By a man's finger-nails, by his coat-sleeve, by his boots, by his trouser knees, by the callosities of his forefinger and thumb, by his expression, by his shirt cuffs -- by each of these things a man's calling is plainly revealed. That all united should fail to enlighten the competent inquirer in any case is almost inconceivable.  -   Arthur Doyle     Quotes
