The following list is worked out for practice _much more fully_ than a medical student would do if he were learning the list in his studies. The medical student would doubtless first objectively identify these nerves in dissection, and then use correlations to help him remember those which his natural memory could not carry. If not a medical student, my pupil may omit this and the previous examples from Quain's Anatomy. THE TWELVE PAIRS OF CRANIAL NERVES.

What advice is here given the medical student? 5. Are you required to learn the twelve pairs of cranial nerves if you are not a medical student? 6. What do the words printed in italics indicate in this exercise? 7. Is it essential for the medical student to know these uses? 8. What word indicates the number of pairs of cranial nerves? 9. Through what consonant? PROTOPLASM. Albumen, gluten, fibrin, syntonin, are closely allied substances known as proteids, and each is composed of carbon, hydrogen, oxygen and nitrogen. PROTEIDS ... Protector ... commonwealth ... for all ... _albumen_ ... all men ... liars ... fibs ... _fibrin_ ... brindled ... spotted ... sin ... _syntonin_ ... toe nails ... hoofs ... glue ... _gluten_. The foregoing exercises show that there are no facts of Science, &c., or in Daily Life, with which the System cannot cope--thus proving the greatest saver of Labour and Time if the pupil makes an application of it to his studies or business when once he has mastered the system.
