If there be any among my Readers who, having turned over the pages of "Enquire Within," have hastily pronounced them to be confused and ill-arranged, let them at once refer to The Index, at page 389, and for ever hold their peace.<br><br>The Index is, to the vast congregation of useful hints and receipts that fill the pages of this volume, what the Directory is to the great aggregation of houses and people in London.<br><br>No one, being a stranger to London, would run about asking for "Mr. Smith." But, remembering the Christian name and the profession of the individual wanted, he would turn to the Directory, and trace him out.<br><br>Like a house, every paragraph in "Enquire Within" has its number, - and the Index is the Directory which will explain what Facts, Hints, and Instructions inhabit that number.<br><br>For, if it be not a misnomer, we are prompted to say that "Enquire Within" is peopled with hundreds of ladies and gentlemen, who have approved of the plan of the work, and contributed something to its store of useful information. There they are, waiting to be questioned, and ready to reply. Within each page some one lives to answer for the correctness of the information imparted, just as certainly as where, in the window of a dwelling, you see a paper directing you to "Enquire Within," some one is there to answer you.<br><br>Housekeepers of experience live at Nos. 1, 30, 438, 1251 and 2091; old Dr. Kitchiner lives at 44; Captain Crawley is to be found at 46 and 2568; the well-known Mrs. Warren lives at 1809; Miss Acton at 1310; Dr. Franklin at 1398; Mrs. Hitching at 215; Mr. Banting at 1768; Dr. Wilson Philip at 1762; Mr. Withering at 2338; Mr. Mechi at 997; Dr. Stenhouse at 1776; Dr. Erasmus Wilson at 1700; Dr. Southwood Smith at 1743; Dr. Blair at 2180; M.
