    Scientific diving, which was started in 1780 in the Gulf of Naples, has been developed into an important technique for obtaining new knowledge in marine biology. Some 2000 people are presently engaged in scientific diving; their work is more valuable than that of mechanical scraping and dredging. Four different stages of development are discussed on the basis of numerous citations. There are no difficulties under favourable conditions and with good technical equipment; without this, diving is still a dangerous and useless endeavour. The aim is to obtain coordinated information in the fields of ecology, behaviour of submarine organisms, geology, geomorphology and microclimatology. Moreover, the relationships depending upon the place and connecting the place with the organism must be explored first by diving, and then they can be tested by experiments. A survey of the different working places is given, and diving equipments and their necessary technical improvements for the future are described. As the direct exploration of the littoral is still somewhat in the pioneering stage — though the volume of our detailed knowledge has been significantly increased by diving — the founding of working bases, field stations, etc., is suggested. It is also proposed that governments give natural protection to the as yet untouched littoral districts by making some areas inaccessible to traffic, industry, tourism, and all other use except that of scientific research. It would be one of the most noble tasks of European States to secure some well chosen square miles of their littoral in order to promote science and to be respectful towards that part of nature where the cradle of life was on our globe. The possibility of submarine photos taken by the diver employing a T. V. device fixed on a steerable carriage, and by a diving chamber, are mentioned. The principal aim is to observe and secure information. The scientific diver will help to render the automatic mechanism more efficient to develop the photo and data processing stations, so that in the future these apparatuses can work satisfactorily and quite independent of the diver.
