Apprenticed in 1863 to W. J. M. Gordon & Brother, pharmacists, of Cincinnati, a goodly share of my time for a considerable period was devoted to the care of the soda fountain. As part of my duties, when I had advanced sufficiently, it devolved upon me to make the syrups and "charge the fountain"; and those who know Mr. Gordon recognize the fact that strict attention to business was a necessity with an apprentice in his charge. Neither expense nor pains were to be spared in details connected with the manufacture of his syrups, and neither excuse nor apology would prevent a reprimand when the boy was unlucky enough to need one. Necessity demanded, therefore, that as "soda boy" I should attend strictly to business; and, as I recall those days, I earnestly and heartily thank Mr. Gordon for his good judgment in demanding of me what I considered at that time unnecessary exactitude in such little matters as attention to details of the soda fountain. This discipline extended and continued, step by step, until I reached and stood behind the prescription counter; and now in formulating this little monograph, as the formulae recorded herein come successively to my mind, I seem to live over again those early days of "soda-water" apprenticeship.

Since that time I have continuously contributed to others formulae learned in those days and thereafter, both for making flavoring extracts and soda syrups, and have sought the experiences of others, but, so far as I can remember, this is the first appearance in print of any of the formulae. I can say to the reader, therefore, that many of the formulae of this work are such as were used successfully years ago and are now prized in numbers of stores; some of them came into my possession during my apprenticeship, others I have formulated in after-years, and many have been given me by recent acquaintances and friends of the professionfor I have not been actively engaged as a dispenser for some years. Necessarily, however, there is a general similarity in formulae of this description.

I may add that, when it became evident that this work was to be written, only a few days were at my command, and I had no opportunity to consult current literature on the subject. The remarks I make and the formulae embraced herein are dictated to a stenographer, being such as are part of my laboratory processes or come to memory spontaneously; and yet, since a collection of such formulae necessarily covers an experience of considerable time, their several values may be greater than though I should at tempt to collate from the printed work of others.
