538 Dr. Walter Adam on the 



TABLES. 



In the first columns of the following Tables are the actual 

 measurements of an individual Camel, taken with compasses 

 and callipers, of a radius suited to the extent of the bones ; the 

 girths of course otherwise. 



The measurements of the first columns are in the next column 

 adjusted to the normal proportion, on the assumption that the 

 aberrations in the form of an individual animal from the perfect 

 form of its species may be at least as great as the inequalities of 

 the right and the left sides of that individual animal. But the 

 numbers assigned for these normal proportions are meant rather 

 as an indication of what they may be, than as an averment that 

 they really are as stated. Several, especially of those given for 

 the vertebral dimensions, must be erroneous : they have been 

 inserted for facility of comparison. Few adjustments exceed a 

 quarter of an inch, — trifling in so large an animal, — and being 

 placed beside the number of the actual measurement they can 

 lead to no mistake. 



It is not improbable, that the symmetry of the swift Drome- 

 daries will be found to be much more complete than that of the 

 Baggage-camel. 



The proportional parts in the penultimate column are 72nd 

 parts of the basilar length of the cranium. This length being in 

 the animal examined 18 inches, the proportional parts are the 

 numbers in the preceding column multiplied by 4. 



The differences occupy the last column. 



The relative position of the numbers in the Tables is the same 

 as that of the parts measured. 



The Roman numerals over the dimensions of the dorsal and 

 of the succeeding vertebrae, refer to the corresponding dimen- 

 sions in the cervical vertebrae.
