1 Since this paper was read, I find that Landois in the last 

 edition of his " Lehrbuch der Physiologic," 1885, p. 306, 

 accepts without question the results of Von den "Velden and 

 others here summarized. The same authority (p. 311) quotes 

 Fubini and Fiori as stating that potassium iodide impedes 

 gastric digestion. Chambers, in his " Manual of Diet," Phila- 

 delphia, 1875, p. 257, advises that potassium iodide be admin- 

 istered before meals, " as the mixture of the drug with food in 

 the stomach diminishes the efficiency of both."
