qjo Mr. Home’s Observations on the Camel's Stomach 
simple in its structure that it is not easy to ascertain its parti- 
cular office. It cannot be compared to any of the preparatory 
stomachs of the bullock, as all of them have a cuticular 
lining, which this has not ; we must therefore consider it as 
a cavity peculiar to ruminants without horns ; and a fourth, 
or true digesting stomach. 
It is stated by authors that hares, rabbits, and even some 
men ruminate ; their doing so is not material to the present 
inquiry, since their stomachs are not of that kind which makes 
rumination a necessary part of the process of digestion ; and 
as far as I can learn from some persons who feed rabbits and 
fatten them with meal, although they have watched their 
rabbits with attention they never saw them bring up the food 
into the mouth. It may therefore be only occasional when 
they eat particular kinds of vegetables. They have indeed a 
mode of working their lips when sitting quiet, which may 
have been mistaken for rumination. When it takes place in 
men it must be considered as a disease. 
From the facts which have been stated, the following gra- 
dation of ruminating stomachs is established. 
The ruminants with horns, as the bullock, sheep, &c. 
have two preparatory stomachs for the food previous to ru- 
mination, and one for the food to be received in after rumi- 
nation before it is digested. 
The ruminants without horns, as the camel, dromedary, 
and lama, have one preparatory stomach before rumination, 
and, properly speaking, none in which the cud can be after- 
wards retained before it goes into the digesting stomach. 
Those animals who eat the same kind of food with the
