Dear Reader, There are no diseases more common in this nation, and none more difficult to cure, than agues and fevers. They are so challenging that they have become known proverbially as “The Scandal of Physicians.” Even Fernelius, who was considered to have written the best treatise against them, was himself killed by a fever. Nor has there yet been published any remedy as effective as these fiery afflictions are deadly. Accept then this healing balm, gathered from the finest medical knowledge of the Greeks, Romans, and Arabs, by the hands of that incomparable Dr. Bricius Bauderon. His age and experience inspire more confidence in me than the unfathomed mysteries of modern fever treatments. He was eighty years old when he wrote this treatise, and had fifty years of confirmed practice behind what you may now master in a month’s time. His painstaking, long-labored work needs nothing but your acceptance to flourish. For many years, this work has been confined to French and Latin editions, though desired by ambitious scholars as a valuable acquisition. Few private libraries could boast of possessing it, which encouraged me to publish it in this English version. While it may be complete though not as elegant, it is more useful though not as beautiful. Those refined critics who may scoff at it are like the people my author describes, who faint at the smell of a rose—pretentious minds that breathe best in the worst air, or like certain unclean creatures that thrive best in stagnant pools. But I leave them aside and commend this work to the thoughtful reader. It is methodical, accessible, and clear enough to benefit the most ordinary understanding, yet comprehensive enough to satisfy the most learned. Read and be convinced. Yours truly, Thine, B.W.
