Abstract
An analysis of this type may be considered from two viewpoints, one of which is essentially that of natural history, the other that which involves its significance for man’s welfare. The first deals with the distribution and physiology of bacteria that arc indigenous to snow. The second concerns the study of the occurrence and physiology of bacteria commonly found in snow but not indigenous to the medium. These are organisms which have come from extraneous sources such as soil, and decomposing plant and animal structures; they include bacteria that may be pathogenic to man if ingested, or that may be associated with pathogenic organisms. "In recent years rapid progress has been made in the study of the ecology of the bacterial flora of fresh water lakes which has resulted in the development of a phase of water bacteriology with aims and techniques different in many respects from those of the more specialised sanitary bacteriology of water.n (1) With this thought in mind the following report will be carried on and a transfer of Information from it to the undertaken analysis will be utilized.
Bacteria are the most numerous and the most widely distributed of living things. They are present not merely at the surface of the earth or in the bodies of water which partially cover it, as are most other living things, but in the soil Itself, and in the air above, and in the waters under the earth.An analysis of this type may be considered from two viewpoints, one of which is essentially that of natural history, the other that which involves its significance for man’s welfare.
