far published. A country situated as Brazil is, far removed from the 
centres of scientific activity, is often the prey of the grossest forms of 
scientific charlatanism. Hartt and his assistants naturally came in 
contact with this class of men, but he so impressed the leading men of 
the empire with his ability and integrity that charlatanism was never 
able, in his presenee, to make much headway. 
That Cornell University has had so long a number of Brazilians 
among her students is to be attributed either directly or indirectly to 
Hartt’s influence ; and whatever helpful, broadening, enlightening 
aspirations these j^ung men may take with them from Cornell, they 
should bear in themselves some remembrance — some saudade — of Prof. 
Hartt w^ho laid down his life for science in Brazil.” 
In conclusion I slionld express my thanks to those who 
have aided, in obtaining the information upon which the pre- 
ceding sketch of the life of Prof. Hartt has been based ; and 
my thanks are especially due to his brother, Mr. George 
Hartt, of Xew York, who kindly loaned the wood-cut which 
faces the title-page. The cut was made by Mr. Hartt himself, 
and is considered a faithful likeness. The autograph is from 
a letter to Mr. J. B. Hegan, written when Hartt was a student 
at Cambridge, and when he gave more expression to his signa- 
ture than he did in later years.
