of all the species which may exist within your range. You need not 
any reiterated directions to keep the specimens from different locali- 
ties distinct: this is the only classification necessary, however. The 
greater the number of localities, the greater, of course, the interest, 
and complete collections to include all the species for each locality 
will be exceedingly important. Look sharp for the little darters 
among the stones in shallow ripples. . . . Cannot you make

My pear RapicicoLta:— 
I have had your acceptable letter of Sept. 29 in hand several

back about ten days, and have almost hourly intended to write you 
on account of adventure since our delightful partnership in Wisconsin. 
If I mistake not, you already know of our movements up to my 
departure east: how we went to the meeting of the scientific “asses” 
in Cleveland: how I went to Elyria alone, or rather with Prof. 
Andrews and caught prodigious stores of Etheostomas: and returning 
nabbed Dr. Kirtland and posted to Poland, where in one day we 
caught 41 species. How next we went to Detroit and in company 
with our friend Rev. Chas. Fox made extensive rambles through 
Michigan, visited Ann Arbor, Lake Huron, and divers other spots, 
all the time longing for company of yourself and Doctor Barry. (he 
will have the degree one of these days, and I will give it now). 
Well then, after leaving Cleveland I went east, stopping a day 
or two at Syracuse to see what fish inhabited the salt marshes below 
the salt works. I found nothing interesting but mosquitoes, which
