The particle atlas, edition two, volume 2, the light microscopy atlas
172 kind some errors must arise and the general impression is one of authoritative explanations made by scientists of distinction to create a book of undoubted value. D. D.
The Particle Atlas, Edition Two, Volume 2, The Light Microscopy Atlas, by Waiter C. McCrone and John Gustav Delly, Ann Arbor Science Publishers Inc., Ann Arbor, Michigan, 1973, pp. 267, price ;631.25. This volume continues the series begun with the edition on principles and techniques. Others will be appearing so in order that the reader may more fully appreciate the monumental effort involved it should be noted that the total number of volumes will be four and the cost will be k88.00. The quality of the production is maintained in this volume. The editors point out that although almost any particle can be identified by the techniques covered in Volume 1, the basis of any study must be light microscopy and in particular the polarizing microscope. This is the subject material of this volume. It is divided into four parts, the first dealing with procedures for studying samples, the second a short section deals with the organisation of the photomicrograph atlas. A third section also short deals with the use of the Atlas. These two short sections are very important and need detailed consideration. The section on the organisation emphasizes the importance of pollution by dividing the subject into, A, Wind Erosion particles, B, Industrial Dusts, and C, Combustion Products. This represents the arrangement of the Atlas section. In all the Atlas contains 609 photos. As the authors point out just as the ordinary individual can identify objects such as bananas, the trained microscopist can identify single particies of coal, cement, gypsum etc. when the microscope magnifies them to an equivalent size. The procedures for mounting materiaIs are outlined in detail. The end section here dealing with the identifying characteristics of a number of particles should prove extremely valuable. The list of references at the end of this part should prove helpful. Reading this volume reveals the nature of many of these particles. The list of wind blown particles, industrial dusts, combustion products and other miscellaneous particles shows that the source is biological, mineral, inorganic and organic. Typical industrial sources are fertilizers, cements, catalysts and foods. AU are covered adequately in this volume. This review must close with a note on the splendid quality of the illustrations in the atlas section. The text alongside each illustration is pertinent. It is hoped that the colour completes the description to enable identification to be made. D. D.
