SUBJECT INDEX 



(alphabetical order) 



Although the Index is intended to be self-explanatory, some introductory 

 remarks may be useful. 



The Index is composed of headings (large capitals) and entries (small print 

 and small capitals). In general, an attempt has been made to start the entries 

 with the most informative word, but it was impossible to avoid that entries 

 sometimes start with an adjective of a rather unspecific character, such as: 

 comparative, descriptive, experimental; abnormal, normal; early, late. Such 

 entries are easily overlooked in a search for specific information, particularly 

 in the longer sections. 



Since virtually all the material in this index refers to developmental processes, 

 the word "development" is usually omitted from the entries (not from the 

 headings). Words like "differentiation", "egg", "embryo" etc. are usually 

 retained. The more or less synonymous phrases "action of/on-", "effect of/ 

 on-", and "influence of/on-" are all retained in the entries. Other frequently 

 occurring phrases are "role in/of-" and "relation to/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, research subjects have been brought under as 

 many headings as possible (e.g. under a discipline, an organ, a technique, and 

 a substance) . This of course leads to a certain amount of redundant informa- 

 tion, but it is felt that this is outweighed by the greater chance for the user of 

 finding a particular subject he is interested in. 



For various reasons it is impossible 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", "Embryology", "Life Cycles", "Metamorphosis", "Morpho- 

 genesis", "Regeneration", "Reproduction", etc. Genus and species names are 

 not used in the entries, with the exception of the designation Homo for the 

 human species. 



All the work on plants {including cellular slime molds etc.) is brought to- 

 gether under one heading: "Plant embryology & morphogenesis (experimental 

 & physiological)". 



In the case of work carried out jointly by two or more investigators, all 

 collaborators are listed in alphabetical order. Since initials of 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.
