as time and other circumstances 
permit, look everywhere. Examine all pathological conditions as 
possibly of parasitic nature. Examine all cavities, large and small. 
Assume that the digestive tract always has parasites; that the respi- 
tory and circulatory systems sometimes harbor parasites, and that 
the skeletal, muscular, nervous and reproductive systems may harbor 
parasites at times. 
Superficial Examination Not Sufficient. 
In examining an animal for parasites, the usual postmortem ex¬ 
amination instruments, knives, scalpels, forceps, etc., are necessary. 
In addition an enterotome is essential; it is the one instrument which 
the parasitologist finds indispensable. The intestine is such an im¬ 
portant site of infestation for parasites that the enterotome with
