People imagine that the progress and prosperity

 petty jealousy and the expression of ill will on the 

 part of those who are second-rate men of science. 

 On the other hand, truly distinguished scientific 

 men are mostly only too glad to assist earnest, hard- 

 working, and meritorious students. Linnaeus found
