PRACTICAL CARP CULTURE. 87 



ated not only below but almost under the brain in a cavity excavated in 

 the first vertebra. 



All the various details here given regarding the ear of the fish and 

 especially of the carp are illustrated in the diagrams accompanying this 

 chapter* and the general facts connected with the anatomy of the organ 

 deprived of all unnecessary detail have been explained as fully as the 

 limits allow. It may be as well to state that the article has been drawn 

 up for the use of the general reader and not for the professional anatomist 

 and is consequently as free from technical language as it was desirable to 

 make it. This will 1 hope serve as an apology, if apology is needed, in 

 case these pages should fall into the hands of any student of anatomy and 

 he should be disappointed by the absence of the familiar and time hon- 

 ored, and in the technical treatise useful and indispensable, phraseology. 



In conclusion the writer only desires to express the hope that he has 

 succeeded in presenting the case clearly enough to remove from the mind 

 of his reader any lurking doubt regarding the ability of fish to hear. Such 

 an organ as has been here described can certainly not be without its 

 function and though fish may be comparatively indifferent to sounds in 

 the atmosphere yet they certainly hear vibrations passing through the 

 denser fluid in which they live.
