Rare and beautiful Pavlov letter discussing current research on digestion. In part, translated: "Would it be possible for me to publish my laboratory's physiological work about the digestive system in your journal? The work on the effect of chemical stimuli (irritation) of the pepsin-forming glands by Dr Gross from Heidelberg is ready for the press. Another work by Dr Edelmann about the movements of the stomach as well as the conversion of the gastric contents into the duodenum is almost completed...." Pavlov conducted some important investigations into the mechanism of artificial conditioned reflexes at this time.
