A friend of mine*, in discoursing with me lately on phvsio- 

 logical subjects, mentioned the occurrence of increased irrita- 

 bility in persons at certain periods, in such a manner as would 

 lead one to suspect that there were general and periodical causes 

 of disorder, which more or less affected most people. I have 

 frequently noticed this circumstance myself, and believe it to be 

 the consequence of a state of the atmosphere, the peculiarities 

 of which are at present little known. The particular kind and 

 arrangement of the clouds seem to me to be one indication of 

 this state of the air. As I have before discoursed largely on this 

 circumstance, I need only recall the attention of your readers to 

 the subject ; as it is only by a multiplicity of observations that 

 any thing certain in natural philosophy and physiology can be 

 determined.
