Abstract
IN this work the author sets forth in great detail the results of investigations, extending over six years, upon the minute structure of various bodies, products, for the most part, of the activity of living organisms. The object of these researches was to extend, and to put to the test, certain conclusions reached by the author in 1892, in his well-known work on the structure and physical constitution of protoplasm. In an appendix to the work in question he gave an account of some observations upon the minute structure of certain substances, such as gelatine and egg albumen, which exhibit the phenomena of swelling or of coagulation, and came to the conclusion that these substances possessed a minute structure which was finely honeycombed or alveolar (“Wabig”). In the present work these observations are renewed and greatly extended, both as regards minuteness of detail and in the variety of material. Besides researches upon gelatinous and coagulable substances such as gelatine, celloidin, albumen, and so forth, the author has studied the minute structure of various sphasrocrystals, of natural and artificial cellulose structures, of starch granules, and finally of a number of natural products of animal tissues such as chitin envelopes, spongin fibres, matrix of hyaline cartilage, and other similar structures.
