This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.

Hill was born on April 27, 1849 in Waltham, Massachussets, United States. He was the second of six children of Thomas Hill and Ann Foster (Bellows) Hill. His boyhood was passed at Waltham, Yellow Springs, Ohio, and Cambridge, Massachussets.
Hill graduated from Harvard College in 1869. The year after his father's resignation of the presidency he spent a year at the University of Berlin and then, upon the urgent advice of his father, accepted the position of second assistant in chemistry at Harvard.
Hill's career as a teacher centered chiefly in qualitative analysis and organic chemistry. The former he raised from the purely mechanical to a discipline of the highest pedagogical value, admirably adapted to give a student a foundation for a career in research. His lectures in organic chemistry showed his originality of thought and independence of convention. He had an uncanny instinct for separating the essential from the nonessential. Furthermore, he kept always up to date, no easy matter in a rapidly growing science; he frequently reached conclusions on debatable topics ahead of the prevailing opinion of other experts in the field. This was notably true in the case of the constitution of the diazo compounds. Years later the views on this intricate and highly valuable group which he set before his students were adopted by chemists, and they are still held.
In 1874 he published Lecture Notes on Qualitative Analysis. To meet his necessary expenditures, modest as they were, he was obliged to supplement the meager stipend which he received from the College by devoting his spare time to commercial chemistry.
After months of preparatory experimentation, he issued, in 1876, a study of the methyl derivatives of uric acid. His method in this investigation, in the hands of the celebrated German chemist, Emil Fischer, later led to the final explanation of the constitution of uric acid. Induced by Edward Robinson Squibb to undertake the investigation of a previously useless by-product of the manufacture of acetic acid from the distillations of oak wood, Hill found therein abundance of furaldehyde, commonly called furfurol.
Abandoning further work on the constitution of uric acid, he started an intensive investigation of the furaldehyde derivatives which occupied the rest of his scientific career and resulted in thirty publications. His scientific work was conspicuous for his genius in getting at the kernel of a problem, exceptional experimental technique, and painstaking thoroughness. This same thoroughness he demanded from all his students. His criticisms were sharp, but were given only when they were deserved. He became successively assistant professor, 1874, full professor, 1884, and director of the department of chemistry, 1894, holding this last position until his death.
His last illness was short and from the first serious; he died on April 6, 1903, after an operation.
Henry Barker Hill is remembered as the director of the Chemistry Laboratory at Harvard University. He made investigations on food adulterations for the State Board of Health, rendered valuable service in solving chemical problems for a bleachery, and for some years was consulting chemist for the Carter ink company. He was also a prominent science writer, and had published thirty works. Most of his papers were contributed to the Proceedings of the American Academy of Arts and Sciences or to the American Chemical Journal.

Hill was a man of deep religious feeling and set a high standard for things ethical, but he was not a regular church attendant.
Hill was a member of the National Academy of Sciences, and a fellow of the American Academy of Arts and Sciences.
Seemingly austere and impatient, Hill was in reality most kindly, and was helpful to all who came under his influence. Naturally shy and devoted to his work, he became almost a recluse, yet he was a charming companion to the few friends whom he took into his circle.
Hill despised sham and had no patience with any one who showed lack of sincerity.
His health was delicate; the days when he was free from headache and dizziness were exceptional, but he did not permit this weakness to interfere with the performance of his regular duties. Frequently he would hold his lectures under physical discomfort which would have sent the ordinary person to bed.
On September 2, 1871, Hill married Ellen Grace Shepard, the daughter of Otis and Ann (Pope) Shepard of Dorchester, Massachussets, and sister of his father's second wife. His only son became associated with the department of music at Harvard University.
