23. Malaria. — Marchetti* has advanced an opinion on the origin 

 of malaria, which is only noticed by the committee because it is so 

 different from what the experience of our southern country affords on 

 the same subject. He considers salt marsh exhalations as more insa- 

 lubrious than those from fresh water. The sea marshes may be 

 made healthy, he thinks, by keeping out the salt water. He supposes, 

 in order to explain this, that marine vegetables putrefy quicker than 

 those of fresh water. 



Rigaud de l'lslef detected an unctuous animal matter, of a cada- 

 veric odour, in marsh air, thus confirming the experiments of The- 

 nard and Moschctti. 



Levy, in his Traiie a" Hygiene, % supports the organic nature 

 of miasmata, attributing its noxious influence to that, and not to 

 carburetted hydrogen. 



Dr. J. C. Nott has ably advocated the same views in several of the 

 Journals of this country, with especial regard to the originating 

 cause of yellow fever. In Dr. Lewis' Medical History of Alabama,§ 

 there is much very valuable matter on this subject; but the com- 

 mittee cannot further notice, here, the valuable contributions which 

 this gentleman has made to the history of southern medicine. 



GENERAL PATHOLOGY AND THERAPEUTICS. 



24. These subjects come next in order, and, in discussing them, 

 the committee will be under the necessity of exercising a privilege 

 of selection, as the materials arc too abundant for all to be noticed. 



The blood itself, the great vehicle of morbific matter, deserves the 

 committee's first attention. 



Some of the observations they have selected date a little previous 

 to the year just passed, but they are sufficiently important in them- 

 selves to entitle them to notice; and are, besides, only noAV coming 

 before the public in a more accessible form. Simon|| gives the fol- 

 lowing division of the diseased conditions of the blood: 1st, Ilypcri- 

 nosis; 2d, Hypinosis; 3d, Spancemia; 4th, Iletcrochymeusis.
