Synopsis
The powers of living matter are still more characteristic. It is continually wasting away by a kind of internal combustion, but continually repairs the waste by the processes of growth.
Moreover, this growth is of a characteristic kind, differing absolutely from the so-called growth of lifeless things. Crystals and other lifeless bodies grow, if at all, by accretion, or the addition of new particles to the outside. Living matter grows from within by intus-susception, or taking in new particles, and fitting them into the interstices between those already present, throughout the whole mass. And, lastly, living matter not only thus repairs its own waste, but also gives rise by reproduction to new masses of living matter which become detached from the parent mass and enter forthwith upon an independent existence.
Scope of Biology:
"Biology has already been defined as the science which treats of matter in the living state. Whatever pertains to living matter or to living things pertains to biology. The study of the forms of living things, of their habits, actions, nutrition, surroundings, distribution; of their relations to the lifeless world, and to one another.
About William Thompson Sedgwick
William Thompson Sedgwick (1855–1921) was a teacher, epidemiologist, bacteriologist, and a key figure in shaping public health in the United States. He was president of many scientific and professional organizations during his lifetime including president of the American Public Health Association in 1915. He was one of three founders of the joint MIT-Harvard School of Public Health in 1913.
In 1883, Sedgwick was appointed to the faculty at MIT. He was promoted to associate professor in 1884 and to full professor in 1891. He became head of what ultimately became known as the Department of Biology at MIT. In 1888, Sedgwick began giving lectures in bacteriology to students in the civil engineering curriculum. His students became the spokesmen and practitioners who brought the principles of public health into the practice of engineering beginning in the 1890s and lasting well into the 20th century.
