As also are defective hearing, or speech; persons blind in one eye; one-armed, one-handed, or one-legged persons, or those having crippled arms or legs, or those suffering from asthma or hernia. Deaf mutes and persons with defective speech may, however, be appointed to the positions of mail clerk, distributor, and directing and forwarding clerk.
