We give, on another page of our paper, the able decision of Commissioner Holt in the extension case of Goodyear's india rubber patent. Whatever difference of opinion may exist in the minds of inventors and the public at large as to the justness of the conclusions arrived at, we think that a perusal of this document will convince all, that, Mr. Holt is not only possessed of fine abilities, but also that peculiar appreciation of the interests iiiu worth of inventors which pre-eminently fits him for the responsible office of Commissioner of Patents. Throughout the entire document there is discernable a conscientious desire to arrive at a decision compatible with the facts, and the interests and rights of all concerned, and if an error has been committed at all, it is one of jndgment and not of will. In the concluding portion, which we shall give in our next issue, the Commissioner incidentally makes a dignified and manly defense of the rights of inventors; and in dwelling upon the injuries alleged to have been sustained by Goodyear, in common with other inventors, at the early stages of the introduction of his invention, he reaches a degree of eloquence which is alike honorable to his head and heart. Our original intention was to publish this report in three or four parts, but after carefully examining it, we found that by dividing it into more than two parts its sense would be materially affected in the perusal. We think our readers will agree with us that the general interest attached to this paper fully justifies us in giving it the large space we do.
