number, twenty-five times; the least, twice; on the average, eleven 
times. 
(c) Racing in the open air: The least performance two and a half min- 
utes ; the highest, twenty minutes ; on the average, about ten minutes. 
Thus, a boy of fourteen years, weighing 88} kg.; 1.43 m. tall, with a 
width of the breast of 67 ecm., having practiced gymnastic exercise for five 
years and a half, performs climb-drawing on the horizontal bar only six 
simes and a half, bowing of the arms in-lying leaned on the parallel bars 
sleven times, and racing in the open air only ten minutes. 
This is hardly the measure in capability of performance which I have 
attained under most unfavorable gymnastic circumstances with, on the 
average, younger boys (hearing) in the school in Biitow. 
A third fixation of similar kind I made especially for this essay with 
thirty-one active members of the “ Friedrich ” gymnastic club. The num- 
ber is composed of the smallest and tallest, of the youngest and eldest 
members, as well as of those who in age and height are between those. 
Therefore this measurement. even in this small number, is of some value. 
SUMMARIES. 
(1) The deaf-mute child has many important bodily defects which 
endanger his life and his later capability to earn his bread. 
(2) To adjust this, or partly to prevent it, one has to begin as early as 
possible the physical education of the deaf-mute child in family and school, 
and to carry it through systematically over the school time. 
(3) The most excellent means for the physical education of deaf-mutes 
are exercise in cral language and physical gymnastics. To the latter, as 
the most perfect system of education for the human body, one ought to 
give the suitable time and position in the plan of education of the deaf- 
mutes.
