300 INDEX. 



ii. 172. The Guinea-pig has not that natural instinct so 

 common to almost every other creature, iii. 169. 



Intestines, in all animals the size of the intestines proportioned 

 to the nature of the food, ii. 157. Intestines of ruminating 

 animals enlarged by nature, to take in a greater supply ; 

 those of the carnivorous kind are short, also thin and lean, 

 but of the ruminating are strong, fleshy, and covered with 

 fat, 223. Of sheep found to be thirty times the length of 

 the body ; those of the wild cat not above three times the 

 length of its body, 396. Of the rein-deer, washed like our 

 tripe, in high esteem among the Laplanders, 361. Of the 

 bat, in some measure resemble those of man, iii. 233. Those 

 of the manati longer, in proportion, than those of any other 

 creature, the horse excepted, 276. The tribe of woodpeck- 

 ers want that intestine called the caecum, iv. 197. The 

 lamprey seems to have but one, v. 93. Those of the crab 

 have many convolutions, 167. 



Inundations generally greater towards the source of rivers than 

 farther down, and why, i. 178. Some distribute health 

 and plenty ; others cause diseases, famine, and death, 189. 

 Every inundation of the sea attended with some correspon- 

 dent dereliction of another shore ; one of the most consi- 

 derable in history, is that which happened in the reign of 

 Henry I. ; an inundation in the territory of Dort destroyed 

 a hundred thousand persons ; and yet a greater number 

 round the Dullart ; remarkable inundations in Friezland 

 and Zealand, in which more than three hundred villages 

 were overwhelmed ; their remains continue visible at the 

 bottom of the water in a clear day ; some in which the sea 

 has overflowed the country, and afterwards retired, 238. 

 Inundation of the Thames at Dagenham, in Essex, 24-3. 

 Instantly produced by land spouts, 335. 



John-dory, Quin noted for a sauce for this fish, v. 25. 



Ireland not infested with wolves, iii. 42. Frogs designedly 

 introduced into that kingdom some years before the Nor- 

 way rat ; that rat put a stop to their increase, and the frog 

 is once more almost extinct in that kingdom, 176. The 

 mole utterly a stranger there, 197. 



Iron extracted from all the substances upon earth, i. 67. 



Isatis, an animal very common in all northern countries bor- 

 dering upon the Icy Sea, and seldom found in warm cli- 

 mates ; description ; burrows like the fox, and when with 

 young, the female retires to her kennel, in the same man- 

 ner as the fox ; its kennel very narrow, and extremely deep, 

 has many outlets ; manner of coupling, time of gestation, 

 and number of young, all similar to what is found in the 

 fox ; brings forth at the end of May, or the beginning 

 of June ; considered as between the dog and the fox ;
