On the cover of Musgrove's book some one has written. "A book of great interest and still greater importance to the general public." It is generally known that the neurasthenic delights to search through medical works for opinions as to his condition. It was to such a one that a physician once said, "Be careful, or you will die of a misprint." A considerable literature of perhaps a hundred volumes, adapted supposedly for neurasthenics, has been issued recently by various publishers. Of this type is the book by Musgrove. It is written in primer style, adapting a somewhat didactic tone, the aim being apparently to aid the man on the brink to keep from falling over. Opinions differ as to whether or not the man confronted by nervous breakdown is really helped by such literature. Of its type the book is probably better than most.
