The author has examined 1000 lachrymal bones and the soft parts of over 300 orbits, and has deduced therefrom notes on the following points:— I. Cases of absence of the lachrymal bone. II. Rudimentary conditions:—α . Development of an orbital plate only.β . Division into two detached ossicles.γ . Development of a crest only.δ . Fenestration.ε . Presence of marginal fontanelles. III. Varieties in outline, suturation, and frequency of ankylosis. IV. Varieties of crista:— A. Simple lamellar forms with no crest. B. Simple carinate forms. C. Carino-acuminate forms. D. Carino-hamate.
