significance for the understanding of mental 

 behavior. Both in its supports and in its con- 

 flicts the subconscious discloses the intimate 

 sources of mental life. It must not be thought 

 of as an independent or mysterious agency a 

 subconscious self that is a double of the self we 

 know but as an integral phase of the unified 

 self that we recognize as the individual charac- 

 ter. The abnormal cases, it is true, suggest 

 independence and division; but the theory of 

 dissociation establishes the gradual links from 

 normal to abnormal that make clear that one 

 relation is responsible for the whole series. 

 Many points remain obscure, and the tempta- 

 tion to fly to extreme hypotheses is strong. It 

 is part of the success of modern psychology to 

 have rescued the realm of the subconscious 

 from confused and superstitious views and to 

 have brought it in line with the central facts 

 of human nature. j.j.

 out liquefying it. Sublimation differs from dis- 

 tillation in the changing of the vapor to a solid 

 without the intervening liquid state. The prod- 

 uct is known as a sublimate. Sublimation is 

 used for purifying substances. In changing the 

 substance to vapor the impurities are left be- 

 hind and the pure substance is obtained. The 

 flowers of sulphur, that is, the common sulphur 

 of commerce, afford one of the best examples 

 of a substance obtained by sublimation. The 

 flowers of benzoin and salammoniac are made 

 by this process. See DISTILLATION. 



SUBMARINE, submareen', a vessel which 

 travels under water, but whose only practical 

 use thus far in its history has been as a weapon 

 of destruction. It ranks with the flying ma- 

 chine, a useful development of the arts of peace,
