“recorded is entitled to be called strictly scientific. 
` The second publication is Mr. F. L. Scribner's “ Fungus 
Diseases of the Grapevine,” issued by the Department of Agri- 
culture at Washington, D. C. Its principal contents are the 
Downy Mildew (Peronospora viticola), Powdery Mildew (Un- 
cinula spiralis), Black Rot (Physalospora bidwilltt), Anthracnose 
(Sphaceloma ampelineum), Grape-leaf Blight (Cercospora viticola), 
Grape-leaf Spot (Phyllosticta labrusceé). Some good plates ac- 
company the text, and add much to its value. As with the pre- 
ceding report, this one ought to show our younger botanists 
that there is an opportunity for them to do good work in botany 
even.—Charles E. Bessey. 
Vegetable Pathology.—Agriculture demands of botany a 
knowledge of the pathology of vegetation. It is not enough 
that the normal action of all parts of the plant should be under- 
stood; the abnormal and diseased actions must also be con- 
sidered. Unfortunately, the world is full of accidents, of noisome 
gases, of poisonous liquids, of freezing or scorching temperatures, 
of harmful insects, and of destructive fungi. The plant which is 
more or less affected by one or all of these is not the normal 
plant of the vegetable physiologist. The vegetable pathologist 
must build his science upon that of his fellow-worker in vegeta- 
ble physiology, and the results of the labor of both must be laid 
ore modern agriculture for its use. That botany which hopes 
to satisfy the demands of the advanced agriculture of to-day 
must include a knowledge of pathology.—Proc. Soc. Jor Promotion `
