The Stomach of Migrating Salmon. — An interesting study of 
the histological changes which the digestive tracts of salmon undergo 
during the migrations of these fishes from salt to fresh water, and 
the reverse, has been made by G. L. Gullard.? At about the time 
the salmon begin to ascend the rivers, or even before, their digestive 
tracts are affected by a desquamative catarrh by which most of the 
digestive epithelium is shed. After the fish have reached the high 
waters and laid their eggs, the stomach reassumes its normal epithe- 
lium, and on their return to the sea the epithelium of the intestine is 
regenerated. The desquamation is evidently not directly or indirectly 
dependent on the action of fresh water, for it may occur in fish that 
are still in salt water. It is more probably associated with changes 
in the feeding habits of the fish correlated with the breeding season.

Terminology of the Central Nervous System. — The Associa- 
tion of American Anatomists has issued in the form of a pamphlet 
the majority and minority reports of its committee on anatomical 
nomenclature. The reports deal with the terminology of the central 
nervous system. The majority report, after a historical summary, 
discusses briefly four categories of terms : first, twenty-three terms 
common to the list of the committee’s secretary and that of the Ana- 
tomische Gesellschaft; secondly, seventy-eight terms common to both 
lists, but with slightly different usages; thirdly, fifteen terms largely 
different in the two lists, but receiving considerable American sup- 
port; and, finally, two hundred and fifty-nine terms differing more or 
less from those adopted by any other organization. The majority 
report is obviously a radical measure, and it is against this side of it 
that the minority report is directed. While the reports contain some 
happy suggestions as to changes in particular terms, and much that 
is valuable on the principles of a logical and convenient nomencla- 
ture, they differ from each other so radically that anything approaching 
the adoption of a uniform system on the part of the committee would 
seem well-nigh impossible. GHP
