Albert Allen Wright— Wright. 67 
gical survey of Ohio to make a report upon the lake ridges 
of Lorain county. The published results of his work remain 
the standard source of information concerning that locality. 
In 1884 he was employed to make the report upon the coal- 
seams of Holmes county, and in 1893 he was asked to make, 
for the current volume of the Survey, a report on "The Ven- 
tral Armor of Dinichthys," based upon the unique specimens 
from Lorain county preserved in the Oberlin college 
museum, in which he demonstrated that what are described 
by Dr. Newberry as jugulars are really the "companions of 
his anterior ventrals." 
Among the most commendable aspects of professor 
Wright's scientific work are those which come to light in 
connection with his practical interest in the affairs of the 
town and state. Such confidence did his fellow-citizens 
have in both his attainments and his character that as soon 
as they contemplated the inauguration of a sewer system and 
waterworks he was chosen by universal consent to be the 
leader in formulating plans. After an untold amount of ex- 
amination of the local conditions, and of study of the subject 
from every point of view, he presented plans which were ac- 
cepted, and which, executed under his direction, have secured 
to Oberlin the model equipment of the state, to which the 
State Board- of Health is constantly referring committees 
from other localities. All this was accomplished at a mini- 
mum of expense to the town. It is also through professor 
Wright's influence chiefly that the legislature of the State 
was persuaded to co-operate with the United States geolo- 
gical survey inaugurating a topographical survey of Ohio. 
His papers, presented to the committees of three different 
legislatures, and others published broadcast throughout the 
state, are models both in the statement of the scientific re- 
sults to be published and of the practical ends to be secured, 
in order to justify the large appropriations made.
