of health; and in Appendix II., I have added a pricelist of analytical apparatus and reagents referred to in different portions of the work. It will be seen that, as regards food and water, I have only dealt with qualitative examination, so that those who are desirous of becoming proficient in quantitative analysis as well should procure Dr. Parkes' Manual. While I have endeavoured to notice briefly all the points which are of importance to medical officers of health, I have so arranged the work that it may prove useful as a text-book to medical students, and as a handy book to medical practitioners generally. To all those outside the profession who are interested in sanitary matters, and who may care to read the work, I may at least say that it contains some amount of information freed from technicalities and worth knowing.
