circumstances; and differing not more widely from each other (if, 

 indeed, as much) than the different forme of remittent and malarial 

 fevers. Yet no one has undertaken to separate these farther than 



as varieties of the same class. "Gaultier de Claubry," he remarks, 

 "has satisfied Louis that typhoid fever is identical with the typhus 

 of camps and jails." Camp and jail fevers have always been ranged 

 by English writers as true typhus — petechial typhus. "If this be 

 true," he continues, "then, as it has been proved by Gaultier dc 

 Chaubrythat camp fever is nothing more than typhoid fever, things 

 equal to the same thing arc equal to each other, and the typhus and 

 typhoid varieties of continued fever arc one and the same disease, 

 and have the same geographical range." "As regards duration, the 

 typhoid variety of continued fever seems to be more protracted than 

 typhus, owing probably to the fact that the complication of intesti- 

 nal inflammation is more common in the former than in the latter. 

 Typhus is primarily a more severe disease, and terminates more 

 rapidly either in death or convalescence." The views so forcibly 

 put forward in the article just quoted from, seem fully sustained by 

 the history of ship fever in Philadelphia, as related byDrs. Condie, 

 Benedict, and Bell in the Transactions of the College of Pln/sirians, 

 and also by that given of the same disease in New York and Boston 

 by numerous writers in the New York and Boston Journals. 



57. The next form of fever to which the Committee would turn 

 their attention is yellow fever. Several interesting and important 

 points in the history of this disease are discussed at much length, 

 and with great ability in the Journals of the pasl year. One of 

 these is the identity or non-identity of yellow and periodic fevers. 

 Dr. J. C. Nott, in the American, Charleston, and New Orleans 

 Journals, maintains the opinion, which has Long been held by Dick- 

 son and others in Charleston, that these forms of disease are essen- 

 tially distinct. Some able articles on the subject in the Medico- 

 Chirurgical Review, duly and October, 1847, take the other side, 

 which is also maintained by Dr. Lewis in his Jledical History of 

 Alabama, published in the May, July, and September numbers of 

 the Xetr ()rl<<(iis Journal for 1S4T. Dr. Nott remarks, that there 

 are sometimes remissions, owing to flagging of the heart under the 

 deadly effect of the poison; but they are not characteristic. In 

 the worst forms of the disease, the fever is sometimes altogether 

 wanting. During an epidemic of yellow fever, intermittent and re- 

 mittent fevers may change their type and terminate in yellow fever.
