In the year 1888 I published a short paper in the pages of the Geological Magazine and in “Nature,” in which I gave a brief account of the discovery of the fauna of the Olenellus (or Lower Cambrian) zone in the Comley or Hollybush Sandstone of Shropshire. Since that date great advances have been made in our knowledge of the Olenellus fauna of other areas, and the Olenellus zone has now generally attained an established rank and systematic position in the Geological Record as the basal zone of the Cambrian system.

This short paper examines the origins and nature of the reflective writing that is presently required on one part-taught doctorate in education (EdD) programme. It explores the various ways in which EdD candidates have engaged with self-reflection, using a number of extracts from writing submitted for formal assessments (including of the doctoral thesis itself, the culmination of their doctoral journey). The specific ways in which individuals have been caused to interrogate their place within, and contributions to, their respective professional realms are examined, as is the question of how writing in reflective vein has contributed to the evolution of professional identity. In the context of reflective writing, particular attention is paid to the ways in which the specific matter of developing confidence with accessing and manipulating language is frequently cited by individuals. As appropriate, connections are made in the paper between the above dimensions of what I am terming pensive professionalism and the perspectives of certain writers. The article concludes by drawing attention to the ways in which those of us involved in delivering professional doctorates need to be aware of, and induct our candidates into, the benefits of pensive professionalism.

This section, which was completed last year, appears of such value and interest to students of the Tertiary strata of the London Basin, that I have thought it worth while to offer a description of it to the readers of the Geological Magazine. Through the courtesy of Dr. Barton, the Governor of the Asylum, I have had free access to the specimens preserved of the various strata passed through, and very careful use of them has been made in the preparation of the tabulated statement which follows; much of the information having been kindly furnished from the engineers who were employed. The Asylum is situated at Knap Hill, about a mile and a quarter from Brookwood Station on the South-Western Eailway, and is on the Upper Bagshot Sands. The mouth of the well is in the valley just below, about 140 feet above O. D., and about the same level as that at which the Middle Bagshot Beds occur in the famous Goldsworthy section, which furnished Prof. Prestwich, some forty years ago, with the clue to the succession of the beds of the Bagshot Formation. It is about a mile and a half distant therefrom. The evidence as to the horizon in the Bagshot Series, at which the well commences, is very clear to those who are familiar with the stratigraphy. The widely-extended pebble-bed at the base of the Upper Bagshot Sands occurs here very near the top of the well, and I saw it exposed again at about the same level in an excavation made by the side of the high road which runs along the western side of the Asylum Estate. The same greenish loamy sand was intermingled with the pebbles in both cases. In the ploughed field a stiff yellow loam, such as so commonly occurs above this pebble-bed in the Bagshot area, crops out in the valley where the well is situated. The ‘brown sandy bed’ which occurs at the top of the section is probably a portion of this, re-constructed by later drift action, and mingled with more sandy materials washed down from the sandy strata situated at higher levels on the slopes of the valley.

Disklike, firm, bilaterally symmetrical fossils recovered from the middle Lower Cambrian Amouslek Formation of the Moroccan Anti-Atlas are described under the name Microschedia amphitrite n. gen. and sp. Their systematic affinity, particularly to brachiopods and cnidarians, and resemblance to existing taxa are discussed. Although interpretation as a brachiopod appears to be more convincing, their morphology does not permit a precise determination of systematic position.

From time to time I have received from correspondents suggestions that the method of determining the geological age of the Earth by the rate of solvent denudation of sodium might be open to considerable error if the allowance made in my paper (Trans. R.D.S., ser. ii, vol. vii), for sodium chloride carried from the sea by winds and washed from the atmosphere by rain, was seriously at fault. These suggestions arise from incomplete study of the quantities involved. Had more space been given in my paper to this question, the hasty criticisms I have had to contend with, doubtless, would be less often advanced. The whole matter is capable of the simplest arithmetical statement, and the limit of error arising from this source easily defined. Recently one gentleman has written at considerable length on the matter in the pages of the Chemical News. I have replied to Mr. Ackroyd in that journal. But the definition of the limit of error referred to, and the consideration of some other points raised in the discussion, are more in place in a geological than in a chemical journal. I would therefore seek for space in the Geological Magazine wherein to repeat in part what I have said in the Chemical News, adding some matters more especially suited to geological readers.

A number of communications dealing with the origin and composition of the material commonly known as laterite have appeared in the Geological Magazine during the past few years. That of Dr. Maclaren is an especially valuable contribution to the literature of the subject, and I think few workers in the Tropics will be disposed to question the substantial accuracy of his conclusions. I shall not attempt, therefore, to discuss the general problem presented by the widespread occurrence of laterite deposits in tropical regions. The object of the present brief communication is merely to place on record a few observations made in another area.

In the Palæontology of the Vertebrata, so much progress is made in various directions in Britain, that it seems advisable to attempt to bring up to date the record of the subject prepared and published by the writers a year ago. The following list may thus be regarded as the first supplement to the work in question; and it is hoped, by the courtesy of the Editor, to issue such a list of additions annually in the GEOLOGICAL MAGAZINE.

With more than 1,000 species in some 70 genera, Lejeuneaceae represent the largest family of liverworts. Although much progress has been made in recent years, the supraspecific classification of Lejeuneaceae has not yet been satisfactorily solved. Maximum likelihood and Bayesian analyses of a three marker dataset (nrITS, cp DNA rbcL and trnL-trnF) derived from 85 accessions of Lejeuneeae and 13 outgroup species revealed Pictolejeunea picta in a sister relationship to the remainder of Lejeuneeae, the most speciose tribe of Lejeuneaceae. Based on the outcome of the phylogenetic analyses, we establish subtribe Pictolejeuneinae subtr. nov.

Do So

In submitting the following short paper, I do so clearly realizing that deductions from limited observations present many sources of fallacy; also that even extended observations made in a limited area are very liable to error, and need correction by extended observation; that peculiarities of race, and circumstances connected with locality may even in such a matter as this exercise a marked influence. I trust, however, to hear the experience of others on the subject.

The Family

In a short paper on the nomenclature of the Old Red Sandstone Fishes published in this Magazine for November, 1888, I expressed the opinion “that the scattered teeth and fragments of jaws known as Dendrodus and Lamnodus belong to fishes at present known to us by their scales as species of Holoptychius and Glyptolepis.” The family terms “Holoptychiidæ” and “Dendrodontidæ” I consider absolutely synonymous. On the other hand, the Rhizodontidæ (Gyroptychius, Tristichopterus, Rhizodus, etc.) present a somewhat different form of tooth-structure, and one which is, in the main, identical with that which, in so many Stegocephalous Amphibia, is called “labyrinthodont.”

The oldest rocks of the Holy Cross Mountains, Poland – biostratigraphy of the Cambrian Czarna Shale Formation in the vicinity of Kotuszów

AbstractThree lower Cambrian acritarch assemblages recognized in four outcrops in the vicinity of Kotuszów in the southernmost part of the Palaeozoic inlier of the Holy Cross Mountains span a stratigraphic interval from the uppermost part of the Asteridium tornatum-Comasphaeridium velvetum Assemblage Zone to the Skiagia ornata- Fimbriaglomerella membranacea Assemblage Zone (most probably its lower part). According to current views (Moczydłowska and Yin 2012), this interval corresponds to the upper part of the Fortunian and to Stage 2 of the Terreneuvian Series. The strata yielding the oldest assemblage are thus the oldest precisely documented rocks in the Palaeozoic succession of the Holy Cross Mountains, and the oldest Cambrian rocks exposed on the surface in Poland. The current biostratigraphic scheme for the pre-trilobitic part of the Cambrian System in the Holy Cross Mountains should be modified so that it is based on local acritarch interval subzones.
