When any sign of deviation other than normal development of speech is detected in a child the cause of such deviation should be at once investigated. Categorically this cause of speech difficulty is due to either hard of hearing or mental defficiency. Gesell's test of speech development combined with hearing test for infants appeared to he highly satisf-actory in determining the cause of speech retardation.
