(horseshoe crab,) which come over here in such numbers that lately I have with 

 them stocked all the marine aquaria of England and the continent of Europe, 

 and I do not know what to do with those I now have over. I do not like to 

 see the poor things dying by inches, and my mind revolts at plunging animals 

 full of life and health into spirits. It would be well if Linmlas were less hardy.

Athens, August 12, 1867, 



"We have learned, through M. Rangabe, our envoy extraordinary and minister 

 plenipotentiary near the government of the Union, that the directorship of the 

 Institution of Smithson is desirous of entering into relations of exchange with 

 our museum of natural history, with a view to obtaining the natural productions 

 of Greece. We lose no time in expressing the pleasure which this information 

 has given us, and the gratification we shall experience in forming and maintain- 

 ing such relations, which cannot fail to be of great advantage to our own nmseum, 

 inasmuch as our collections are at present but scantily provided with objects 

 pertaining to the natural history of North America. As regards duplicates of 

 the objects of our own country, we have in readiness for oflfering to the Institu- 

 tion : a series of fossil bones of different mammifers (Hippotherium grande ; 

 Rhinoceros partygnathus ; Sus erymauthius; several species of antelope, &c., 

 &o.,) of the pleocene formation of Pikermi, in Attica; a collection of impres- 

 sions of fossil plants of the eocene formation of Koumi, in Enbir; preparations 

 of several kinds of birds of Greece ; eggs of different Greek birds ; marine 

 shells, fresh-water and ten-estrial. 



"We beg to be instructed as to what the Institution would desire, or rather 

 what it would prefer to receive in the first instance, in ordcK that we may bo 

 able at once to make a first remittance. We should be glad, at the same time,' 

 to know by what channel, by what means, and to what address our remittances 

 must be forwarded. It would be esteemed a favor if the authorities of the Insti- 

 tution would inform us in a compendious note what objects it possesses in dupli- 

 cate and at its disposal for exchange, so that we might indicate in turn our own 

 desiderata. 



We have the honor of subscribing ourselves, with assurances of the most dis- 

 tinguished consideration, *

Pakis, September 4, 1867. 



I have received, through M. Bossange, the .case containing 174 volumes of 

 educational books, which you had the goodness to send me. These books foiTQ 

 the admiration of all who take an interest in education, and I hope that Erance 

 will profit by this example. We have excellent things at home by which you 

 in turn might profit ; but we have seen nothing comparable to your " Reader," 

 your "Object Lessons," your '^ Graphics," and your "Geographical Series." 



I send you a letter for each of the editors who has been kind enough to make
