driving off the spleen and regulating the circulation. Whenever I

find myself growing grim about the mouth; whenever it is a damp,

drizzly November in my soul; whenever I find myself involuntarily

pausing before coffin warehouses, and bringing up the rear of every

funeral I meet; and especially whenever my hypos get such an upper

|
hand of me, that it requires a strong moral principle to prevent me
|
|
from deliberately stepping into the street, and methodically knocking
|
|
people's hats off--then, I account it high time to get to sea as soon

as I can. This is my substitute for pistol and ball. With a

philosophical flourish Cato throws himself upon his sword; I quietly
