The three specimens described above are assigned to the same species. The sulci are shallow but easily distinguishable, and visible on all specimens. The cusp is broad and pointed and, in adult specimens, the anteriormost denticle can be markedly bigger than the rest, especially in the short form. The number of conodont specimens was defined as the number of all identifiable conodont elements in a representative part of the 0.5-0.071 mm fraction. About 50 specimens, mostly proximal ends, preserved in partial relief on two small pieces of shale. Further, it seems as if the frequency of specimens with distinct cusp and denticles decreases somewhat with age. Cardiac malpositions: an overview based on study of sixty-five necropsy specimens. Of the school contacts, 1334 (67 %) agreed to participate, although nine gave specimens unsuitable for serological tests. Environmental/food samples and stool specimens of food handlers were taken from the observed facilities. In all these fields, a good reference collection of real specimens is, of course, indispensable. Fourteen specimens with problematic identification in field were collected for further analysis. Climbers were identified to species or morphospecies using vegetative characteristics of sterile specimens collected or observed in the field. To minimize damage to long-term study sites, substrate was not manipulated in searching for specimens. Herbarium specimens provide vast and important resources for this type of ecological research. Nets were visited approximately every hour and specimens collected in cloth bags. In specimens observed within 5 s of the change in conductance, the acrosomal process projected through the vitelline layer and abutted the egg plasma membrane. The first signs of cells division were observed on 2 h specimens. Through the "trading zone" that had been just opened he "reaped a splendid harvest" of more than 300 specimens in less than six hours. I see no ground for assuming that they are different specimens because parties differ in the result about them. They are made much of as specimens or rarities. All specimens were imaged using similar settings to allow comparison of phospho-antibody labeling in different parts of the retina and under different conditions. Similarly, same size bands were obtained from test thrips specimens collected from onion and watermelon. The sheer volume of the collections of specimens secured was impressive. They made extensive collections of insects, other invertebrates, and geological specimens. At the centre of the chamber base, a typical, rather small basal scar can be observed on all specimens, consisting of two concentric circles. Traps were installed overnight and captured specimens were kept in cages in humid and cold conditions. Caution is certainly warranted when interpreting these records ; not all specimens may be correctly identified. As happened to me many years ago, our students frequently become fascinated by the beauty and variety of form of wellmounted slide specimens of trematodes. In six cases, the gene was analysed in two different specimens and the same sequence was identified. The figures for higher taxa also include specimens not identified to species level and larval stages. No bacterial or parasitic pathogens were identified in the faecal specimens. Thereafter, the trainee should take the opportunity regularly to review specimens under expert guidance. The most complete specimens show straight, apparently rigid stems, with small leaves attached laterally in two rows along the stem. Two specimens show fragments of similar-sized, curved leaves, partly preserved as fusain. Dated herbarium specimens provide useful material for longevity tests. Environmental swab specimens were taken from several locations of the food processing equipment after it had been cleaned using routine cleaning procedures. As these two specimens had undergone separation using sodium polytungstate, it was assumed that part of the signals resulted from incomplete washing. Species discrimination was confirmed independently by isoenzyme analyses and examination of sections of respective specimens. The reliability of a book such as this depends very much on authoritative identification and deposition of voucher specimens. A few specimens show evidence of having been woven, but fragments of this size might not be expected to provide such evidence. Four samples were examined from each tube, and all specimens which failed to show any eggs were re-examined four more times. Most specimens are flattened internal or external moulds, though threedimensional preservation also occurs. Fully-formed specimens were selected and carefully separated from sporocyst remains before being washed in a further ten changes of the filtered seawater. Pre-deployment serum specimens were unavailable for 67 individuals and post-deployment serum specimens were not found for 64 individuals. In 10 (12.4%) other specimens, the aortic valve showed three leaflets and similar circumferential distances between the commissures when viewed from the aortic aspect. Figures were drawn with the aid of a camera lucida, and details added freehand from observations made on live specimens. The specimens described differ mainly in the features of the cephalic region. According to a standardized protocol, specimens of 12 different regions of the lung were taken. Using this method we recruited 55 control passengers who were asked to complete a questionnaire and provide specimens (as above). In order to do this, these developmental sequences have been photographed at regular intervals and followed through to the final moult in single living specimens. The exact source of the introduced specimens has not been determined. As far as possible, we attempted to equalize the number of specimens by species taken during any sampling period. The sample was stratified by age and rural-urban environment, and informed consent obtained to take blood specimens from subjects attending phlebotomy centres. Provenance and age of bacteria-like structures locations from which the specimens were obtained from were as follows. The growths were of mixed organisms and showed morphologically similar bacteria in all specimens that were the same as the bacteria grown from guano. On both slides the specimens have been rather badly crushed under the coverslip. In our present study, all 12 specimens collected were concentrated in parallel with the two methods adjusting the nominal concentration power to 100-fold. The eels of each species were divided into four groups, each containing approximately 25 specimens and acclimated for two weeks prior to the experimentation. Complete valves of ostracodes, or their large identifiable fragments were counted as specimens in a representative part of the 1-0.5 mm fraction. Eight of these specimens were in pre-implantation stages and four of these were grossly abnormal and presumably non-viable. Descriptions of larvae and adult stages are based on measurements of a minimum of 10 specimens fixed in 10% formalin. All measurements and morphological characterization were made on fixed and stained specimens. A few specimens were lost during transfer between different culture media or between culture medium and microscopic slides. Measurements are based on ten specimens unless otherwise stated. Stool specimens were obtained and tested for 23 ill persons who selfreported that they were wedding participants. Blood specimens were obtained from healthy as well as from diseased animals during various veterinary interventions. The specimens were collected by veterinarians from individual animals with watery diarrhoea and\\or herds with high mortality in the young animals. Further, linear discriminant analysis provides a tool for assigning probabilities of correct identification for certain difficult specimens that appear to be intermediate. Separate axon diameter spectra were determined at different locations in cross sections of the two specimens. Despite some variation in the intensity of staining between specimens, these cells could be reliably identified in the peroxidase-labeled whole mounts. In many specimens, dark stripes cannot be differentiated clearly into thick versus thin. The comparison among specimens, from different field populations, presented a limited intrapopulation but high interpopulation heterogeneity. In a standard high-speed centrifuge, only two specimens of this volume range can be processed simultaneously. The proportion of cases with two adequate specimens increased from 57 % to 80 % during this period. Only 3.8% of the rodents were parasitized with three or more specimens of the parasite, and that was only in autumn. In addition, 22 potassium-dichromate-preserved stool specimens from symptomatic patients were examined. Cases with positive cultures for coagulase-negative staphylococci were included if two specimens collected at the same time were positive. After clinical examination, specimens were collected for microbiologic investigations. The majority of the specimens were obtained from the field. In both cases, the specimens from each of these species pairs are intermingled and do not form monophyletic groups by any of the methods used. The peritoneal cavity also contained several specimens which had no doubt escaped from the stomach through the sinuses leading to the peritoneum. Both are usually estimated using data derived by scanning tunneling microscopy from different surface specimens. More detailed contextual analyses of macrobotanical specimens is needed to determine their par ticular role. Two of the unfinished specimens are of quartzite. There seems little doubt that these specimens are the result of bipolar flaking, particularly of quartzite. The three largest specimens are of coarse vesicular lava. Most specimens have a length of 5-7 cm. Complete specimens are usually in the range 3-8 cm. Complete specimens are generally 2-3 cm long. Complete specimens are usually 1⁄2-3 cm long. We also tested protein accumulation levels in the specimens examined by western blot analysis. Five specimens were tested for each type of implant. The ages of the human specimens ranged from 20 to 75 years, with a mean of 62 years. Ligament tearing was predominant in the specimens from younger humans and from rhesus monkeys. In the specimens obtained 1 week after the procedure, the epithelium covering the stroma in the ablated zone demonstrated mild hyperplasia. Frozen sections were cut from primary breast carcinoma specimens and stained with hematoxylin and eosin to confirm tumor content. Real specimens too can be available so that the size of an organ, or the appearance of tissue can be appreciated. Measurements of quantitative characters given in the species descriptions are based on specimens which were available at the time this study was conducted.
