It follows from this that there are very often many drawbacks to transporting a religion from one country into another.
“The pig,” says Mr. de Boulainvilliers, “must be very rare in Arabia, where there are hardly any woods,  and almost nothing fit for these animals to eat ; moreover, the saltiness of the water and food makes people very susceptible to skin diseases.”  This local law could not be good for other countries  where the hog is an almost universal food, and in a sense necessary.
I will offer a reflection here. Santorio has observed that there is little transpiration of the hog flesh we eat,  and that this food even largely prevents the transpiration of other foods ; he has found that the reduction came to one-third.  We know, moreover, that the lack of transpiration causes or irritates skin diseases ; consumption of the pig must therefore be forbidden in climates where people are subject to these diseases, as in the climates of Palestine, Arabia, Egypt and Libya.
