As the next number ofthe Scientific Ame-ricarl will be the last one of this volume, we hope our readers will renew their subscriptions at as early a date as possible. If they could all do so next week, along with many new subscribers, we would be able to form a very good estimate of the number of papers which we would have to print in opening Volume Nine, in order that we might be able to supply every subscriber with the volume. Our next number will contain a complete index of this volume, and a beautiful title page, engraved expressly for the Scientific American, which cost $250. We are much obliged to a great number of our subscribers, who have already, within the pasb week,promptly renewed their subscriptions. Our friends will confer a favor upon us if they will show their prospectuses and the chapter ot suggestions on other pages, to their friends who are not subscribers. We honestly believe that no mechanic or manufacturer can invest two dollars to better advantage than in subscribing for the Scientific American.
