7th. Pyrotechnic manipulations.

First.—Study of Samples of Mineralogical Specimens.

This study has for its object the determination of the kind of minerals described in the course. It is made in s of ten or twelve Sub-Lieutenants and by attendances of one hour, each Sub-Lieutenant being called upon to reply at least three times.

Second.—Study of Geological Maps, followed by a Memoir.

The study of geological maps will consist in indicating, by conventional colors, the different geological formations of a lithographical map, and to make a in a particular direction. The map will be the same for all, and it will be conceived so as to correspond with the geological formation of France, but the s will differ for each student.

An explanatory memoir will have for its object to call the attention of the Sub-Lieutenants to the most salient facts which will be placed in relief by this study.

One attendance in the halls of study will be devoted to this work.
