EXPERIMENTS ON FECES 



i. Macroscopical Examination. If the stool is watery pour it into a shallow 

 dish and examine directly. If it is firm or pasty it should be treated with water 

 and carefully stirred before the examination for macroscopical constituents is 

 attempted. The macroscopical constituents may be collected very satisfactorily 

 by means of a double layer of cheese cloth. 



A Boas sieve (Fig. 69) may also be used to collect the macroscopical 

 constituents of feces. This sieve is constructed of two easily detachable 

 hemispheres which are held together by means of a 

 bayonet catch. In using the apparatus the feces are 

 spread out upon a very fine sieve contained in the 

 lower hemisphere and a stream of water is allowed to 

 play upon it through the medium of an opening in 

 the upper hemisphere. The apparatus is provided 

 with an orifice in the upper hemisphere through 

 which the. feces may be stirred by means of a glass 

 rod during the washing process. After 1 5-30 minutes 

 washing nothing but the coarse fecal constituents 

 remain upon the sieve.

2. Microscopical Examination. After the ingestion of 

 the test diet (see Schmidt diet above) for several days, a 

 specimen of the movement is collected. Any gross abnor- 

 malities are recorded hi the form, consistence, and char- 

 acter of the stool as well as the admixture of certain pathological elements 

 such as pus, blood, mucus, and parasites. The movement is then rubbed out 

 on plates and the presence of undigested food-stuffs sought for. Normally the 

 test diet is almost completely digested and no gross undigested material is 

 found. Therefore the presence of these macroscopic rests is in itself evidence
