444 Longevity of Brain-Workers. [October, 
2. A good constitution usually accompanies a good brain. 
The cerebral and muscular forces are correlated. This 
view, though hostile to the popular faith, is yet sound and 
supportable. A large and powerful brain in a small and 
feeble body is a monstrosity. ‘‘ In monstrosities Nature 
reveals her secrets,” says Goethe. When a specially small 
and delicate frame sustains a specially large and potent 
brain, men wonder, as at a tree bowed to the earth by the 
weight of its over-abundant fruit. Everywhere Nature is a 
slave to the necessity of correlation or correspondence of 
parts and organs with each other; and unless she heeds it, 
all organised life would become awry and misshapen. In 
all the animal realm, there is a general though not unvary- 
ing relation between the brain and the body of which it is a 
part and to which it ministers. A hundred great geniuses, 
chosen by chance, will be larger than a hundred dunces 
anywhere—will be broader, taller, and more weighty. In 
all lands, savage, semi-civilised, and enlightened—the ruling 
orders, chiefs, sheiks, princes by might and mind, scientists, 
authors, orators, and great merchants, weigh more than 
the slaves, peasants, and riff-raff over whom they rule; and 
bear the evidences of their superiority so clearly that they 
need no other insignia. In any band of workmen on a rail- 
way, you shall pick out the ‘‘ boss” by his size alone, and 
be right four times out of five. Those monstrosities where 
genius is cabined in a small body show the law by their 
very rarity. 
3. Great men who are permanently successful have correspond- 
ingly greater will than common men ; and force of will is a 
potent element in determining longevity. The one requisite for 
great success is “gvit;” and, more uniformly than any 
other single quality or combination of qualities, it is found 
in those who attain high distin¢tion. In the grand struggle 
for existence, it is everywhere the stiff upper lip that con- 
quers; the timid and the yielding are cowed and crushed, 
and over them rise the courageous and the strong. In cer- 
tain special lines, as poetry and art, extraordinary gifts 
may, as it were, draw their possessor into fame with but 
little effort of his own; but the highest seats in the temples 
both of art and poetry are given oniy to those who have 
earned them by the excellence that comes from consecutive 
effort, which everywhere tests the vital power of the man. 
That longevity depends not a little on the will, no one will 
dispute. The whole subject of the relation of mental 
character to longevity is one of vast interest, and is too 
far-reaching to be here discussed; but this single point
