In writing this little book, the author has been actuated by a desire to bring home to those interested in dairy work the vital importance of sterilising milk, and to set before them those methods by which this may be most cheaply and effectively accomplished.

The author has also endeavoured to avoid the use of such technical terms as would be likely to be unintelligible to the average reader.

“... The book will be read by the lay reader with advantage, since it points out the dangers arising from infected milk and the advantages of sterilised milk.”—Lancet.

“... The author has produced a handbook that will be found intelligible even to those having only an elementary knowledge of dairying....”—Dairy World.
