    Notes: This paper presents information collected during a survey of stream-dwelling triclads in two CO ntrasted areas of North Wales. The first study area was located in Caernarvon-shire on the mainland of North Wales and included a mountainous region rising to over 1000 m with abundant cold springs. In contrast, the study area on the nearby island of Anglesey was characterized by relatively warm, slow-flowing streams passing through gently undulating land which did not rise above 153 m. The object of the survey was to collect background data so that suitable streams could be chosen for more intensive studies on factors determining the distribution and abundance of stream-dwelling triclads. Distribution maps for the commonly occurring species were prepared and observations on the relationship between stream source-type and triclad fauna were obtained. The possible role of interspecific competition was of particular interest in this study and the results of this second phase of the work will be presented in a later paper.

    Notes: Abstract A method is described for accurate, rapid and safe differential staining of squamous and columnar cells in the esophagus. In all 10 patients studied during elective esophagoscopy, instillation of Lugol's solution into the distal esophagus stained the squamous epithelium a gray-black. Columnar epithelium and areas of inflammation remained unstained. A sharp circumferential line at the squamocolumnar junction was obtained in patients with a normal esophagus; this line was irregular in patients with esophagitis. The procedure does not interfere with further histologic staining for permanent slides. Lugol's solution reacts with glycogen in squamous cells, as demonstrated by the PAS and PAS-diastase methods. Under these conditions the effect of Lugol's solution on thyroid function studies other than protein-bound iodine is minimal and of short duration. This staining procedure has significant clinical and research potential because it allows the endoscopist to locate, rapidly and accurately, the squamocolumnar junction, its relationship to other anatomic or pathologic entities and the extent as well as the proximal borders of esophagitis.
