Excerpt from Studies in the Theory of Descent, Vol. 1 of 2 Since every new contribution to science is a fresh starting-point for future work, I may venture without any great breach of propriety to dwell briefly upon one or two of the main points which appear to me to be suggested by Prof. Weis mann's investigations.

Book Description
Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Book Description
Excerpt from Studies in the Theory of Descent, Vol. 1 of 2 The present work by Professor Weismann, well known for his profound embryological investigations on the Diptera, will appear, I believe, to every naturalist extremely interesting and well deserving of careful study. Any one looking at the longitudinal and oblique stripes, often of various and bright colours, on the caterpillars of Sphipx-moths, would naturally be inclined to doubt whether these could be of the least use to the insect; in the olden time they would have been called freaks of Nature. But the present book shows that in most cases the colouring can hardly fail to be of high importance as a protection. This indeed was proved experimentally in one of the most curious instances described, in which the thickened anterior end of the caterpillar bear$ two large ocelli or eye-like spots, which give to the creature so formidable an appearance that birds were frightened away. But the mere explanation of the colouring of these caterpillars is but a very small part of the merit of the work.

Book Description
Excerpt from Studies in the Theory of Descent, Vol. 2 of 2 If variability is to be understood as indicating the period of re-modelling of a living form, whether in its totality or only in single characters or groups of characters, from the simple fact of the hetero chronic variability of the ontogenetic stages, it fol lows that the latter can be modified individually, and that the re-modelling of one stage by no means necessarily entails that of the others. It cannot however be doubted that variability, from whatever cause it may have arisen, is in all cases competent to produce a new form. From the continued crossing of variable individuals alone, an equalization of differences must at length take place, and with this a new, although not always a widely deviating, constant form must arise.

Book Description
Studies In The Theory Of Descent (Volume II): With Notes And Additions By The Author Translated And Edited, With Notes, By Raphael Meldola With A Prefatory Notice By Charles Darwin (Complete Edition Of Two Volumes - Vol. II.) This book is a result of an effort made by us towards making a contribution to the preservation and repair of original classic literature. In an attempt to preserve, improve and recreate the original content, we have worked towards: 1. Type-setting & Reformatting: The complete work has been re-designed via professional layout, formatting and type-setting tools to re-create the same edition with rich typography, graphics, high quality images, and table elements, giving our readers the feel of holding a 'fresh and newly' reprinted and/or revised edition, as opposed to other scanned & printed (Optical Character Recognition - OCR) reproductions. 2. Correction of imperfections: As the work was re-created from the scratch, therefore, it was vetted to rectify certain conventional norms with regard to typographical mistakes, hyphenations, punctuations, blurred images, missing content/pages, and/or other related subject matters, upon our consideration. Every attempt was made to rectify the imperfections related to omitted constructs in the original edition via other references. However, a few of such imperfections which could not be rectified due to intentional\unintentional omission of content in the original edition, were inherited and preserved from the original work to maintain the authenticity and construct, relevant to the work. We believe that this work holds historical, cultural and/or intellectual importance in the literary works community, therefore despite the oddities, we accounted the work for print as a part of our continuing effort towards preservation of literary work and our contribution towards the development of the society as a whole, driven by our beliefs. We are grateful to our readers for putting their faith in us and accepting our imperfections with regard to preservation of the historical content. HAPPY READING!
