Published in 1870, The Cell Doctrine is a seminal work in the field of biology that puts forth the idea that all living organisms are composed of cells. Tyson's clear and concise writing style makes this book accessible to a general reader while providing valuable insights to students and researchers alike. This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

From Cells to Organisms


Book Description

This book uses the history of cell theory to explore the emergence of biology as a distinct field in its own right--separate from anatomy, physiology, and natural history. It also explores nineteenth- and twentieth-century ideas about heredity and development and the progress that was made at the turn of the century when they began to be studied on their own--leading to new understandings of a variety of biological problems, from evolution to cancer. Investigating this story will help readers gain an appreciation of the historical development of scientific ideas. It beautifully illustrates that the process of science is not as straightforward as it is usually portrayed. One of the important lessons of this intriguing story is that "facts" do not necessarily speak for themselves, and observations always need to be interpreted.

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.




The Cell Doctrine


Book Description

THE CELL DOCTRINE - ITS HISTORY AND PRESENT STATE - By Tyson, James - 1870 - THE author has become convinced, by several years intimate intercourse with students of medicine, that their acqaintance with the subjects he has endeavored to include in this little volume would be facilitated, if the views, which are now taught and scattered throughout the often expen- sive works of their authors, were collected in a convenient form for study and reference. Taking it for granted that a knowledge of this subject is of fundamental importance in its bearing upon the study of physiology and pathology, and stimulated by the frequent inquiries of students for an appropriate source of information, he has prepared what he now submits to thenz. He has sought to obtain a continuous history of the evolution of the cell doctrine up to its present state, without embarrassing his pages with a large number of isolated facts. He has attempted, however, to secure a completeness, and to make the work useful to physicians and others engaged in research, by careful references, and the addition of a bibliography, which he has sought to make accurate and extended. Some authors may have been overlooked such the writer cordially invites to send him references to their own papers, or to those of others they believe to have a bearing upon the............




The Birth of the Cell


Book Description

Henry Harris here provides an account of how scientists came to understand that the bodies of all living things are composed of microscopic units thta we now call cells. Harris turns to the primary literature - the original texts, scientific papers, and correspondance of medical researchers involved in the formulation of the cell doctrine - to reconstruct the events that enabled researchers to comprehend the nature and purpose of cells. Translating many of these documents into English for the first time, Harris uncovers a version of events quite different from that described in conventional science textbooks. Focusing on the scientific history of the genesis of the cell doctrine, the author also considers contemporary social and political contexts and shows how these influenced what experiments were undertaken and how the results were represented.




Cell Theory


Book Description

The cell theory is the guiding doctrine about cells and living organisms. It states that all living organisms are made up of one or more cells and that growth and development results from the division and differentiation of cells. This makes the cell the basic structural unit of life. Cell Theory traces the history of the development of the cell theory, which was first proposed almost 200 years ago, from the discovery of the cell through the investigations used to prove its accuracy. Today, scientists almost universally accept the cell theory. Readers will gain valuable knowledge about this scientific concept, helping them understand this life science topic.
