312 PRACTICE OF PHYSIC. 



ease, although affecting different parts, is always of the same na- 

 ture and proceeds from the same cause. Very commonly indeed 

 those different parts are affected at the same time ; and there- 

 fore there can be little room for the distinction mentioned. 



The disease has been frequently treated of under the title of 

 Tussis, or Cough ; and a cough, ; indeed, always attends the chief 

 form of catarrh, that is, the increased excretion from the bron- 

 chise : But a cough is so often a symptom of many other affec- 

 tions which are very different from one another, that it is impro- 

 perly employed as a generic title. 



MXLVII. The remote cause of catarrh is most commonly 

 cold applied to the body. This application of cold producing 

 catarrh can in many cases be distinctly observed ; and I be- 

 lieve it would always be so, were men acquainted with, and at- 

 tentive to, the circumstances which determine cold to act upon 

 the body. (See XCIV. XCVI.) 



From the same paragraphs, we may learft what, in some per- 

 sons, gives a predisposition to catarrh.

 ally begins with some difficulty of breathing through the nose, 

 and with a sense of some fulness stopping up that passage. This 

 is also often attended with some dull pain, and a sense of weight 

 in the forehead, as well as some stiffness in the motion of the 

 eyes. These feelings, sometimes at their first beginning, and 

 always soon after, are attended with the distillation from the 

 nose and sometimes from the eyes, of a thin fluid, which is often 

 found to be somewhat acrid, both by its taste, and by its fretting 

 the parts over which it passes. 



MXLIX. These symptoms constitute the coryza and gra- 

 vedo of medical authors, and are commonly attended with a sense 

 of lassitude over the whole body. Sometimes cold shiverings 

 are felt, at least the body is more sensible than usual to the cold- 

 ness of the air ; and with all this, the pulse becomes, especially 

 in the evenings, more frequent than ordinary. 



ML. These symptoms seldom continue long before they are 

 accompanied with some hoarseness, and a sense of roughness and 

 soreness in the trachea, and with some difficulty of breathing, 

 attributed to a sense of straitness of the chest, and attended with 

 a cough, which seems to arise from some irritation felt at the
