points mentioned with cases from his own ex- 

 perience. The article is to be continued in 

 the next issue. Dr. Ward A. Holden presents 

 some statistics on the early ocular signs of 

 dementia paralytica, and sums up as follows : 

 " In true, uncomplicated paresis there is early 

 in the disease almost constant absence of the 

 sensory reflex, in half the cases irregularity of 

 the pupils, in nearly half inequality of the 

 pupils, in more than half abnormally small 

 pupils, in a fifth of the cases loss of light re- 

 action, in another fifth marked sluggishness 

 of light reaction, and in a few of those with 

 diminished light reaction a diminution of con- 

 vergence reaction also. A preliminary paper 

 on psychasthenia, its clinical entity illustrated 

 by a case, is contributed by Sidney Schwab."
