degrees, and thus we see that however potentially tempera- 

 ment predisposes to diseases, its potentiality will vary with 

 the individual. Whilst the temperaments are thus generally 

 "mixed," it will usually be found that one especially prevails, 

 and may be thus said to characterise the individual. The 

 modifying influences of the temperaments in disease may 

 be thus briefly stated. The sanguine temperament predis- 

 poses to disease characterised by the rapidity of the 

 inflammatory process, and predisposes its possessors to acute 

 affections which develop themselves regularly and completely,, 

 defervesce rapidly, and generally with well-marked symptoms 

 of crisis. Such persons are especially liable to plethora, 

 congestions, inflammations, haemorrhages of an active charac- 

 ter, gout, and inflammatory fever. The nervous temperament 

 predisposes to disorders of the nervous system, convulsive 

 diseases, various congestions and haemorrhages, hepatic and 

 internal obstructions, neuralgia, insanity, and melancholia. 

 The diseases to which the lymphatic temperament predis- 

 poses are generally of a chronic character, and of an 

 asthenic type, as debility, tuberculosis, scrofula, and dropsy;, 

 and the temperament itself is usually associated with an 

 inferior power of resistance to attacks of acute disease, and 

 is characterised by adynamia or slowness of the nervous 

 and circulatory systems, and by retardation or deficiency of 

 the general assimilative functions. The bilious temperament 

 tends to dyspeptic affections, hypochondriasis, and hepatic 

 derangements generally. It should, however, be remembered 

 that however highly we may estimate the influence of tem- 

 peraments in predisposing to disease, they themselves are 

 capable of being altered in character by age, habit, and 

 external circumstances, and by the physical and mental 

 changes originating in disease or accident. The tempera-
