94 THE INFLUENCE OP CLIMATE. 



The epidemic of 1853, at New Orleans, allowed Barton to 

 make a scale of mortality on the same principle, and absolutely 

 comparable, and which would take away all doubt in this re- 

 spect, if any existed.* 



* Barton, Report of the Sanitary Commission of New Orleans for 1853, p. 

 248, New Orleans, 1854 (see Hirsch, Handbuch, etc., 35). He brings for- 

 ward several pieces of evidence in the same question. They seem to us too 

 decisive, in a polygenist point of view, for us not to give the entire list of 

 his quotations : Romay, Diss. sobre la Fiebre Amarilla, etc., Habana, 1797 : 

 Arnold, Treatise on the Bilious Remittent Fever, etc., p. 26, London, 1840 : 

 Zimpel, Jenaische Annalenfiir Med., i, p. 68: Dickinson, Observations on the 

 Inflammatory Endemic incident to Strangers in the West Indies, etc., p. 13, 

 London, 1819 : Ferguson, Notes and Reflections, p. 150, London, 1846 Dick- 

 son, Philadelphia Med. and Phys. Journal, iii, p. 250 : Lallemand, Das Gelbfleber, 

 etc., p. 121. [Schomburgk, A Description of British Gruiana, etc., p. 22, Lon- 

 don, 1840. EDITOR.]
