Preliminary Report of the Committee on Anatomical 



Nomenclature, adopted Dec. 28, 1889 by the Association 



of American Anatomists without dissent. 



„The Committee recommend: 



1. That the adjectives dorsal and ventral be employed in 

 place of posterior and anterior as commonly used in human anatomy, 

 and in place of upper and lower as sometimes used in comparative 

 anatomy. 



2. That the cornua of the spinal cord, and the spinal nerve-roots, 

 be designated as dorsal and ventral — rather than as posterior and 

 anterior. 



3. That the costiferous vertebrae be called thoracic rather 

 than dorsal. 



4. That the hippocampus minor be called calcar, the hippo- 

 campus major, hippocampus; the pons Varolii, pons; the insula 

 Reilii, insula; pia mater and dura mater, respectively pia and 

 dura." 



Signed by all the members.
