Camphor in large doses causes disorder of the mental facul-

differs from the latter in more frequently causing delirium and 
convulsions. Epilepsy also has been ascribed to the use of

: Camphor has peculiar antaphrodisiacal properties, the smell 
of it often producing this effect. ‘Camphora per nares castrat

prescribed it either mixed with other medicines, or to be taken 
at the same time with them; and, what is worse, during the 
perturbation of morbid symptoms. For what Alexander has 
observed of its pure effects amounts to = and = been 
expressed only in general terms. 
“The action of Camphor is perplexing and difficult to study, 
even in a healthy subject, because the primitive effects often 
alternate rapidly with vital reaction, so that in many cases it is 
hard to distinguish between the primary and consecutive effects. 
“Camphor is not less puzzling and surprising as regards the 
results of its action, for it destroys the violent effects of a great . 
many different vegetable remedies, as well as those of cantha- . 
rides, and a variety of mineral and metallic substances. It must, ao 
therefore, exert a kind of general pathological action, to which .
