List of Patents for new Inventions. 75

 the steam -boat now plying between London and Margate, and 

 of which a drawing was given in a previous number, was planned 

 by Mr. Robertson Buchanan. This is a mistake — that gentle- 

 man had no concern in planning that vessel, having merely se- 

 lected the drawings of it as best calculated to illustrate his valu- 

 able paper on steam-boats given as above.
