t if a hairy man is not sensual
he is strong: _vir pilosus aut libidinosus aut fortis_. The Greeks
insisted on the hairy nates of Hercules, and Ninon de l'Enclos, when the
great Conde shared her bed without touching her, remarked, on seeing his
hairy body: "Ah, Monseigneur, que vous devez etre fort!" It may be doubted
whether there is any exact parallelism between muscular strength and
hairiness, for strength is largely a matter of training, but there can be
no doubt that hairiness really tends to be associated with a generally
vigorous development of the body.

Although the observations concerning hairiness of body as an index of
vigor, whether sexual or only generally physical, are so ancient, until
recent years no attempts have been made to demonstrate on a large scale
whether there is actually a correlation between hairiness and sexual or
general development of the body. Some importance, therefore, attaches to
Ammon's careful observations of many thousand conscripts in Baden. These
observations fully justify this ancient belief, since they show that on
the one hand the size of the testicles, and on the other hand girth of
chest and stature, are correlated with hairiness of body.

Ammon's observations were made on nearly 4000 conscripts of the
age of 20. From the point of view of the hairy system he divided
them, into four classes:--

I. To which 6.1 per cent, of the men belonged, with smooth
bodies.

II. Including 25.3 per cent., only slight hairiness.

III. 53.8 per cent., more developed hairy system, but belly,
breast and back smooth.

IV. 14.7 per cent., hair all over body.

V. 0.1 per cent., extreme cases of hairiness.

The beardless were 12.1 per cent., those with no axillary hair 9
per cent., those with no hair on pubis 0.4 per cent. This
corresponds with the fact that hair appears first on the pubis
and last on the chin.

In the first class 69 per cent, were beardless, 54 per cent,
without any axillary hair and 6 per cent, without pubic hair. In
the second class 24 per cent, were beardless, 17 per cent,
without axillary hair. In the third class 3 per cent, were
beardless and 3 per cent without axillary hair.

Below puberty the diameter of testicles is below 14 millimeters.
There were 13 conscripts having a testicular diameter of less
than 14 millimeters. These infantile individuals all belonged to
