We have node the various disease* of the skin the 

 fourth order of the Paratrepse*. an arrangement which 

 we are induced to adopt, because we regard then as, 

 for the moat part, proceeding from, or depending upon, 

 s morbid condition of the body, connected with a de- 

 fect of tone of the function* either directly or indirect- 

 ly concerned in the process of nutrition. Some of them 

 are. no doubt, entirely local in their origin, and remain 

 so daring the whole of their progress ; IMU in the ge- 

 I view which we ar* now taking- of the subject, it 

 not be practicable to attend to these n>

 as are constitutional, and such as are local. The first 

 of them come on suddenly, and produce some distur- 

 bance of the functions, and after running through a re- 

 gular course, manifest a tendency to a spontaneous cure ; 

 the second come on gradually, continue tor an indefi- 

 nite length of time, disappear, and again make their ap- 

 pearance in an irregular manner, and this without nc- 

 ily producing any constitutional action, or being

 In the 3d place, some cutaneous daws**)* are obviously 

 hereditary, the children of those who have been affect- 

 ed by them having a peculiar tendency to such affec- 

 tion*. In the 4th place, different cutaneou* dUeaaes 

 are observed to attach themselves especially to different 

 period* of lite, tome being confined to childhood, other* 

 appearing more commonly about the period of puberty,

 contrary, there are other* which require only constitu-
