The debate continued well into the twentieth century. In 1911 William Bayliss concluded that enzymes are not proteins. Purified enzymes contain no phosphate, and therefore they cannot be nucleoproteins. They must belong to an as yet unknown class of compounds. " ... 

On the afternoon of 16 January 1901 William Bayliss and his brother-in-law Ernest Starling tested Dolinsky s thesis. Charles Martin watched them at work in the physiological laboratory of University College London, and his often-repeated account can be repeated once more ... 

Seventy years later, in 1894, a student of Pavlov, Ivan Leukich Dolinsky, rediscovered this effect and noted that acid in the duodenum of the dog stimulated pancreatic secretion. It was on the basis of the earlier French observations that William Bayliss and his brother-in-law, Ernest Starling, on the afternoon of January 16, 1901, tested Dolinsky s thesis and proved the existence of chemical messengers (hormones) that regulated secretion.
