This organ furnishes the inclination to construct, to build, and to
invent. It is supposed by many, that this organ of itself is a proof
of the ability to be an operative mechanic, but this is an error;
the office of the organ is only to manifest the desire by which the
intellect is excited to its gratification. To possess a high degree
of inventive power, one must not only possess a large organ of
Constructiveness, but a favourable intellect; and to be a successful
practical mechanic, it is requisite to have along with these two
requisites, a large developement of Form, Size, Weight, &c.
Predominant.--With Constructiveness predominant, one will possess a
high degree of natural ability for planning, contriving, building, &c.
He will take great delight in contemplating works of architecture, and
other subjects of human ingenuity.
Large.--With large Constructiveness and Imitation, one will excel in
making after a pattern; but if Form, Size and Weight are small, he will
be unable to construct from his own invention.
