A Marmot Squirrel. 277 



hold the pen, while I dictated with specimens and 

 books before me, and we went on rapidly ; we worked 

 hard, and now we are at the end of our labors. I 

 have, at last, prevailed on them to give the Bats. 

 At the end of the work, I intend to give a synopsis 

 and scientific arrangement of all our American spe- 

 cies, including the seals, whales, and porpoises. 

 This will be included in the letter-press of the Third 

 Volume. 



Here I will venture to consult you in regard to 

 the publication of additional plates of species, not 

 figured in the Large Work. A very few small 

 Arvicola and Shrews, we may not obtain, and they 

 cannot be figured ; but nearly all are within our 

 reach. Some of the subscribers have bound up their 

 plates, and there cannot be a sufficient number to 

 make even the half of another Volume. I propose, 

 as all these figures will be contained in the Small 

 ]\'vrk, that they should be inserted in the letter-press 

 of the Large Work, so that the subscribers, by merely 

 paying for the cost of the small plates, would have 

 the work complete what think you of this ? 



What think you of Victor's obtaining one hun- 

 dred and twenty-nine subscribers in about three 

 days, and I think that he will double the number 

 next week ; so, if the " Large Work" will not pay, 

 the "Small" one, and this is large enough, is sure to 

 do it. 



But I had almost forgotten the main object of 

 writing to you. 



Do you remember a small animal, a Spermophile, 

 that resembles "Says' S. lateralis," that you brought 

 to me. I took it for that animal, although Says' 

 description did not exactly suit it. Since then", I 

 have received Says' species, and on comparing them, 

 T find that yours is a new species which I have 

 named Spermophilus Harrisii. Now, as you have
