We have, therefore, in the following pages endeavoured to present ill a connected form an account of the more important investigations which have been carried out in this department of Bacteriology, i11 the hope that it may prove of service both to the student and investigator, as well as to those who, like engineers and medical officers of health, are practically concerned with the llygieilic aspects of water-supply.
With this object in view, we have given-firstly, a. survey of all the more iinport, ant general methods of bacteriological study, describing in detail those which are specially applicable to the examination of water secondly, we have given an accoui t of tlie principal results hitherto arrived at by the use of the- e new bacteriological inethods in the study of the different kinds of water, and the changes which they undergo through natural ancl artificial agencies further, particular attention has been besto ved on the behaviour of pathogenic bacteria in water, whilst a separate chapter has been devoted to the comparatively novel .
subject of the bactericidal action of light. Finally, we have appended a concise description of the principalcharacters of all the micro-organisms, numbering upwards of 200, which, as far as we have been able to ascertain, have hitherto been found in water and it is hoped that this descriptive catalogue of water bacteria may prove of some value in the at present bewildering task of ident. ifying the different microbial forms met with in natural waters.
