cates a great deal of interest on their part. The root of San- 
guinaria Canadensis offers a very satisfactory material for the 
- study of pigment-cells ; young prothalli of Equiseta from spores 
germinated on moist sand, were easily obtained and proved of 
great interest; the pollens of several plants were critically stud- 
ied; hop leaves are recommended for chlorophyll and cucumber 
placente for inulin. Part II is devoted to a record of observa- 
tions and experiments by the professor, and accounts are given 
of the germination of Ergot (Claviceps purpurea, Fr.,) from Ely- 
mus Canadensis; the adhesive bands of Szlene antirrhina,; on 
the insectivorous habit of Sz/phium perfoliatum , observations on 
Cnicus altissimus; a calendar of leafing of trees and shrubs, the 
time of first blooming of spring and early summer plants ; notes 
on the Peronospore and the Ustilaginee ; a list of Colorado Fungi 
collected with Dr. Bessey in Central Colorado in 1886, and many 
other matters of botanical and agricultural interest.
