mention eye strain, which is chiefly muscular in origin. The 
muscles which move the eyeballs, and the muscles which contract 
the pupils, and increase the convexity of the lens are all liable 
to the same exhaustion as other muscles. We have only to 
remember the Academy headache to realise how severe may be 
this form of fatigue. This fatigue is what is called Asthenopia. 
Rest temporarily relieves it. Many workmen who have to use 
their eyes for fine work see much better at the beginning of the 
week after the Sunday rest, but in the middle of the week the 
signs of Asthenopia recur, and cause obscurity of vision with 
frontal and occipital headaches. 
The question of training is too great to enter into to-night, 
but I would say in passing, it has a real power in delaying fatigue, 
and sparing the organism from its dangerous influence. ‘The 
improvement of the digestion, of the circulation, and the action 
of the skin assists in rapidly eliminating fatigue products. The 
question of dress, too, is of no less importance. During cold 
weather, especially if in a cold east wind, there is a real danger of 
having 400 “2¢//e clothing, permitting too rapid loss of heat, and so 
quickening the onset of fatigue. In very hot weather it goes 
without saying all clothing should be light and loose, and not in 
any way interfering with muscular contraction. 
BRAIN FATIGUE. 
By this I mean exhaustion of the Intellectual faculties, and 
the other special functions of the Brain, and, considering the 
conditions of life at the present time, I am sure you will agree 
with me that no subject could be of greater importance tous. I 
am not going to speak as a pessimist and long for the good old 
times. Personally I feel no time in the world’s history has been 
better than the present. The chances of the child developing 
into youth and manhood, and the man living on to middle life, 
and even old age, are much greater to-day than they have ever 
been before. But the twentieth century has its own special 
dangers, and probably the greatest of these is fatigue, and 
especially 4vaiz and merve exhaustion. The colon Bacillus and 
Cocci are hunted to the death by the Medical Officer and his 
Sanitary staff in Brighton; and I am paying a deservedly high 
compliment to the efficiency of their work when I tell you that, 
as far as zymotic diseases are concerned, Brighton compares most 
favourably with any large town in the Universe. Our lungs and 
stomachs are guarded most vigilantly by Dr. Newsholme ; but I 
wish the law would empower him to look to the state of Brighton’s 
brain and nerves. Many diseases have been all but banished, but 
_I fear nerve diseases are on the increase I make this suggestion 
in no frivolous spirit, Something will have to be done soon, and
