AbstractThe functional morphology of the insect compound eye is reviewed with special reference to its surface and volume relationships with the rest of the head and its evolutionary development. Measurements of the more important parameters of the eyes of 28 species representing 14 major orders are given and interpreted in relation to this review. Recent histological and biophysical work on insect vision is also reviewed and some conclusions, especially those concerning the limit of sensitivity in the ultra-violet, are shown to be consistent with current theories of the early history of the oceans, the atmosphere, and of life.

Abstract. The paper describes the early history of EISCAT, from the very first ideas and Nordic contacts in the late 1960s to the end of the main development phase, when the facility had become a very advanced and reliable research instrument and its users had developed full competence in the second half of the 1980s. The preparation of the ''Green Book'', the Beynon meeting in London in 1973 and the activities started there, the first EISCAT Council meeting, the ''technical period'' 1976–1981, the inauguration in 1981 and the decade of improvements in most of the 1980s are described as seen from the Swedish point of view.

The vast number and variety of sequences, those liturgical interpolations which in the middle ages commonly followed the repetition of the Alleluia in the Mass, and the freedom of their development, show that they were an outlet for the creative talents of musicians and poets. A sample of sequences from successive periods allows the literary historian to trace the development of rhyme and accentual meter, and a musicologist has described the sequence ‘as the parent of oratorio and the grandparent of modern drama.’ But while a view which encompasses centuries reveals to us variety and change, the compositions of any given time were largely shaped by inherited traditions. Not the least value of studies on the early history of the sequence is their demonstration of the close connection between various Alleluia melodies and their sequences and the way in which appropriate texts were fitted to melodies for specific feasts.

By 1940, a half dozen or so commercial or home-built transmission electron microscopes were in use for studies of the ultrastructure of matter. These operated at 30-60 kV and most pioneering microscopists were preoccupied with their search for electron transparent substrates to support dispersions of particulates or bacteria for TEM examination and did not contemplate studies of bulk materials. Metallurgist H. Mahl and other physical scientists, accustomed to examining etched, deformed or machined specimens by reflected light in the optical microscope, were also highly motivated to capitalize on the superior resolution of the electron microscope. Mahl originated several methods of preparing thin oxide or lacquer impressions of surfaces that were transparent in his 50 kV TEM. The utility of replication was recognized immediately and many variations on the theme, including two-step negative-positive replicas, soon appeared. Intense development of replica techniques slowed after 1955 but important advances still occur. The availability of 100 kV instruments, advent of thin film methods for metals and ceramics and microtoming of thin sections for biological specimens largely eliminated any need to resort to replicas.
