NOTES. 
When Professor Agassiz gave his opening lecture in the Muse- 
um of Comparative Zoology at Cambridge in 1860, he said that 
American students had been forced to visit Europe, if they were 
desirous of making any extended study in the natural sciences, 
but that he intended to reverse this and compel European students 
to visit America; and by his judicious purchase of type collec- 
tions abroad (thanks to the liberality of citizens and our State) he 
has made his promise good. 
Professor Henry A. Ward of Rochester, New York, formerly a 
student of Professor Agassiz, and since Professor of Geology and 
Zoology in the Rochester University, has, under humbler auspices, 
long been working toward the same end. His large cabinet of 
geology and mineralogy at Rochester is well known to many of 
our readers. He long ago felt the necessity of bringing before 
the American student examples of those larger and rarer fossils 
known to geological science, of which only single specimens ex- 
isted. 
For this purpose he visited Europe, engaged accomplished work- 
men and commenced the foundation of a collection of casts. Wit 
untiring patience and sagacity he secured the moulds of nearly 
everything of importance, at enormous expense, carrying his work- 
men from one museum to the other, and taking moulds of the 
choicest specimens, for a period of three years. 
The difficulties encountered in some of his experiences would 
form an interesting chapter. After many difficulties, he managed 
to secure moulds of the rare Megatherium, Glyptodon, Deinothe- 
rium, Diprotodon, Sivatherium, Colossochelys, Mosasanrus, Plesi- 
collection of casts should be symmetrical and complete, as an 
educational collection, and so was commenced the famous Ward 
collection of casts. Thousands of dollars were spent in buying 
especially choice specimens of the obtainable forms solely for the
