NEW YORK, SATURDAY, DECEMBER 28, 1867. * * * * * THE LAST NUMBER OF VOLUME XVII. We give in this number a full index of the volume of which this is the last issue. No doubt this will be more satisfactory to our readers--those at least who preserve their numbers for binding, and probably most do--than publishing the index in a separate sheet. The list of claims in this number will be found to be unusually full, a gratifying evidence that dullness of business does not cripple the resources nor abate the industry of our inventors. With a parting word of good will to our present subscribers and a welcome to those who begin with our new volume, we wish for all a HAPPY NEW YEAR. * * * * * COMMENCEMENT OF A NEW VOLUME.
