Research today is progressing so rapidly in a variety of distinct disciplines that it is difficult to correlate the findings in these many fields into a coordinated body of knowledge. This series strives to emphasize the unity of cytology. We have continued our general policy of publishing criticaal reviews of subjects which are included within the term cytology. Where it is possible to publish in the same volume two or three papers in the same field this has been done, but for obvious reasons it is not always feasible to do so. It is gratifying to note that the International Review of Cytology has become increasingly international. Included in this volume are five contributions from the United States, four from Great Britain, one from Brazil, one from Japan, one from India, one from France, and one from Sweden. The subjects dealt with also extend over a wide range-to name but a few, there are studies of bacterial structure, histochemistry with labeled antibodies, spermatogenesis,
