MEDICAL INSPECTION OF SCHOOLS 



by a normal eye. From top to bottom, the lines on the card 

 are numbered respectively 50, 40, 30 and 20. At a distance 

 of 20 feet the average normal eye should read the letters on the 

 20 foot line, and if this is done correctly, or with a mistake of 

 one or two letters, the vision may be noted as f, or normal. 

 In this fraction the numerator is the distance in feet at which 

 the letters are read, and the denominator is the number over 

 the smallest line of letters read. If the smallest letters which 

 can be read are on the 30 foot line, the vision will be noted as 

 f; if the letters on the 40 foot line are the smallest that can be 

 read, the record will be f; if the letters on the 50 foot line 

 are the smallest that can be read, the record will be . 



If the child cannot see the largest letters, the 50 foot 

 line, have him approach slowly until a distance is found where 

 they can be seen. If 5 feet is the greatest distance at which 

 they can be read, the record will be & (^ of normal). 



Test the second eye, the first being covered with the 

 card, and note the result, as before. With the second eye 

 have the child read the letters from right to left, to avoid 

 memorizing. To prevent reading from memory, a hole i^ 

 inches square may be cut in a piece of cardboard, which may 

 be held against the test letters, so as to show only one letter at 

 a time, and may be moved about so as to show the letters in ir- 

 regular order. A mistake of two letters on the 20 or the 30 foot 

 lines, and of one letter on the 40 or 50 foot lines, may be allowed, i 



Whenever it is found that the child has less than normal 

 sight, f, in either eye, that the eyes or eyelids are habitually 

 red and inflamed, or that there is a complaint of pain in the 

 eyes or head after reading, the teacher will send a notice to\ 

 the parent or guardian of the child, as required by law, that 

 the child's eyes need medical attention. 



METHOD OF TESTING HEARING 



If it is possible, one person should make the examina- 

 tions for an entire school, in order to insure an even method. 

 The person selected should be one possessed of normal hearing, 

 and preferably one who is acquainted with all the children, the 

 announcement of an examination often tending to inspire fear. 

 The examinations should be conducted in a room not 

 less than 25 or 30 feet long, and situated in as quiet a place as 

 possible. The floor should be marked off with parallel lines
