There is an increasing need today for hooks, films,and manuals to help train paraprofessionals in many technical fields. One of these fields is that of the laboratory technician. It was disappointing to find that this hook does not fill the need. It contains too many explanations and examples that are so abbreviated as to he either wrong or confusing. For example, in explaining how to shift a decimal point to arrive a t an equivalent exponential notation there appears (On p. 4)
An experienced teacher can see through this. A beginning student would he pueeled. On page 15 an example is given of raising a. number to a power by multiplying its logarithm by the power and finding the antilogarithm. The written example is 4 3 = log (4.5)' = 3 X log 4.5 = 91.1 Again an experienced teacher can interpret this. Can a student? The same type of inequality is used to explain how to obtain roots by logrtrithms. The reviewer groped for reasons to explain some of the deficiencies in this hook, which claim to review techniques and apply them to the solution of practical problems in chemical or health science lahartttories. A clue might be found in Chapter 2, Logarithms. On page 11 one finds "the logarithm tahle (in the sp~ e n d i x )has a set of proportional parts to assist you in interpolation between the last two digits." The four place logarithm tahle does not have any such set. On page 12 the text refers to "the tahle of antilogarithms." There is no such tahle. Without it, the explanation that follows is meaningless. These omissions, the use of numbers without dimensions, i.e., "lo-'" for hydrogen ion concentration of neutral water instead of "10-7 moles/l," typographical errors, and too many illogicsl sequences lead one to suspect that the hook was put together in a great hurry and therefore suffered from poor editing and poor proofreading. With due concern for the correction of these flaws, a second edition could be much more valuable. Lest the above comments seem overly critical, several additional examples s u p port the suspicion. On page 46, under molar solution cdaulations, one reads "when working with molar solutions if you first determine the quantity of solution in a liter, it is then easy to calculate (Continued on page AS@)
