 meeting for the formation of the American Iris Society was held at the Museum Building of 

 the New York Botanical Garden, Bronx Park, New York, on January 29, 1920. Sixty persons 

 were present, among whom were many of the trade, and amateur Iris specialists. Dr. N. L. 

 Britton, Director of the New York Botanical Garden, delivered the opening address. He 

 told of the Iris garden begun in the New York Botanical Garden, and invited members of the 

 newly-formed Iris Society to make free use of the library of the Botanical Garden. — The 

 work of the Iris Society has been carefully planned. There will be test and exhibition gar- 

 dens established, Iris shows with suitable prizes, and investigations made in history, classi- 

 fication of garden varieties, culture and pests of the Iris. A constitution was approved and 

 officers elected of whom John C. Wister of Philadelphia is president, and R. S. Sturte- 

 vant of Wellesley, Massachusetts, is secretary. — L. A. Minns.

VEGETABLE CULTURE 



536. Olmstead, W. H. Availability of carbohydrate in certain vegetables. Jour. Biol. 

 Chem. 41 : 45-58. 1920. — The amount of carbohydrate available to the body from certain 

 vegetables, usually used in low carbohydrate diets for diabetic patients, was determined 

 (1) by the use of diastase and copper reduction, (2) by feeding to phloridinized dogs. The 

 results by these two methods were — cabbage (1) 4.4 per cent, (2) 5.0 per cent, cauli- 

 flower (1) 2.8 per cent, (2) 3.4 per cent, spinach (2) 1.2 per cent, lettuce (1) 1.0 

 per cent. The amount in cabbage was reduced about 90 per cent by thrice cooking. — G. B.
