In his admirable essay on the Devonian Fishes, in the Tenth Decade of the Geological Survey, Professor Huxley has clearly indicated and described the differences and the resemblances of the genera Holoptychius and Glyptolepis. In the interesting work of the Rev. Dr. Anderson on ‘Dura Den,’ in which its exquisitely-preserved fossils are described, no mention is made of Glyptolepis. In the November part of the ‘Journal of the Geological Society of London,’ Mr. Powrie lias called attention to the occurrence of Glyptolepis in slabs recently disinterred, for the St. Andrew's Museum, from Dura Den. Through the kindness of Dr. Anderson, a slab was presented to the Montrose Museum in 1859; and it is now apparent from it that Glyptolepis is not of rare occurrence at Dura Den, and that either this genus has been passed over altogether, or confounded with Holoptychius. The fishes in the Montrose Museum are smaller, and do not in all points correspond with those described by Mr. Powrie, but we think they emphatically demonstrate that the Holoptychius Flemingii must now be denominated Glyptolepis.On the slab in the Montrose Museum there is one fine specimen of Holoptychius and six specimens of Glyptolepis, not regarding fragmentary portions of fishes. At the first glance there is a resemblance in size, in general aspect, and outline, among the fishes. Their average length is about nine inches, and their breadth at the thickest part of the body nearly three inches.

AbstractKoran manuscripts that fit comfortably within the palm of one’s hand are known as early as the 10th century CE.For the sake of convenience, all dates will be given in the common era (CE) without further mention, and not in the Islamic or Hijra calendar. Their minute and sometimes barely legible script is clearly not intended for comfortable reading. Instead, recent scholarship suggests that the manuscripts were designed to be worn on the body like pendants or fastened to military flag poles. This is corroborated by some preserved cases for these books which feature lugs to attach a cord or chain, but also their rare occurrence in contemporary textual sources. While pendant Korans in rectangular codex form exist, the majority were produced as codices in the shape of an octagonal prism, and others as scrolls that could be rolled up into a cylindrical form. Both resemble the shapes of similarly dated and pre-Islamic amulets or amulet cases. Building on recent scholarship, I will argue in this article that miniature or pendant Koran manuscripts were produced in similar forms and sizes because of comparable modes of usage, but not necessarily by a deliberate imitation of their amuletic ‘predecessors’. The manuscripts’ main functions did not require them to be read or even opened; some of their cases were in fact riveted shut. Accordingly, the haptic feedback they gave to their owners when they carried or touched them was not one of regular books but one of solid objects (like amulets) or even jewellery, which then reinforced this practice.

Geology is a science which owes, not only its inception, but its continued existence largely to its non-professional disciples and lovers. In fact, of the two classes existing at the present time, the ‘amateur’ and the ‘professional,’ it would by no means be difficult to show that the former gave birth to. the latter, and that some of the best living professional geologists have been recruited from the ranks of the amateur class. To a small band of early amateurs we are indebted for the foundation alike of the Geological Society and the Geological Survey in this country.

ABSTRACTSeasonal fluctuations in oestrous activity and live weight were studied in ewes of the Marwari breed indigenous to the Rajasthan Desert in north-western India. Of the ewes examined 80 to 100% were in oestrus every month of the year, indicating thereby the non-seasonality of female reproductive activity in this breed. On average, each ewe exhibited heat 18 times a year. The incidence of silent heats was low (4·2 %). The average length of an oestrous cycle was 17 days, while the actual period of oestrus varied from 24 to 48 h with an average of 36 h. No seasonal effect on these activities could be observed. The maximum and minimum body weights of the animals were recorded during the autumn (October) and summer (June) months respectively. The body weights differed significantly (P<0·05) between months. Sexual activity in these animals is, therefore, apparently not affected by changes in body weight. The continuous nature of oestrous activity in Marwari sheep may be economically exploited by regulating the lambing season according o t the prevailing ecological conditions and market demands, without the use of hormones.

When I sent the above paper to the Geological Magazine, I was not aware that a Sketch of the Geology of the Isle of Man, by Mr. John Home, F.G.S., of the Geological Survey of Scotland, had been published in the Transactions of the Edinburgh Geological Society.

Dr Hope in the first place read, from the Proceedings of the Geological Society in London, the account of the freezing cavern furnished by the President of the Geological Society of London. This is one of several caves which exist in the southern face of a lengthened low hillock of gypsum. It is entered from the south by a passage rather narrow, and is about fifteen feet high, ten paces long, and seven wide, which seemed to send off irregular fissures into the body of the rock.


During the interval which has elapsed since the subject-matter of this paper was presented in lecture form, a memoir has been completed by the Cenozoic Research Laboratory of the Geological Survey of China, on the subject of “ Fossil Man in China ” and ancillary problems of Cenozoic research in that area (Black and others, 1933). By reason of this fortunate circumstance it has become possible to incorporate in the present communication a resume of the chief geological, palaeontological, and archaeological conclusions to which we have been led as a result of the completion to its present stage of that wider study. It is a pleasure to acknowledge here my indebtedness to my friends and colleagues of the staff of the Cenozoic Research Laboratory, without whose cordial co-operation and assistance the present paper could not have been written. To my friends Dr. V. K. Ting, Honorary Director of Cenozoic Research in China, and Dr. Wong Wen Hao, Director of the Geological Survey of China, I wish also to express again my most hearty thanks for their unfailing help and support throughout the whole course of my work in China. I wish further to thank Dr. Wong for permission to use here, in modified form, a number of illustrations which have appeared earlier in publications either of the Geological Survey, or of the Geological Society, of China. The general physiography and location of the Choukoutien area is admirably illustrated in Professor G. B. Barbour’s two block diagrams, figs. 1 and 2, and in the three field sketches by the same artist of the immediate Choukoutien terrain, here reproduced in fig. 3. I am much indebted to Professor Barbour for his kindness in preparing and permitting me to use these instructive and artistic illustrations.

Background: The sternum is one of the skeleton parts with frequently detected variation in cross-sectional images or autopsy series. The anatomical or congenital variations of the sternum in the anterior chest wall may involve malignancies, injuries or severe traumas. The aim of the study was undertaken to evaluate the incidence of anatomical and congenital variations of human dry sternum bones.Methods: This study was carried out on 120 dry human sternum bones irrespective of age and sex at Varun Arjun medical college- Banthra, UP, KMCT Medical College, Manassery-Calicut and Melaka Manipal Medical College-Manipal. All the sternum bones were macroscopically inspected for the anatomical and congenital variations of human dry sternum bones. Photographs of the anatomical and congenital variations were taken for proper documentation.Results: Complete sternal foramina in the body of the sternum were noted in 9 bones (7.5%), with an average vertical diameter of 17mm and transverse diameter of 16mm (The highest vertical diameter of 19mm and transverse diameter of 17mm was noted); Incomplete sternal foramina in the body of the sternum were noted in 4 bones (3.3%);Complete sternal foramina in the xiphoid process of the sternum were noted in 7 bones (5.8%) with an average vertical diameter of 6mm and transverse diameter of 8mm; Unusual complete sternal foramina in the body and incomplete sternal foramina in the xiphoid process of the sternum were noted in 8 bones (6.6%); Very rare longer xiphoid process (7.3 cm) with complete sternal foramina was noted in 7 bone (5.8%); Unusual Longer xiphoid process with an average length of 6.7cm with sharp bifid ends was noted in 8 bones (6.6%).Conclusions: The knowledge of existence of anatomical variants and congenital foramina of sternum and xiphoid process found in our study is essential, especially for bone marrow sampling, radiology (X - ray, CT, MRI, and USG) reporting, pathology autopsy and forensic medicine post-mortem reporting and patoacupuncture practice to avoid complications during various surgical procedures.
