336 CONSERVATION AND CORRELATION OF VITAL FORCE. 
in Fragaria vesca L. I quote him almost verbatim. ‘ When it 
does not produce stolons, the number of flower spikes is increased, 
and, as they cannot run as stolons, they make up for this by con- 
tinual axial production, bearing a succession of flowers through 
the whole season.” 
“ Sometimes the runner party will so get the upper hand that the 
pistils will be entirely suppressed, in which case the runners push 
out with so much enthusiasm as to crowd down and frequently 
destroy their floriferous neighbors. In fact, just in proportion as 
the plant becomes truly fruit bearing, and with a tendency to pro- 
duce a succession of fruit on the same stock, is the tendency to 
produce runners checked.” He then gives a modification of the 
above, but which is still a case in point.* 
The same journal contains a description of a double early saxi- 
frage with a small panicle, double flowers and no trace of either 
stamen or pistil.t 
The animal kingdom would furnish us with still more striking 
illusttations. A fact I had long suspected concerning hydroceph- 
alic children met lately with a most unexpected confirmation in 
the distinct, unequivocal testimony of one of the most distin- 
guished living pathologists. “The process of enlargement in 
these cases is often one of simple growth, and that “indeed to 
a less extent than it may seem at first sight; for it is very rarely 
that the due thickness of the skull is attained while its bones are 
engaged in the extension of their superficial area. Hence the 
weight of an hydrocephalic skull is not much, if at all, greater than 
that of a healthy one; a large parietal bone, measuring nine inches 
diagonally, weighs only four ounces, while the weight of an ordi- * 
nary parietal bone is about three ounces.” { 
In his admirable text-book on “Diseases of Children,” 2d edi- 
tion, page 298, Dr. J. Lewis Smith under head of ‘‘Anencephalic 
Children,” writes :— * The vault of the cranium is absent. There 
is a deficiency of the frontal, parietal and occipital bones, except 
those portions which are near the base of fhe cranium. These por- 
tions are very thick and closely united as if there were the usual 
amount of osseous substance, but instead of expanding into the 
arch, it had collected in an irregular mass at the base of the era- 
nium.”
