EXEMPTION FROM PUBLIC DUTIES
The existence of certain diseases may be claimed as a bar to active service, both in a civil and in a military capacity; and the opinion of a medical man may be required as to the fitness or unfitness of the individual for the service from which he claims exemption. In giving certificates of this nature, the medical practitioner cannot be too guarded in wording them; and each case must be treated on its merits, so that strict justice may be done.
Among the diseases which may incapacitate a man for active employment may be mentioned—syphilis; hernia; phthisis; affections of the eyes, attended with dimness of vision, or colour blindness; varicose veins; and some other diseases.
