While a few parasitic copepods have been described from the fishes of Ceylon by Wilson (1906) as well as by Kirtisinghe (1932-37) and some recorded from the fishes of Bombay by Bassett-Smith (1898) only three parasites belonging to the family Lernacopodidae are described by Thompson and Scott (1902), all from Ceylon. However, Lernaeopodids occurring elsewhere have been exhaustively treated by Kroyer, Brian, Scott, Wilson, Gurney and Leigh-Sharpe. The sub-family Clavellinae in particular has not been recorded from India, and as Clavellisa dussumieriae, a new species treated in this paper, exhibits certain features of general interest, a full description of both the female and the male was deemed fit.

The attachment of sedentary marine organisms is not only of general interest to the biologist but is of very great economic importance because of the fouling of ships' bottoms and other submerged surfaces. Our knowledge of the season of attachment and growth of marine fouling organisms in various harbors is not extensive, especially for the west coast of America. Coe ('32) and Coe and Allen ('37) studied the season of attachment and growth of sedentary organisms at La Jolla, California where open coastal conditions prevail. Johnson and Miller ('35) investigated fouling in Puget Sound. Kofoid and Miller ('27) reported on the marine borers of San Francisco Bay. However, there is very little information available regarding the season of settling of the true fouling organisms of San Francisco Bay. It is the purpose of this paper to present the results of studies made with test panels set out over a period of more than a year in Oakland Estuary at Oakland, California. The writers wish to acknowledge their indebtedness to Dr. Lucile Mason for identification of algae; to Dr. Olga Hartmann for identification of Annelids; to Mr. C. R. Shoemaker for identification of amphipods; to Mr. J. 0. Maloney for identification of isopods; and to Miss Elizabeth Loudon and Miss Mary North for technical assistance.

As an extension of the eddy current pattern computed by Koefoed and Kegge (1968) for a thin vertical infinitely-conducting half-plate in presence of oscillating magnetic dipoles, this paper computes the contribution to the (electro-) magnetic anomaly at the receiver by each element of the vein separately. Twelve contour diagrams for such elemental contributions are presented as samples. Two points of general interest stand out: (1) The contributions from different portions of the vein are not all of one sign; the contribution from one part may cancel that from another; and (2) The portion of the vein nearest to the transmitter-receiver system does not necessarily make the largest contribution to the total measured signal.

This paper describes and examines three particular features of the official national income tables recently published by the Fiji Government. The need of development planners for a comprehensive set of national accounts incorporating detailed information relating to central government current expenditure, the operations of the private business sector, and the rural household economy has assumed special importance. The uses and limitations to the information contained under these specific headings is discussed and throughout an emphasis is placed on the need for the adoption of consistent and systematic methods of collection and estimation procedures to facilitate planning and decision making. As aids to more detailed interpretation and analysis, the features described are considered to be of general interest to other developing countries.

The. East Bay Water Company supplies water to Oakland and Berkeley, California, and other adjoining muncipalities on the east side of Saa Francisco bay.4 The average daily consumption of water for last year was 32 million gallons, approximately two-thirds of which was filtered water from surface sources. There are two major filtration plants, the San Pablo plant located just north of Berkeley and the Upper San Leandro plant 15 miles to the southeast in Oakland. These plants have been described in engineering literature, (1) (2), and therefore this paper will be confined to a discussion of certain operating experiences which it is believed should be of general interest. Only the briefest reference to design features, essential to elucidation of operating problems, will be made.

I have three concurrent concerns in this paper. The first is to display a picturable model of some of the main features of phenomenological method. I wish in this case to clarify some of the complexities and implications of a phenomenological procedure for a philosophical context often more Anglophilic and Europophobic than not. But on the way to this end I wish also to begin the sketch of what I hope will become a considered re-interpretation of phenomenological history. I wish to differentiate two distinguishable, but often confused, lines of development from a common base in Husserlian thought.

This paper contains the text of a briefing on a method of estimating spare-part “essentiality” or “shortage penalties.” The estimates are made by collecting and combining the judgments of individual maintenance specialists. While the talk was primarily directed to a military audience, the subject appears to be of general interest, since the problem of estimating shortage penalties must be faced in applying any of the optimal inventory policies which have been developed in recent years. The quantitative solution of many other management problems also requires input data which can only be obtained on the basis of expert judgment.

Together with a number of collaborators I have made a detailed investigation of the differentiation of the flora and the distribution areas in one of the Aegean regions, the Cyclades. In this paper a few points of general interest concerning the phytogeography of this region are discussed, e.g. the „natural” vegetation, the distribution of rock plants, the explanation of the „Cycladian gap” in the distribution of some species.

Recent research in gerontology has included refined measurements of physiologic variables reflecting changes in the central nervous system in aging. Most such measurements are accurate and of general interest; however, they are of relatively little use to the clinician in his evaluation of the aged patient, because of the elaborate equipment required. Standard reference works in medicine offer little help to the physician who attempts to evaluate the neurologic status of his aged patient. Information to be presented in this paper is based on data gathered from routine neurologic examination which has not involved the use of complicated electrical or mechanical equipment.

The Lewis base behaviour of B6H10 is reported with a number of Lewis acids including BC!3, BBr3, 813, AiR3 (R Me, Et, i-Bu), B3H7, B4H8, B8H12, and i-B9H1 .Anew preparation of B6H9Br is reported as well as the new compounds B6H9l, B6H8Br1, B6H812 and related species with CH3 as well as halogen. Structures have been redetermined for a number of boron hydrides. The asymmetric location of the unique bridging proton in B5H11 has been established. The structures of SiH3 and CH3 pentaboranes have been determined by electron diffraction for both the 1 and 2 substituted isomers. Significant bond shortening occurs for SiH3 in the I position. The intent of this paper is to present an overview of progress in the study of the simple hydrides of boron since the first meeting at Prague in 1971. Since most of the active workers concerned with this chemistry are present at the meeting, relatively little time will be devoted to the discussion of results from other laboratories. Certain high spots deserve mention but a number of interesting recent developments will be presented by their originators later in this meeting. I shall concentrate largely on structural and synthetic studies carried out at Indiana University. Threee advances in the chemistry of the boranes deserve special mention. Hermanek reported in 1972 that the partial hydrolysis of 61120 led to the formation of the previously unknown 4H. In a second particularly interesting development Davison and co-workers reported in 1972 the synthesis of the .t-Fe(CO)4—B6H10 molecule1. The consequences of this observation are developed more fully below. Finally, Professor Davison has kindly allowed me to quote some recent results from his laboratory that I believe to be of considerable significance and general interest. Briefly, he has been able to produce decaborane in 10-10 per cent yield by reaction of silver fluoroborate or silver nitrate with the lithium salt of pentaborane-9. Further development of this reaction could have exciting implications on the economics of decaborane synthesis.
