operations upon Africa are proceeding. The agents will push south- 

 ward from Tunis even to Timbuctoo and Soudan. Xative agents will 

 be trained to circulate the Scriptures, and at the same time to sub- 

 serve the purposes of honest trade. The agents will be at once mis- 

 sionaries and examples of conversion able to face the climate, able 

 to converse on a level with those whom they propose to influence ; 

 and it is probable that by these simple means a species of black 

 brotherhood will be extended through the continent, directly conduc- 

 ive to the spread of religion, incidentally, of constructing a machinery 

 tor the spread of civilization, of commerce, and of civilized transit. 



It is proposed to open in London a " College of Domestic Economy," 

 where every thing necessary to a perfect knowledge of the culinary 

 art and other domestic matters will here be taught by a person of 

 great experience and acknowledged ability. The students for practice 

 will be divided into classes of four or five each, with a servant stu- 

 dent to attend on each class, and assist them in their operations. 

 Each class will provide what may be required for their practice, to 

 be arranged by the student managing the class for the week, and the 

 articles prepared will be consumed for their meals. 



An excellent plan for promoting the social and sanitary condition 

 of the working-classes in England, has been set on foot in the forma- 

 tion of museums for the exhibition of all objects bearing upon physical 

 comfort and domestic economy, from the construction of dwelling- 

 houses down to the minutest details of their furnishing. A society 

 for this object also exists in Paris, under the name of the Societe 

 cPEconomie Charitable. These museums will contain specimens of 

 thfi most approved and cheapest kinds of furniture, household utensils, 

 clothing, fuel, and other stores, besides models and plans of the ex- 

 ternal and internal arrangements of buildings of every description, 

 workshops as well as dwelling-houses. 



A valuable and interesting acquisition has recently been made by 

 the Arundel Society of England, which furnishes the means of ex- 

 tending its agency to the illustration of a new class of artistic monu- 

 ments. Three gentlemen, who have devoted much time to the study 

 of mediaeval art, have, with the permission of the owners, or guardians, 

 of some of the principal private and public collections in England and 

 on the Continent, made impressions, in gutta-percha, from several of 

 the finest of the ancient ivory-carvings in their possession ; and by 

 employing these impressions as matrices, from which models or types 

 for molding are produced, casts in what is termed "fictile ivory" have 

 been subsequently manufactured, which preserve, to a great extent, 

 the beauty of the originals. Duplicates of .these casts have been 

 placed on sale at a low rate by the officers of the Society. They are 

 divided into classes, so as to exemplify, as far as possible, the charac-
