The author, after briefly noticing the results of some of his expe­riments described in two papers which appeared in the Philosophical Magazine for July and November, 1837, and also those of Mr. Ro­bert Rigg in a paper read to the Royal Society, next adverts to the theory of M. Raspail, detailed in his Tableau Synoptique , and Nouveau Système de Chimie . In opposition to some of the views entertained by the latter, he finds that in the bark of the bamboo and the epidermis of straw the silica incrusting these tissues is not crystallized, but, on the contrary, exhibits, both before and after incineration, the most beautiful and elaborate organization, consisting of an arranged series of cells and tubes, and differing m its character in different species of the same tribe, and in different parts of the same plant. The observations of Mr. Golding Bird, contained in the 14th number of the Magazine of Natural History, New Series, are then referred to; and the author states in confirmation, that, by employ­ing caustic potash, the siliceous columns may be removed from the leaf of a stalk of wheat, while the spiral vessels and ducts, which form the principal ribs of the leaf, as well as the apparently metallic cups which are arranged on its surface, remain undisturbed. He proposes, therefore, to substitute, in the description of vegetable tissues, the term skeleton , instead of that of bases , whether saline or siliceous, of those tissues.

Artistic Career

When Johann Wilhelm Theodor Ludwig von Blandowski (1822-1878), was appointed Government Zoologist on 1 March 1854, Victoria gained a scientist, who had attended Tarnowitz Mining School and science lectures at Berlin University. He had been an assistant manager in part of the Koenigsgrube coal mine at Koenigshütte, but as a consequence of some kind of misdemeanour, resigned from the Prussian Mining Service and joined the Schleswig-Holstein Army in March 1848. After resigning his Lieutenant’s commission and trying unsuccessfully to obtain another appointment in the Prussian Mining Service, he left for Adelaide in May 1849 as a collector of natural history specimens. After some collecting expeditions and earning a living as a surveyor he moved to the Victorian goldfields. He undertook official expeditions in Central Victoria, Mornington Peninsula and Western Port and in December 1856 he was leader of the Murray-Darling Expedition, but control of the Museum passed to Frederick McCoy with Blandowski relegated to the position of Museum Collector. Feted on his return from the Expedition, he fell out with some members of the Royal Society of Victoria over somewhat puerile descriptions of new species of fishes and he also refused to recognise McCoy’s jurisdiction over him. After acrimonious arguments about collections and ownership of drawings made whilst he was a government officer, Blandowski resigned and left for Germany, where he set up as a photographer in Gleiwitz in 1861, but some kind of mental instability saw him committed to the mental asylum at Bunzlau (now Boleslawiec, Poland) in September 1873, where he died on 18 December 1878. Assessments of Blandowki’s scientific and artistic career in Australia have been mixed. The biographical details presented provide the opportunity to judge assessments of Blandowski in Australia against his actions both before and after his arrival there.

The principal business of public interest which has occupied the attention of the Council relates to the extension of accurate magnetical and meteorological observations in different parts of the world. A communication having been made by Lieut. William Denison, of the Royal Engineers, of a proposal from General Mulcaster, In­spector-General of Fortifications, that the officers of engineers ge­nerally should be employed, under the direction of the Royal Society, in promoting the advancement of science, by carrying on connected series of observations relating to Natural History, Meteorology, Magnetism, and other branches of physical science, and suggesting an application to Government for a grant of funds necessary for ef­fecting so desirable an object; a Committee was appointed to con­sider of the proposed measure, and of the means of carrying into effect the recommendations contained in the letter of Baron Von Humboldt, addressed in April last to His Royal Highness the Pre­sident.

Considering the number of vertousi, who apply themselves to the collecting natural curiosities of the insect, bird, and beast kinds, it is surprizing that so few have endeavoured to discover effectual means of preserving their curiosities, when collected; one would imagine that those Gentlemen, in particular, who write on natural history, would be exceedingly desirous of such effectual methods, which, if once discovered and communicated to the public, would be the means of their receiving many rare subjects, and even non-descripts from different parts of Asia, Africa, and America, which would afford infinite pleasure to naturalists, and greatly encourage the study of natural history.

ABSTRACT: In spite of his many other interests, Edward Heron-Allen also worked for nearly 50 years as a scientist on minute shelled protists, called foraminifera, much of it in an unpaid, unofficial capacity at The Natural History Museum, London, and notably in collaboration with Arthur Earland. During this career he published more than 70 papers and obtained several fellowships, culminating in 1919 in his election to the Royal Society. Subsequently, he bequeathed his foraminiferal collections and fine library to the Museum, and both are housed today in a room named in his honour. In this paper, for the first time, an assessment of his scientific accomplishments is given, together with a full annotated bibliography of his publications held in the Heron-Allen Library. This is part of a project to produce a bibliography of his complete publications, recently initiated by the Heron-Allen Society.

Important Evidence

The deed of conveyance of 1722, by which Sir Hans Sloane gave the Society of Apothecaries control of their ‘Physick Garden at Chelsey’ in perpetuity, forged an important link between the Apothecaries and the Royal Society, one that has lasted to the present day. For the next 75 years the Apothecaries paid an annual tribute of dried plant specimens to the Royal Society as proof that they were continuing to use the garden for its proper purpose. These specimens, which have survived the centuries with remarkably little damage, now provide important evidence of what was being grown in the garden at the time and may also be nomenclaturally important as representing plants given botanical names by Philip Miller in 1768. A careful search in the herbarium collections of the Department of Botany in the Natural History Museum at South Kensington, where the Royal Society specimens are now held, has resulted in the location of all but a small number of the 3750 specimens that were sent. Tracing them has not been easy for a number of reasons, not least because they are now dispersed among the several million specimens in the Museum’s collections. The names of the plants used by the Apothecaries in the lists that were the starting point for the search were those current at the time, hence of pre-Linnaean character, and had first to be linked to present-day names before the work could begin. Some lists of names were found to be inaccurate and some were entirely misleading.

The article discusses the hitherto unknown correspondence between the Danzig (present-day Gdańsk) botanist Jacob Breyne, his son Johann Philipp Breyne, and James Petiver in the last decade of the seventeenth century. Their correspondence documents contacts between one of the most important naturalists of the Polish-Lithuanian Commonwealth in the second half of the seventeenth century and members of the Royal Society. The content of the letters reveals how books, naturalia and various artefacts circulated between Western and East-Central Europe. It also reveals the principles of reciprocity and friendship followed by those who conducted inquiries into natural history.

The eminent Georgian scientist John MacCulloch (1773—1835) is remembered today chiefly as a practical geologist but his many publications show that he also made notable contributions in such fields as chemistry, medicine and natural history; indeed his wide scientific competence seems to have been a significant factor in his election to Fellowship of the Royal Society, for it is noted on his certificate of application that he was ‘very conversant with various branches of science’. Elsewhere it is recorded that MacCulloch ‘was as willing to impart information as he was eager to acquire it’ and in this context his activities as a teacher in the East India Company’s Military Seminary at Addiscombe deserve study: first, because the later part of his life, during which he taught geology, is poorly understood; and secondly, since his last two geological books were affected by his teaching commitment at Addiscombe. In this paper MacCulloch’s connexion with the college is investigated using hitherto unpublished manuscript records and some of his geological work is re-assessed in terms of the facts revealed.

We have investigated Total Ionizing Dose (TID) effects on a 1.4μm-pitch, Deep-Trench Isolation (DTI) CMOS image sensor for its use in radiation environment. Our investigation includes characterization and TCAD simulations (with parametric modeling) of the image sensor before and after irradiation with 60Co gamma rays source for TID from 3 to 100 Krad. We have obtained agreements between measured results and simulated ones on degradations of the characteristics Quantum Efficiency (QE) and dark current (Idark). The agreements validate our modeling and simulation approach to evaluating these characteristics. It has been shown that TID causes evolution of interface states of different parts of the pixel, which are responsible for QE and Idark degradations. TID effects on different parts of the pixel can be identified and quantified.
