The same movement is also going on in other parts of the world ; for instance, botanic gardens have lately been established in Lagos, and the Gold Coast on the west coast of Africa. Botanic gardens in the tropics do the work on the plant side of agricultural departments in temperate climates. They are in themselves experimental stations; and are much more efficient in...

The vibration of the cilia in vigorous spermatozoids is exceedingly rapid and difficult to study. Judging from observation made on certain spermatozoids just starting motion and others which had nearly exhausted their energy, there would seem to be a rhythmic contraction of the cilia which passes quickly from one end of the band to the other. A tremulous...
Page 201 - Such spots never show distinct darker colored specks and rarely any concentric circles, as do the spots made by parasitic fungi, such as Septoria (spot disease) and Heterosporium (fairy ring). Very badly diseased plants, especially when much crowded and growing in damp atmosphere, have more yellowish green leaves than normal, of a more transparent appearance, and usually smaller. The lower leaves of diseased plants in any atmosphere or soil die prematurely and the vitality of the plant is so lowered...
Page 21 - ... is so similar that the nucleus can not be discerned. The motion of the spermatozoids when swimming free in sugar solution is in no way different from their motion when in the pollen tube. The general motion is a continuous rotation of the body, always in the same direction, around an axis passing through the apex of the helicoid spiral. Viewed from the head end or apex of the spiral the rotation is in the direction of the hands of a clock and contrary to the turns of the spiral band. They roll...
