If it's absent? The thought makes me shiver! But now it would seem, if I eat carotene, I can make the darn thing in my liver. Bi, thiamin, and B2, a flavin, Play a chemical role, enzymatic; B's a, 4, and β have gone back to the hive, Of which I approve most emphatic. Be (pyridoxine) acts like antitoxine, Curing rats with sore paws and red skins; Nicotinic, the acid, now makes people placid, When once they have been pellagrins. Some folks react splenic, without panto thenic, Because their dark hair starts to gray; Without cevitamic, they lie in a hammock And take pills and pellets all day. And now, if you please, they say we've two D's, That we need to cure rickets and jitters; And E, a sterol (alphatocopherol), Causes rats to produce many litters. Vitamin F is ignored by the chef. When you're fat and your tissues are flaccid; But rats become thin with a rough in flamed skin, Through the lack of linoleic acid. You may be a good feeder and still be a bleeder, If you lack blood prothrombin, they say; But it makes you feel swell to know you'll get well If the doctor has vitamin K. L'Envoi I don't mind addressing the drug store clerk In vitamin terms alphabetical; But it sure is terrific to be scientific Using three-dollar terms, hypothetical. R. ADAMS DUTCHBR

GLYCERINE
Τ Μ PORTS of caustic soda into the Philippine Islands last year increased to 7,154 metric tons worth $379,600, com pared with 4,204 tons at $206,600 in 1939. The expansion was probably caused by greater demand from soap factories. Practically the only competitor of the United States in recent years has been Japan and even that has been unimpor tant. In 1937 receipts from Japan amounted to 7 per cent of total consump tion and the caustic soda was used by a few of the household soapmakers in the villages. I n 1939 and 1940 only 6 and 5 tons, respectively, originated in Japan.
