As a very probable element of that law, it might be 
- said that among one hundred notable personages who 
exercise the activity of Mind, there are, approxima- 
-—tely, twenty four men of science, eight poets and seven 
of the various classes of writers. 
V. C. Approximately seven per cent of notable men 
have suecumbed to violent deaths. 
VL C. Violent deaths are unevenly distributed 
«among the different groups; of the relative total, ap- 
proximately, 22 9/¿ pertain to Warriors; 19 9/¿ to Kings 
and other personages; 14 9/¿ to Statesmen, 4.5 9/2 to 
Theologians; 3.897 to Poets and 2.3 9/7 to Musicians. 
For the first three groups, the relation of causality, 
"between the line of occupation and the number of vio- 
lent deaths, is evident: not so evident, for the fourth 
group, but almost as certain; simply probable for the 
last two, and does not exist in regard to the other 
groups specified in the Table. | 
- The proportions in these other groups are insignifi- 
cant (null and void in that of Historians), and are due 
only to mere accidents or to the relative personages 
having been engaged either in politics or war. 
VII. C. The general average of human life devoted 
to mental work, is above 68 years, and the average years 
of Scientists, Lawyers and Historians is more than se- 
venty. 
Statesmen, Theologians, Physicians, Literary. men, ' 
- Artists and Warriors are also above the general avera- 
ge, and, to close, Kings and other personages occupy 
the last place on the scale of longevity. 
VIII. C. The general average, and therefore the ave- 
rage pertaining to the different groups tends to increase 
visibly every day under the influence of Hygiene and 
the much improved conditions. of life which civilized 
communities are adopting. 
IX. C. Allowing the tendeney shown in the above con- 
clusion, and not considering the cases of violent deaths, 
the probabilities for persons, who are actually exerci- 
sing their mental powers, of attalning sixtv years or 
more, may be estimated at 78 9/7, against 229/47 at... 
45 0/0, against 55 9/7, those of attaining more than 70 
years; and only 209/47, against 80 9/7, those of attaining 
80 years, or more.
