NAUTICAL INVENTION. 



A gentleman has lately invented a very simple and i»g«- 

 nious method by which a v,essel without any person on board 

 can be directed with very considerable accuracy in a given 

 course. The application of this invention to fire-ships 

 would be of vast utility: and that this may be judged of wrth-

 means by which it is effected, the model used in the first 

 experiments, which we understand were completely satisfac- 

 tory, may be seen at Mr. Thomas Jones's, mathematical, 

 optical, and philosophical instrument maker. No, 124,
