43. Canal Steam JVavigation. — With a view to the in- 

 troduction of steam vessels on canals, a very interesting ex- 

 periment was made in the Union Canal at Edinburgh, on 

 June 22, at 2 o'clock, with a large boat twenty-eight feet 

 long, constructed with an internal movement upon the prin- 

 ciple of a model invented by Mr. Wight, and exhibited to 

 a general meeting of the Highland Society of Scotland in 

 the month of January last. A committee appointed for the 

 purpose by the Directors of the Highland Society attended 

 to witness the experiment, and the chairman and most of 

 tl)e members of the Union Canal company were also pre- 

 sent. The boat had twenty-six persons on board; and al- 

 though drawingfifteen inches of water, she was propelled by 

 men at the rate of between four and five miles an hour, 

 while the agitation of the water^ being confined entirely to 

 the centre of the canal, was observed to subside long before 

 it reached the banks, and consequently obviating its hidier- 

 to destructive tendency in washing them into the canal.

44. Mr. Brongniarts JSotice of American Specimens of 

 Organized Rernarns. — A letter froni Mr. Alexander Brong- 

 niart to the Editor, dated May 23d, 1822, expresses great 

 interest in, and gratification from, the various specimens of 

 American organized remains which he had received, espe- 

 cially from those forivarded through the Editor, from Mr. 

 E. Hitchcock of Massachusetts, Mr. E. Granger of Zanes- 

 ville Ohio, Mn Z. Cist of Wilkesbarre, and Mr. G. T. 

 Bowen of Providence. Should the friends of Geology con- 

 tinue (which it is earnestly hoped they will,) to furnish sim- 

 ilar specimens to Mr. Brongniart he will soon be in a condi- 

 tion to draw those general conclusions respecting the Amer- 

 ican formations by means of which they can be successfully 

 compared with those of the Eastern Continent.
