by taking care that they shall be kept as dry as possible, and that a proper degree of warmth and air shall be admitted into every chamber.  When required, M. Bonneau sends his men to clean furniture at persons’ houses, which would be rather incommodious to remove.  When any article is sent to him, the bearer is informed what day it will be completed, and is sure not to be deceived, and he has an apartment so arranged for preserving whatever is confided to him, from any injury which might be caused by moths or other insects.

Amongst those articles for which France used to depend upon England, but wherein the case is reversed by England taking from France, is that of pencil-cases, in which small pieces of lead are inserted, and emitted or withdrawn at pleasure; numbers of these formerly were sent from London and Birmingham to Paris, but recently M. Riottot has invented and obtained a patent for a pencil-case which has a little elastic tube of tempered steel placed at the end which is used, and into which the lead is inserted, and tightly held within it, so that there is no risk of breaking, either in the act of fixing in the lead, or from its afterwards shaking, the steel tube operating as a spring, retains it so firmly that it remains, even whilst writing with it, perfectly immoveable; these are arranged in gold or silver cases, more or less ornamental as may be required, and are found so infinitely more serviceable than those on the former principle, that as they are becoming more known in England, the demand for them continues to increase.  The term by which they are designated, is Porte Crayon a Pince elastique; their advantages are such as tend to economy, as they are neither liable to fall out nor break, besides the convenience of their never moving about whilst one is using them, to which the previous system was constantly liable.  M. Riottot has also an assortment of pens and pen-holders, either plated or of silver or gold, richly chased or simple, with a variety of seals and other articles; he likewise retains a stock of lead, properly prepared for inserting into the pencil-cases.  His address is at No. 27, Rue Phelippeaux, Passage de la Marmite, Escalier A, completely in the quarter of Paris inhabited by the operatives, surrounded by workshops of different descriptions, not exactly calculated for very delicate ladies.

For the benefit of a little purer air, we will quit the working mechanics’ rendez-vous, and take a lounge in the Palais-Royal, and as soon as we breathe a little freely, we will examine the engraved seals of M. Leteurtre-Maurisset, No. 33, Galerie d’Orleans, which, from the extreme delicacy of the execution, are objects well worth attention; his talents in this department have obtained him the distinction of being engraver to the Chamber of Deputies and to the royal museums; some of his specimens of armorial bearings, his designs for stamping impressions, in relief and heraldric devices, are extremely clever; he engraves
