junior a n d senior students in t h e p r e p a r a tion a n d proper presentation of laboratory results. T h e author has presented his ideas in a formal report, showing o n e a c ceptable style. Modification* of this basic style m a y b e required by t h e plans of any particular instructor. Considerable emphasis is laid on " T h e Chemical Literature," which is a necessary p h a s e of any research report b u t may not b e always requisite to a good laboratory report. I n summary, this book can b e considered satisfactorily to introduce t h e user to t h e formal report style, and, as such, is a good addition to t h e chemical engineer's library-.
