Mr. Witty, by a judicious attention to proportions, and the conveniences required, has succeeded in adapting the original invention of Watt (described under the word Furnace,) to domestic stoves, particularly those of the close kind. Mr. Witty has, however, unadvisedly taken out a patent for these stoves, although we can discover nothing that is original in the principle nor in the arrangement of the parts. Some elegant and very effective stoves on this plan may be seen at the Museum of National Manufactures and the Mechanic Arts, in Leicester-square.
