Salomon² in 1902 reported similar observations and again in 1908 confirmed Deucher's work.

The same author⁴ in 1912 again found conclusive evidence that there was a large amount of lecithin excreted in two cases of obstruction of the pancreatic duct. Schumacher,⁵ on investigating the stainability of lecithin, found, in agreement with earlier histochemical observations, that the fuchsin series are the best stains for lipoids, victoria blue being the finest. He found that
