Holidays in Paris.
--Our French neighbors across the water have not the horror of fairs which is the fashion in this country. Thursday, the 24th inst, was the last day of the Ham Fair, which is held in the middle of Paris, lasts several days, is a source of much edification to the flaneurs, and, we hope, a great economy to the good housewives; on Easter Sunday comes the turn of the children--fifteen days of gingerbread fair ! What a prospect for mothers, children, and doctors!
