in their relation to the Seasons. 245 



son variable and cold, preceded besides by the intense cold of 

 winter, the catarrhal affection is united with the inflammatory 

 affections ; while in autumn, a season variable and warm, pre- 

 ceded on the contrary by summer, the catarrhal affection is 

 conjoined with the bilious affection. This last combination is 

 besides very susceptible of degenerating into severe states, 

 and of putting on pernicious forms. The abdominal organs, 

 the intestines am'ong others, more especially suffer. 



Finally, during winter, when the cold prevails, the phlo- 

 gistic affections are most common ; and as, with us, the cold 

 is almost constantly attended with fogs, rains, snow, and 

 great atmospherical a icissitudes, Ihe inflammatoiy affections 

 accompany the catarrhal and mucous : two morbid states ana- 

 logous, but which are not, however, identical. The sangui- '' 

 neous system, and still more the mucous, of all the organism, 

 are then most exposed. 



After having determined the annual diseases of France, 

 taken in mass, M. Fuster compares, in pai'ticular,the differences 

 which characterise the annual diseases of the north and south. 

 In the north as in the south, where the four seasons are very 

 distinct, you also find the corresponding diseases well pro- 

 nounced. The four seasons in the extreme regions are, how- 

 ever, far from always offering an equal preponderance. In 

 the north, the winter is the rudest and longest season ; in the 

 south, on the contrary, the season of summer is invested with 

 these characters. The spring and autumn yield to the influ- 

 cn.'e of the two ]Jowerful seasons which separate them : thus, 

 ^vhile in the north the winter encroaches at once both on the 

 spring and autumn, and extends far into their domain the 

 empire of its qualitiesj in the south the spring and autumn are 

 invaded by the warm season, and more or less strongly im- 

 l)ressed with the burning seal of summer. Hence it results, 

 that in the climates of the north, the meteorological year, more 

 or less analogous to the polar year, takes much more from the 

 winter than from the summer ; while in the climates of the 

 south, the meteorological year, participating more or less of 

 the e(juatorial, is more allied to the summer. 



Thus of diseases and their differences. In the north, the 

 inHammatory affections, the necessary attendants of winter,
