68 SPECIALIZATION IN NATURAL SCIENCE. 



ments, and collections ; all of these are quite costly. Do 

 you need a fairly complete work on the geological fauna 

 of the world ? You can get one in Germany for between 

 $800 and $900. If you wish a work on shells, compre- 

 hensive, and with full and correctly colored plates, you 

 find it in Reeve's Iconica Concliologica ; but it costs in 

 England about $1,000. A work giving a descriptive list 

 of diatoms in our waters, will cost, perhaps, $40. One 

 describing the rhizopods, not far from $35. Edwards' 

 standard work on butterflies, in two series, will cost $30 

 a series. A good library for a working entomologist will 

 cost several hundred dollars. But we are absolutely 

 manacled in scientific work, unless we have such books, 

 if not in our private libraries, at least in those public 

 ones which we can daily consult. It will not answer that 

 they are in a New York or a Philadeljihia library. To 

 be of much use, they must be here. Then there are 

 needed instruments, such as telescopes, spectroscopes, 

 microscopes, general and lithological, aquaria, and vari- 

 ous physical, chemical and dissecting instruments. 



Now. the men who possess the spirit of scientific re- 

 search are rarely the ones who have also the money to 

 buy freely these important tools. Science cannot flour- 

 ish unless the means are freely contributed by men of 

 wealth. 



May we be cheered in our scientific work by the abun- 

 dant contributions of those who are able and willing to 

 help science in this special way. And do not wait, men 

 of wealth, to help the cause in your wills. Imitate that 

 n< >ble benefactor of Yale's scientific schools, Joseph E. 

 Sheffield, who for nearly twenty years had the pleasure 

 of looking daily from the portico of his mansion upon 

 the great schools he had founded, partly on his own 

 lawns. 



This costly building and these liberal endowments are 



present testimonials that our generous founder, Mr. John
