title: INOCULATION AGAINST TYPHOID IN MARYLAND.
abstract: We can scarcely understand why certain sections of the lay mind still look with horror upon inoculation, in spite of the many proofs of its efficacy. This excellent paper, in which is discussed the attack-rate among inoculated persons, adds to the proof, if proof be needed, a convincing argument.
