The be view of inorganic microchemistry is contiguous with the previous review (160) and extends through December 1965. Because many techniques such as chromatography, ion exchange, extraction, nucleonics, spectroscopy, and microscopy, which are of importance in inorganic microchemistry, are reviewed as separate topics, only brief mention will be made of them in this discussion and the reader is referred to the accompanying specialized reviews for more complete orientation.It is obvious from the previous reviews of inorganic microchemistry that no real distinction is made between trace analysis and microchemistry, although many specialists feel that there is a great difference between these fields. This reviewer feels that the problems of trace studies and microanalysis are often so
