 analogies are with various forms of masked epilepsy though, as a race, 

 the Malays are not subjects of epilepsy, neither are they prone to 

 alcoholism. 



Insanity in (ireece. 



Dr. F. B. Sanborn, late Inspector of Health, Lunacy and Char- 

 ity of the Massachusetts Board of Health, contributes to the Journal 

 of Mental Science a suggestive article on the comparative frequency 

 of mental diseases in Greece and America. He shows tliat while the 

 population of Greece is about that of Massachusetts, the estimated 

 number of insane in the former is 2,000, while in the latter there are 

 over 7,500. The proportion of those under treatment in the two 

 countries is as i to 15. 



As one reason for this difference Dr. Sanborn assigns the much 

 less alcoholic insanity in Greece. Something must doubtless be at- 

 tributed also the less density of population and the genius (jf the race. 



While the Greeks are prone to shocking crimes there is less of 

 vice than in northern Europe or the United States. Vice is a fre- 

 quent cause of insanity. General paralysis is terribly prevalent in 

 America and is much less common in Greece. "General paralysis 

 almost always proceeds from vice and most generally from debauch." 



Colors Dependent on Food. 



E. B. Poulton, in Proceedings of the Royal Academy for June 

 8, 1893, offers facts to substantiate his theory that colors of certain 

 Lepidopterous larvae are made up of modified chlorophyll derived 

 from the food plant. Larvae from one batch of eggs of Tryphana 

 pronuba were divided into three lots fed (in darkness) throughout their 

 whole life upon (i) green leaves, (2) yellow etiolated leaves and (3) 

 white mid-ribs of cabbage. The larvK of (i) and (2) acquired their 

 normal green or brown colors as in nature, while those feed on white 

 plant tissue, containing neither chlorophyll or etiolin were unable to 

 produce the green or brown ground color, though the production of 

 dark superficial pigment was unchecked. 



Tlie Spanisli Inqnisition as an Alienist.- 



Mr. H. C. Lea presents several characteristic pictures of religious 

 monomania during the Fifteenth Century, and the action taken in the 

 matter by the church, (Popular Science Monthly, XLHI, 3.) It is a 

 question whether future generations will find our treatment of alien-
