 consists of a mixed preparation of thymus cells, the nuclei of which 

 are stained by iron hematoxylin, and lycopodium powder. After 

 administration, the lycopodium, which is readily recognized, is sought 

 for in the stool and when found that portion is examined for the stained 

 thymus cells. Their statement is as follows: If stained nuclei are 

 not found in the feces after an intestinal transit of sufficient duration 

 (at least six hours) normal pancreatic function (external) is indicated.

18. Einhorn's Bead Test. 1 This is a method for testing the digestive func- 

 tion. In some respects it is similar to Sahli's desmoid reaction (see Gastric 

 Analysis). The procedure consists hi wrapping the material under examination 

 (catgut, fish-bone, raw beef, cooked potatoes, thymus gland or mutton fat, etc.) 

 in gauze to which glass beads of various colors are attached and enclosing gauze 

 and beads hi a gelatine capsule. 2 The gelatine capsule is swallowed and the 

 beads serve to facilitate the separation of the gauze from the feces. The residue

2 Ordinarily two substances are attached to each bead, three beads tied together and 

 enclosed in one capsule. Test capsules may be obtained from Eimer and Amend, New York.
