Ill Botany AND ZOooLoGy. 
. Rapid Growth—A. W. Bennett says, of a plant of Vallis- 
siipin spiralis: The first flower-bud made its appearance in my 
aquarium this year on July Ist, the pedicel rte at 3 P.M. appar- 
ently about 1°5 inch long. On the 3rd, at 4 Pp. M., the base of the 
bud just touched the surface of the water, aid “the pedicel was 
about 7 inches long. At 1 P.M. on the 7th {an Saatigbe of ninety- 
three hours), it had. reached the astonishing length of 43 inches. 
og bed was then still closed, and the flowerstalk quite eee 
ot showing yet any tendency tocoil. At 10 A. mu. on the 
the Teagth was 45°5 inches, the flower being then open, and the 
lower on of the flower-stalk so strongly undulating that it w 
most impossible to straighten it. At 11 a. M. on the 10th it had 
Feiched its ultimate length of 48 ces the undulation of the 
nd portion being more strongly mar 
2. Evolutionary Law as illustrated i Abnormal Growth in 
Apple Tree.—Mr. Tuomas Mrruan exhibited some branches 
of a “ Smoke-house” apple tree, which had the cluster of flowers at 
the end hes a young shoot, flowering after the leaves and growth 
had matured, instead of bloo ming in spurs early in spring, and 
denultaverunty with the expansidn of the leaves, as in ordinary 
case were numerous instances of the normal and abnor- 
mal growths on the same tree, the abnormal ones flowering about 
six weeks after the normal ones, but both classes maturing the 
fruit at about the same time in the fall. 
e point he wished ages eit! to draw attention to was that 
when there was a change in one important character, there was 
often change in others Giakay a complete set of characters which 
need nothing but permanence to be regarded as specific. For
