some of which, as the bees, have a separate receptacle for 

 honey, of which they disgorge a part and then pass on the 

 rest into the real stomach. Then came the snails, in which 

 the stomach is a separate part with a second opening to 

 pass out the food it cannot take up. Then the fishes, some of 

 whom have stomachs strong enough to crush the shells and 

 indigestible parts of their food, while others have the mouth 

 lined with teeth for this purpose ; then came the stomachs 

 of reptiles ; and afterwards those of birds, with the curious 

 crop where the food lies first, and the gizzard, in which it is 

 rubbed against the little stones which the bird swallows. 

 Then finally came the stomachs of the higher animals, with 

 many curious and interesting peculiarities ; as, for example, 

 the divided stomach of those animals, such as the cow, which 

 chew the cud, and of the camel, in which one division serves 

 as a water-bag. And side by side with these organs of 

 digestion he placed the teeth of each animal, showing how 

 these were each exactly fitted to prepare the food for the 

 particular kind of stomach of the animal to which they 

 belonged. 



In this way Hunter tried to arrange the history of all the 

 different organs of the body, tracing out each as perfectly as 

 he could, and showing how it suited the wants of the various 

 animals. His museum cost him an immense amount of labour, 

 and more than ,70,000 in money ; when he died, in 1793, , 

 it was bought by the English Government for ^15,000 and 

 placed in the London College of Surgeons, and since then 

 many a London student of physiology has had occasion to 

 be thankful to the rough and uneducated John Hnnter for 

 the laborious and careful work he did, and the magnificent 

 collection he left behind him.
