means, that I might carefully examine its influ- 

 ence and the sensations which accompany it. 

 From observation and experience, and from a 

 knowledge of those measures and remedies which 

 are found beneficial in its treatment, I do not 

 hesitate to affirm, that there is, in every stage of 

 nausea, an increased quantity of blood in the chest , 

 and a diminution in the head ; but whether the 

 symptom be present because the head has lost 

 or the chest acquired, it is difficult to say. At 

 this period the face and extremities have less 

 blood than in the state of health ; the tempera- 

 ture of the body k also diminished, because the 

 increased quantity of blood in the chest lessens the 

 capabilities of the lungs to produce the ordinary 

 effects upon it, in accordance with the principles of 

 the first chapter. 



CCCXLIX. Regarding the proximate cause 

 of nausea as depending upon, or accompanied by, 

 an increased quantity of blood in the lungs or tho- 

 racic viscera, when suffering from sea-sickness, I 

 took a small portion of brandy, for the purpose of 

 exciting the internal organs, thereby enabling 

 them to regulate the unequal distribution of 

 blood. A few minutes after its exhibition the 

 various symptoms disappeared, and I felt per- 

 fectly well ; but, in half an hour, the disagreeable 

 sensation returned ; but, by a single repetition of 

 the same stimulus, the healthy conditions of the 

 system were permanently established.
