A Paris letter ot July 5th, says: A complete revolution is about taking place in the manufacture of gloves. Two inhabitants of Grenoble invented about the same time a machine for sewing gloves, but instead of competing with each other,they agreed to unite the advantages of each invention. One found means to sew mechanically the fingers ot gloves, while the other, after sewing the remainder of the glove, was compelled to employ operatives to se w the fingerg. The inventors, by combining the two machines, have produced one which sews gloves perfectly. This discovery has produced a great sensation at Grenoble, where the manufacturers were not able to supply the demand for want of a sufficient number of operatives.— [Ex. [Our American Sewing Machines can sew gloves as well as other articles.
