Excerpt from Laboratory Directions in Histology: A Guide for Use in a Laboratory Course in HistologyThe above, however, presents but the grosser aspect of the necessity of preparation for examination with the microscope. The histological analysis of bodily structure makes further demands on the refinement of methods. Treatment with chemicals and stains (fixation and Staining) has for its purpose not only the preserva tion and delineation of structure, but its identification by means of more or less definite chemical reactions. The goal from this side of histological technique is an analysis from the chemical as well as the morphological aspect and the interpretation of morphology in terms of physiology. Increase in our knowledge of the finer strue ture of the body in the past has been, as advance in the future will be, accompanied by and dependent on the application of a more exact technique along these lines, while for those who aim to do practical work in practical histology and pathology a mastery of the more important methods is indispensable.Furthermore, in working with chemically altered structure there is always the danger of losing sight of the conditions existent in the living protoplasm. It is well, therefore, in addition to study structure in the living or fresh state, as little altered from the natural as may be. There is also very desirable the acquisition of skill in the application of simple methods which require neither ex pensive apparatus nor expenditure of time - methods which while they may not advance knowledge, serve often to meet the needs of a preliminary examination or rapid clinical diagnosis.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
