Abstract: When the canned goods of sardine or mackerel are made, the slime are secreted from the fish flesh and it makes afilthy appearance. Is the slime absolutely innoxious? It is a well-known fact that the slime secreted by eel, wels or loach was reduced to powder and was exported as the tonic to Manchuria and North China. Does the case bring to a resolution about this problem? Leiognathus argentea Lacepede is a fish easy to seize in this district and the slime secreted from the surface is large in quantity. We have made biochemical researches on the slime secreted by Leiognathus argentea Lacepede owing to the fact that the fish are easily caught. The captured fish must be put into the distilled water and it will secret a large quantity of the slime in the excess of its pain. Into the fluid after the fish is taken off, some alcohol is poured, then the precipitation can be seen. If this precipitation is pulverized, and is investigated, this can be recognized as a kind of mucoid. By means of paper chromatography, we can find that the mucoid contains cystine, arginine, serine, glycine, aspartic acid, alanine, tyrosine, proline, valine, phenylalanine, carbohydrate and what that. If the powder of this material is extract by the distilled water, and then the acid is added, the precipitation is observed. If the excess of acid is added, the former precipitate disappear. On that occasion if the distilled water is added afresh, the solution become dilute and the precipitate present itself again. This matter is beyond doubt the mucine.
