Ira Remsen was Professor of Chemistry in the Johns Hopkins University. This Third Edition has been enlarged and thoroughly revised. "........deeper satisfaction is to be found in this evidence of the growing recognition of the importance of Theoretical Chemistry as an element of a thorough education, both in Chemistry and Medicine."

This item is a good example of a pre 1960's school science reference books. It contains sketches of experimental apparatus and not colored photographs of later text books. Although the sketches are very instructional they do not show the various colours obtained when mixing some compounds. The history of reprints demonstrates the quality of the information and the ease of study for students using this book. The era of this publication was a time when sources for knowledge in schools was restricted to mainly school books and teacher demonstrations. The student in the 2 Millennium has a far greater reference source available e.g. the internet. This book is significant to the Kiewa Valley as the Davies family (Tas Davies, penned on the first page), belong to the early settlers of the valley. The book acknowledges that although the region was relatively isolated up to the mid 1900s, the good teaching methods of local schools did not suffer in this rural area. This region was not in the backwaters of scholarly development and modern progressive thought. As with "school of the air" distances in rural areas, between centres of learning and recipients, became irrelevant provided that the social stimulant to learn exists. The "local school" mind set within rural areas was, even before the improvement of the communication "explosion" of the early 1900s followed by the internet facilities of the late 1900s, the greatest drive in cutting the anomalies between city and rural learning facilities. Government decentralising higher education facilities into regional centres (Wodonga - Albury) provided greater access for the learned mind.This item (book) has a faded red colour, hard cover with black print and rectangular design.

Saccharin is an artificial sweetener. The basic substance, benzoic sulfilimine, has effectively no food energy and is much sweeter than sucrose, but has a bitter or metallic aftertaste, especially at high concentrations. It is used to sweeten products such as drinks, candies, , medicines, and toothpaste. Saccharin derives its name from the word "saccharine", meaning of, relating to, or resembling sugar. The form used as an artificial sweetener is usually its sodium salt. Saccharin was produced first in 1878 by Constantin Fahlberg, a chemist working on coal tar derivatives in Ira Remsen's laboratory at the Johns Hopkins University, Baltimore, Maryland USA. Although saccharin was commercialized not long after its discovery, it was not until sugar shortages during World War I that its use became widespread.
