Under the head of Patents we have to announce to our 

 readers that Mr. Leger Didot (not Roger, as mentioned by mis- 

 take, in the list of new patents contained in our last number) 

 has just completed the specification of his patent for improve- 

 ments upon the machines already in use, for making wove and 

 laid paper, in continued lengths, or separate sheets ; and we do 

 it the more especially, as from the great length of the specifica- 

 tion, and the extensive drawings necessary to elucidate it, there 

 seems little probability of its being made public in any other 

 way. In the improved machines the ordinary paper moulds can 

 be carried forwards in an endless succession, and paper made 

 upon them in sheets, with the usual wire marks, just the same as 

 by hand, or it may be made of any required length, and without 

 the marks. The same machine will also make paper upon an 

 endless revolving wire web, as in a former patent machine of the 



same artist.
