ABSTRACT Here I rescue from obscurity a mid-twentieth-century sequence of ten paintings representing biotas and ecosystems present in different periods of geologic time. They were used to illustrate a 1955 book titled The History of Life on Earth by University of Vienna paleontologist Erich Thenius. The paintings were also mass produced as classroom teaching aids in the form of wall chart roll-ups. Thenius collaborated with Viennese landscape artist Fritz Zerritsch to produce these scenes from Deep Time. In terms of the selection and arrangement of animals in some of the scenes, Thenius and Zerritsch were probably influenced by well-known paleoartists Rudolph Zallinger and Charles R. Knight. I corresponded with Professor Thenius concerning his collaboration with Zerritsch, and his answers to my questions illuminate some of the choices he made. The Zerritsch/Thenius collection of paleo-scenes is a good example of the pageant-of-life-through-time genre of paleontological art. I use this sequence of prehistoric tableaux to examine artistic conventions within this genre.

Needs Analysis in the context of language-learning-teaching is an important process to design a certain course and syllabus. It helps course designers to set objectives, choose content, method of instruction, appropriate teaching aids, and classroom activities for different courses. This paper reports the perceptions of the researchers on the English language learning needs of the English undergraduate students of Shaheed Benazir Bhutto University Sheringal, Pakistan. The data is based on the researchers’ personal experience and first-hand observation of the population as the researchers have been teaching in the target context for about a decade. Furthermore, the researchers have always been in discussion with their students and colleagues about the target students’ English learning needs, preferred learning styles, motivation in learning English, interest, strengths/weaknesses, and attitude toward English learning in the target setting. Learners’ assignments, exam answer sheets, and presentations have also been used is a source of data collection. A needs analysis model proposed by Hutchinson and Waters (1987) has been applied in order to analyze the data. The results show that the students lack well grammatical sentences, have poor spellings, capitalization problems, limited vocabulary, unaware of collocations, poor/slow reading comprehension, and lack of effective presentation skills. Furthermore, most of the students have a lack of involvement in classroom activities and feel shy about speaking the English language. It was reported that the provision of authentic material, interesting activities, suitable audio-visual aids, relevant texts, language labs, and other logistic arrangements can better help them in learning the English language. The findings demonstrate that the students wished to have a learner-centered-course that helps them excel in their academic life and learning the English language.

Wax Models

Two early nineteenth century texts treating the production and use of wax models of fruit reveal the history of these objects in the context of courtly decoration. Both sources emphasise the models' decorative qualities and their suitability for display, properties which were not simply by-products of the realism that the use of wax allowed. Thus, such models were not regarded merely as visual aids for educational purposes. The artists who created them sought to entice collectors of art and natural history objects, as well as teachers and scientists. Wax models of fruits are known to have been collected and displayed as early as the seventeenth century, although only one such collection is extant. Before the early nineteenth century models of fruits made from wax or other materials (glass, marble, faience) were considered worthy of display because contemporaries attached great importance to mastery of the cultivation and grafting of fruit trees. This skill could only be demonstrated by actually showing the fruits themselves. Therefore, wax models made before the early nineteenth century may also be regarded as attempts to preserve natural products beyond the point of decay.
