ments come about, a
chronic and acute tuberculosis of the testicles has been distinguished.
The former is the more frequent, the latter of rare occurrence.

The sexual functions may remain unchanged if only one testicle is
diseased, but are generally ruined if both epididymes are affected,
because the secretion of the semen is then interrupted by the stopping
up of the vas deferens. In some cases the sexual function may be
interrupted for a time only and may then be resumed.

The treatment before this has been surgical, in which the diseased parts
were carefully removed, and where this was impossible, even castration
(removal of the testicle) was performed. Without doubt Koch's method
will cause great changes in the method of treatment here also.

Finally we must include in our reflection the well-known disease of
children, _scrofula_. Although the same is not a form of tuberculosis in
the sense of the diseases just considered, still tuberculosis and
scrofula have the most intimate relations. Scrofula is only too often a
precursory stage of tuberculosis.

The manifold scrofulous affections, such as inflamed eyes, diseased
ears, skin diseases, catarrh of the nose, pharynx or bronchials,
inflammation of the joints and suppuration are not caused through the
cooperation of tubercle-bacilli. But here the same find an excellent
soil for growth and propagation, and they use the same to the full
extent and so give the impetus for the development of tuberculosis.

Scrofula is one of the most frequent diseases, it is spread over the
whole world. It occurs more seldom in the tropics than in the north.
Furthermore it is more frequent in a cold and damp climate than in a dry
one. Elevation has no influence on the development of this disease.
Scrofulous individuals are found in the mountains as well as in the
plains.

Scrofula principally attacks children; it occurs most frequently in the
time from the second to the fifteenth year. Rarely earlier developed
scrofula drags beyond the age of puberty or more advanced manhood. Sex
has no particular influence on the development of scrofula.

In many cases this particular disease is _inherited_. The following
causes are considered in the inheritance of scrofula: great age, close
relationship and infirmity of the parents; but the germ of scrofula is
planted in the child by parents that are themselves afflicted with
tuberculosis or scrofula. This is most frequently observed in children
