Sentence:  "My dear fellow, I know you well. I know the <WSD>military</WSD> neatness which characterises you. You shave every morning, and in this season you shave by the sunlight; but since your shaving is less and less complete as we get farther back on the left side, until it becomes positively slovenly as we get round the angle of the jaw, it is surely very clear that that side is less illuminated than the other. I could not imagine a man of your habits looking at himself in an equal light and being satisfied with such a result." 
Meaning of the word marked with <WSD> tags:  Characteristic of members of the armed forces.
