236 Dr. F. W. Mott. Haamination of Nervous [Oct. 22, 
glands there was nothing noteworthy in the appearance of the organs and 
tissues. The brain was quite normal in appearance, and there was no excess 
of fluid. 
It may be mentioned that this man contracted syphilis on July 27, 1906, 
and he was treated for some time with mercury, and a note on February 15, 
1908, is as follows:—Condition the same as August 6, 1907, but no 
trypanosomes found in blood or glands, due to fact of taking mercury for 
syphilis. 
Histological Examination.—Sections were prepared of portions of the 
cerebrum, cerebellum and medulla oblongata, by all the methods which 
I have previously adopted for the examination of the tissues of Sleeping 
Sickness cases. I found no trace of the characteristic meningeal and 
perivascular infiltration, nor of gliosis. Sections of the spleen, liver, and 
kidney were also examined with negative results. 
I have shown that there is a parallelism between the intensity of the 
signs and symptoms of Sleeping Sickness and the diffuseness and intensity 
of the lymphatic perivascular infiltration with lymphocytes and plasma cells 
which is the main cause of the clinical phenomena. 
It may be asserted that this case proves that human trypanosomiasis 
is curable, but it does not prove that Sleeping Sickness is curable, for I 
contend that the diagnosis of “ Sleeping Sickness” can only be made when 
there is proof that the trypanosomes have invaded the sub-arachnoid space. 
The case emphasises the importance of early diagnosis of the infection and 
the value of early energetic treatment by organic arsenic preparations. How 
far the administration of mercury assisted to complete the cure is uncertain.
