Diatonic scale

Definition and stakes

Benjamin Ives Gilman,  The Philosophical Review (1892)

“ It proves that in the series of alternate groups of two and three tones separated by hemitones, which constitutes the diatonic scale, there is a certain note (viz. that below the group of three tones, or F) , and only one, whose hemitone displacement upward will leave the order of the diatonic form; and one, and only one (viz. that above the group of three, or B) , whose displacement downward will have the same result ”

“ This fact is made use of in practical medicine, as, when administration of food by the mouth is impossible, patients are frequently kept alive by the giving of nutrient enemata. That the food thus given is absorbed is shown by the increase of nitrogen excretion in the urine. In the large intestine very little absorption of nutrient matter takes place under normal conditions, mainly of course because most of the absorb able material is removed whilst the food is in the small intestine. That protein matter can be absorbed is shown by the above statement regarding nutrient enemata. ”

“ In the stomach there are no enzymes acting on carbohydrates, but the digestion may continue under the influence of swallowed saliva for a time. In the pancreatic juice there is another amylase, which completes the splitting of starch to maltose, and then the intestinal maltase can reduce this to glucose, which will be absorbed. Cellulose cannot be digested and simply serves to add bulk to the diet.
Digestion of fat.—A fat is made up of two parts, one a fatty acid, the other glycerol. Fat cannot be absorbed by the body until it is split into these two parts.
