Born in the vicinity of Lexington, Kentucky, was early distinguished for superior natural energy and mental ability. He was a graduate of Transylvania and most ambitious to take place as member of its Faculty. Appointed to the chair of Institutes of Medicine in 1837, having been called from the Medical College of Ohio, at Cincinnati, where he held a professorship, he occupied the position in Lexington until 1843-44, and died a few years thereafter. He was Dean of the Medical Faculty in 1838. Doctor Cross contributed several papers to the medical journals, but wrote no large work. He was distinguished for readiness and brilliancy rather than for solidity. His strong ambition and self-confidence, with his considerable abilities and extensive reading, gave promise of a most distinguished career, which unhappily a certain want of mental ballast measurably prevented.[79] DOCTOR JOHN EBERLE[80] Was a native of Lancaster County, Pennsylvania, and was a little over fifty years of age at the time of his decease. Born and educated among the Germans of Lancaster, he retained the peculiar accent and idiom of that people to the day of his death, as also their habits of industry and perseverance in favorite pursuits. At an early period of his history, Doctor Eberle was deeply involved in politics and for some time conducted a German political paper. Prior to his removal to Philadelphia, which occurred about the year 1818, he published several interesting papers in the _New York Medical Repository_ and other journals. Shortly after his settlement in Philadelphia, he became the editor of the _American Medical Recorder_, known throughout the country as one of our ablest periodicals. In 1822, his work on _Therapeutics and Materia Medica_ first appeared, after having encountered many obstacles that for a time seemed to preclude its publication. The author assured the writer of this notice that he failed in all his attempts to procure a publisher, who would give him anything for the copyright, until the person who finally became its proprietor offered two hundred and fifty dollars for the work. Being the first book of the author, he accepted the offer in the hope of being more successful in his subsequent undertakings. In 1824, on the establishment of Jefferson Medical College, Doctor Eberle constituted one of its Faculty, and continued in the school until his removal to Cincinnati in 1831. While in Jefferson he taught the Theory and Practice, Materia Medica, and Obstetrics at different periods, and was also engaged as editor of the _American Medical Review_, a journal devoted especially to the interests of that school. While in the Jefferson Faculty he published the first edition of his work on _Practice_, which, it is well known, has passed through several editions, and unlike its predecessor yielded a handsome compensation to its author.
