Since publishing an engraving and description of this wheel, we have received testimony 1 from certain reliable parties setting forth its good qualities. From the high source from ?which the recommendation comes, we feel confidence in commending the Baldwin wheel to any who may desire an economical water power. Mr. Baldwin's advertisement may be found on another page. REMOVALS.—We understand that Commissioner Holt has made several removals in the Patent Office during the past week. Prominent among those who have been ousted we may name Professor Schaeffer, Chief-Examiner in the Chemical Department. UP to the time of going to press we have been unable to procure a copy of the new Patent Bill. It is believed to contain very objec- 1 tionable features, therefore we are anxious to ( get hold of it.
