. This small volume contains what remains of the course in Algebra, after mtltricuIntion, to t,hc stutlents in the Colleges of Civil Engineering, Mines, and Nechallic Arts in the University of California. It is intended as a, contiiuntion of the excellent work on algebra by Nr. John 3. Clarlre, of the Mathematical Department of the University and it is thought it will, in connection with Clarkes Algebra, or with any mork of similar cope, furnish a good and suficient preparatioil for those who intend to pursue tho higher mathematics. The constant aim and endeavor throughout has been so to present the various topics discussed ns to render then1 easy of comprehension by the undergraduate student. ARTICLE .
