gradually in the exact ratio required. In the course of the day 

 the building was moved about ] 6 feet, without the least detri- 

 ment or jar ; the other five feet will be finished this morning. 

 There was so little danger manifest, that during the time the 

 house was moving, the owner entertained about 150 persons 

 within it with a handsome collation ! ! The expense of removing 

 the building is about one fifth of its value, and there is no 

 doubt that this plan will in future, in many instances, be 

 adopted, and a great portion of the expense of pulling down 



and rebuilding be saved. 



Obituary. — Lately, at Magdeburg, died the celebrated M. 

 Carnot, aged 70. Political events brought him to take a lead- 

 ing part in the affairs of liis country; but it is our province to 

 notice him as a man of science only, in which character he was 

 distinguished by his great attainments in the higher branches 

 of the mathematics. A translation of his Reflections on the 

 Theory of the Infinitesimal Calculus is printed in our 8th and 

 9th volumes ; and his Essay upon Machines in general in our 

 30th volume, accompanied by a portrait of the author.
