HEADACII. 547 



less vertigo added to these symptoms. The ears are also affect- 

 ed, as they have a sensation of various noises, as of storms of 

 wind, rushing of waters, a symptom which is termed tinnitus 

 aurium. Oftentimes too the smell and taste are affected, and al- 

 most destroyed. But we must observe, that, instead of these 

 symptoms, there is frequently an increase of sensibility, so that 

 the smallest light, or gentlest noise, disturbs the patient. The 

 internal senses are also affected, the memory is impaired, the 

 imagination incoherent, and, from a want of attention, the judg- 

 ment is disturbed. Sometimes the headach produces a deliquiuni 

 animi, though not very frequently. It often is attended with 

 bilious vomitings, and commonly with a costive belly, and pale- 

 ness of urine. After all these have continued for some time, a 

 stupor and sleep come on, which terminate the fit. 



" As to the state of the pulse, oftentimes, even in violent and 

 long-continued headachs, it is not sensibly altered from its ordi- 

 nary state. In other cases it is altered, and very variously, 

 becoming not uncommonly less frequent than before. In other 

 cases it is not changed in its frequency, but becomes fuller dur- 

 ing the paroxysm, especially in the parts affected, whence arises 

 the throbbing and perceptible pulsation, accompanying this dis- 

 order. But sometimes this fulness is also accompanied with an 

 increase of frequency. 



" We mentioned that the connexion between the different 

 states of the temperature of the parts and the state of the pulse 

 is very decernible. Thus, where there is a sense of cold with 

 a pale skin, the pulse is either less frequent, or, at least, is not 

 increased in that respect. Where there is a heat in the part, 

 frequently accompanied with swelling and with more or less 

 redness, the pulse is more full and frequent. 



" We have now spoken of the form of the disease, and shall 

 only add a few general remarks upon its recurrence. The par- 

 oxysms vary in the degrees of violence, duration, and period. 

 They come on at different times of the day; as, in some, on. 

 waking in the morning ; in others, at noon or soon after meals ; 

 frequently in the evening ; and in some persons, after going to 

 bed, and towards midnight. They differ also greatly in their 

 duration, continuing for some hours, sometimes for days. They 

 have almost always a remission, and return at certain inter-
