t nature from rickets. It is probable
that the infant was not at full term. Among the points which the author
has noticed in his description are that the fontanelle was double its
usual size; that the orbits were somewhat deformed; that the two halves
of the lower jaw were already united; and that the ribs were short and
badly formed. He also, of course, draws attention to the shortness of
the limbs, the stoutness of the long bones, and the supernumerary
digits. I find no statement that the skeleton was deposited in any
museum, but it is very possible that it is still in existence in
Amsterdam, and if so it is very desirable that it should be more
exactly described."

In Figure 126, A represents division of thumb after Guyot-Daubes, shows
a typical case of supernumerary fingers, and C pictures Morand's case
of duplication of several toes.

Forster gives a sketch of a hand with nine fingers and a foot with nine
toes. Voight records an instance of 13 fingers on each hand and 12 toes
on each foot. Saviard saw an infant at the Hotel-Dieu in Paris in 1687
which had 40 digits, ten on each member. Annandale relates the history
of a woman who had six fingers and two thumbs on each hand, and another
who had eight toes on one foot.

Meckel tells of a case in which a man had 12 fingers and 12 toes, all
well formed, and whose children and grandchildren inherited the
deformity. Mason has seen nine toes on the left foot. There is recorded
the account of a child who had 12 toes and six fingers on each hand,
one fractured. Braid describes talipes varus in a child of a few months
who had ten toes. There is also on record a collection of cases of from
seven to ten fingers on each hand and from seven to ten toes on each
foot. Scherer gives an illustration of a female infant, otherwise
normally formed, with seven fingers on each hand, all united and
bearing claw-like nails. On each foot there was a double halux and five
other digits, some of which were webbed.

The influence of heredity on this anomaly is well demonstrated.
Reaumur was one of the first to prove this, as shown by the Kelleia
family of Malta, and there have been many corroboratory instances
reported; it is shown to last for three, four, and even five
generations; intermarriage with normal persons finally eradicates it.

It is particularly in places where consanguineous marriages are
prevalent that supernumerary digits persist in a family. The family of
