Engler und K. Prantl. Royal, 8°. Leipzig : Wilhelm Engelmann. The first two fascicles of this important work are at hand. Each fascicle is to consist of 48 pp., and it is expected that about sixteen parts will appear yearly, which will complete the work in six or seven years. The first part is to embrace the Cryptogams,...
Page 282 - De Bary. Observations were undertaken by Mr. Arthur Shipley, under the auspices of the Royal Gardens. The favoring atmospheric conditions are heavy dews or rains, followed by warm, moist, calm weather, and the absence of direct sunshine and cold winds. The life history of the fungus is well known to botanists, with its internal parasitism in the leaves, its conidial branches protruded through the stomata, and its reproduction by asexual and sexual spores. It is suggested that onion plants should...

How many times has he crossed the ocean that he might more carefully study European herbaria, and better know the leading men in his own department! In examining, reviewing and sometimes gracefully correcting the labors of others, what a shrewd, honest and urbane critic has he proved himself to be! How cheerfully, many years ago, among his own western countrymen was he the first of all to greet the rising sun of our own Darwin, believing his theory...
