    PLATE 2.—Epithelial tissues. Fio. 1.—Portion of the Great Omentum of a Rabbit, the Cell Outlines Bein}>: Blackened by Silver, X 280. The lifjure shows two layers of a sini])le ])avemeiit epithelium (per- itoneal me.sothelium). The cell boundaries are black, niiclei are stained blue. Tecbnic : Silver iin])regnation. 1 leinato.xylin. Reference letters: Nuclei of su])erlieial epitbelial layer; A-j, nuclei of deeper c])ithelial layer. Flu. 2.—Stratified Squamous Epithelium from the Human Mouth. X 280. The jireparation was taken from one who had been executed. 'I’lie iigure shows the typical sti'uetnre of stratilied s<]uamous ein- tbelinm, with indentations of the ba.sjil layer caused by low jiapillm of the mucosii. The deepest layer is cylindric, the most superlicial layei's are of flattened cells. All the transitional forms arc found between them. In the dcejier layera mito.ses are .seen ; leukocytes are found .sc*attered throup;h the entire thickne.ss of the epithelium. T’echnic: Miiller’s fluid. 1 lematoxylin-eosin. Reference lettci's : I, Jjcukocytes ; w, mitoses; p, papillai. Fiu. 11.—Cylindric Epitheiium from the Human Intestinal Tract. X 420. T'he ])re])aration was taken from one who bad been executed. The liKure shows at the left three isolated cells from the intestinal e))ithelium and at the rif^ht a number of the .same kind of cells, which are still atbichcd. All the cells ja-e.sent on their superficial .surface a striated cnticniar border. Leukocytes are found among the cells, and some of them are acidophile. 'Technic: Potassium bichromate and formalin. Hematoxylin-eosin. Reference letters; /, Leukocytes; eosinophile leukocytes. 1. fluffened or squamous epithelium, consisting of a single layer of epithelial cells which arc generally irregu- larly polygonal. Occurs as the epithelium of the serous cavities (me.sothelinm), of the alveoli of the Inng.s, of cer- tain regions of the inner ear, and the intercalary portions of many gland-ducts. 2. Simple, cidnc epifhelium. Occurs as the e])itheliinn covering the choroid j)lcxns of the brain, tlmt of the lens capsule, of the middle ear (frequently with cilia), of numer- ous glands and excretory ducts of glands. S. Simple roluvmar epifheliinn. Occurs as the o]nthe- lium of the entire intestinal canal, of the gall-bladder, of many gland-ducts.
