In order to reduce the cost of printing as well as the size of the volumes, smaller type has been used for the Directory of Names and Addresses and for the Directory of Institutes. India and the U.S.S.R. show a considerable increase in the numbers of institutes listed. Contact was again established with Uruguay. Information concerning the Hubrecht Laboratory may be found on page 263. For information regarding the "International Institute of Embryology" (in- cluding the latest membership list), please see page 264. This section also gives details concerning the Vlth International Congress of Embryology (topic: "Nucleocytoplasmic interactions during differentiation") (Paris, 1 — 7 Sept. 1968). P. D. NIEUWKOOP J.

Within each of these categories an alphabetical order is maintained. An index to continents and subcontinents follows below: Africa P- 167 N. America Canada P- 168 United States P- 169 Centr. America P- 180 S. America P- 180 Asia P- 180 Australia Australia P- 185 New Zealand P- 185 Europe P- 185 The Directory does not give Institute addresses. These can be found by looking up the name of one of the Institute members in the Directory of Names and Addresses. Names of Institute members who are not explicity engaged in developmental biology are as a rule not listed, with the exception of the names of Institute directors. (*) Asterisks indicate those Institute members who appear in the Directory of Names and Addresses with one or more subjects. If all members of an Institute lack asterisks, this usually means that no information has been sub- mitted by the Institute in 1967. Older information concerning such Institutes may be found in previous issues. AFRICA EGYPT Alexandria, Alexandria Univ., Fac. of Med., Dept. of Anat. MINA, E. Y. Asst.

The Index covers not only embryology, but the whole of developmental biology. It is composed of headings (large capitals) and entries (small print and small capitals). The names printed in small capitals refer to the Directory of Names, where the corresponding research subjects may be found. The headings generally come under one of the following categories: 1 ) dis- ciplines, 2) techniques, 3) cells, organs and other body components, 4) sub- stances or classes of substances, 5) developmental stages, processes or factors. Since virtually all the entries in the Index refer to developmental processes, the word ''development" is omitted unless used in a general sense. In general, an attempt has been made to start the entries with the most informative word, but is was impossible to avoid that entries sometimes start with an adjective of a rather unspecific character, such as: comparative, descriptive, experimen- tal; abnormal, normal; early, late. Such entries are easily overlooked in a search for specific information, particularly in the longer sections. Entries also fre- quently start with such phrases as "role in/of" and "relation with". Prepositions very seldom figure as the first word of an entry (except in the phrase "in vitro"); where they do, they are found at their proper place in the alphabet. In order to increase the efficiency of the Index, special care has been devoted to cross-references. Moreover, subjects have been brought under as many headings as possible. This of course results in a certain amount of redundant information, but it is felt that this is outweighed by the greater chance for the user of finding a particular subject he is interested in. All the work on multicellular plants and on slime molds is brought together under one heading: "Plant Embryology 6 Morphogenesis (experimental & physiological)". All the work on unicellular organisms (including unicellular plants) is listed under the heading "Unicellular Organisms". Genus and species names are not used in the entries, with the exception of the designation Homo for the human species. For various reasons it is im.possible to provide a separate taxonomic index. Those who are looking for work on a specific taxonomic group are advised to start with the headings of a general nature, such as "Asexual reproduction", "Development", "Em- bryology", "Life cycles", "Metamorphosis", "Morphogenesis", "Plant em- bryology & morphogenesis". "Regeneration", "Reproduction", "Unicellular organisms", etc. In the case of work carried out jointly by two or more investigators, all collaborators are listed in alphabetical order. Since initials o[ first names are omitted from the entries, it may sometimes be necessary to check two or more investigators of the same surname in the Directory of Names. 203 ABDOMINAL CAVITY see Body cavities ABNORMALITIES see Anomalies (early development); Malformations sec also Teratogenesis ACCESSORY SEX GLANDS sec Reproductive system ACTIN see Muscle(s) ACTINOMYCIN see also Antibiotics effect on development, Diptera BELLONI effect on develop:!ient 6 regeneration.
