Animal and Vegetable Physiology:Considered with Reference to Natural Theology(Volume 2)

In this second volume of his 1834 treatise on how God's creative process is manifest in the plant and animal kingdoms, Peter Roget, compiler of the celebrated Thesaurus, examines their physiologies. He covers aspects including nutrition and respiration, the sensory and nervous systems, the function of the brain and the reproductive process. Functions of individual plants and animals are seen as proving God's design by giving organisms the means of coexisting. The organic development process and change from the first cell beginnings to decay and death is studied closely with the aim of understanding how 'material particles first became animated with the breath of life' and why there is a time limit to their existence. The treatise concludes that God's intention pervades both kingdoms and is revealed in similarity of processes and the universal connectivity of the 'laws of analogy' that link all living things to common roots.
