Pathological Examinations. The following table shows the pathological examinations made at the Health Department Laboratory, Museum Street. They are classified according to the nature of the research made, while the solid tissues are subclassified according to results. In all branches of work there is an increase, but most markedly in the urines, which have run from 145 last year to 296; swabs foi diphtheria, from 75 to 169; blood, from 27 to 71 ; and tissues, from 204 to 250. These returns do not include the work I did at the Auckland Laboratory, where many hundreds of specimens in connection with plague were examined by myself or under my supervision. The following table shows general results of the examination of pathological specimens : —
