more violent and dangerous form. The latter fact holds good of
yellow, as well as of remittent fever.
Dr. Boudin, in his 11 Lettres sur l’Algérie,” after establishing the
persistent influence of marsh malaria on French and English colonists,
continues thus :
“ Reste à examiner l’influence exercée sur le chiffre des décès par le séjour dans les
localités de l’Algérie, non sujettes aux émanations paludéennes, mais se distinguant de la
France uniquement par une température élevée. A défaut de documents assez nombreux
recueillis en Algérie même, nous invoquerons les faits relatifs à deux possessions anglaises
ayant la plus grande analogie thermométrique avec notre possession africaine ; nous voulons
parler: 1°, du Cap de Bonne-Espérance; 2°, de Malte: l’un et l’autre proverbialement
exemptés de l’élément paludéen.
“ Au Cap de Bonne-Espérance, la mortalité de trois régiments anglais, de 1881 à 1836,
a été représentée par les nombres suivants :
En 1831 ....................... .......................................... .................... ............... ,26 décès.
“ 1832 ................................................................................ .......... 26
“ 1833 . ...v. J . . . . . . . v . . . ............... 28
“ 1 8 3 4 ....... ............ ..................... ........ ........................... 28
“ 1 8 3 5 ......................................................... ................................. 34
| 1836 ....................¿V. .........
“ A Malte, où l’on peut considérer les hommes les plus jeunes comme les plus récemment
arrivés d’Angleterre, la proportion des décès a suivi la marche ci-après.
Au-dessous de 18 ans ...... . 10 décès sur 1000 hommes.
De 18 à 2 5 ............. ................. 18.7 , “ .
“ 25 à 33...°........23.6 “
- “ 33 à 4 0 .......... ................................................ 29.5 “
“ 40 à 50................... I.. .................... .................... 34.4 “
“ En résumé, les analogies puisées, non seulement dans les localités paludéennes, mais
encore dans les contrées non marécageuses, ayant une plus grande analogie clhnatologique
avec l’Algérie, se montrent peu favorable à l’hypothèse de l’acclimatment.”
He then goes on to give statistics hoth of the civil and military
population of Algeria, which show still more deadly effects of
climate.
If we turn now to the physical history of the Hegro, we shall find
the picture completely reversed. He is the native of the hottest
region on the globe, where he goes' naked in the scorching rays of
the sun, and can lie down and sleep on the ground in a temperature
of at least 150° of Fahrenheit, where the white man would die in a
few hours. And while the degenerate tropical descendants of the
whites are regenerated by transportation to cold parallels of the
temperate zone, experience abundantly proves that, in America, the
Negro steadily deteriorates, and becomes exterminated north of about
40° north latitude. The statistics of Hew England, Hew York, and
Philadelphia, abundantly prove this. The mortality of blacks in
our Horthern States averages about double that of the whites ; and
although their natural improvidence and social condition may, and
do, have an influence on this result, still, no one conversant with
the facts will deny the baneful influence of cold upon the race.

We may here refer to another curious train of facts, in connection
wi the adaptability of the above races to climate. We allude to
the results of crossing or breeding them together, which seem best
explained by the laws of hybridity. The mulattoes, no matter
where born, north or south, possess characteristics, in reference to
medical climate, intermediate between the pure races. The mulatto
j brought from Maryland or Virginia to Mobile or Hew Orleans
suffer infinitely less from the diseases of these localities, than do the
pure whites of the same States. In fact, the smallest admixture of
gro blood, as m the Quarteroon or Quinteroon, is a great, though
not absolute, protection against yellow fever. We have in the
