The typical and only specimen is preserved in alcohol. The color above, 

 everywhere, is dark brown ; below, very light brown. The sides are 

 paler, perhaps pale yellow in life, and the color ascends at several points, 

 so as to form cross-bands of moderate width and very well defined. One 

 of tbern crosses at the occiput, and one at the axillae ; between the latter 

 and the groin there are five, nearly equidistant. There is an imperfect 

 one at the sacrum, and there are seven on the tail, one of them imperfect. 

 The coloration of this species is quite unique in the genus in its regularity. 

 The locality of the only specimen is unknown. 



Notes. — I add here that the Plethodon iecanus Cope proves to be a well- 

 marked species of Anaides. The species was described from a young 

 one. Also that a study of all the Amphiumidaa accessible to me, shows 

 that the two and three-toed forms must be referred to a single species, 

 the A. means Gard. 



Is there Reciprocity in Trade? And the Consumption of Manufactured Com-

{Read before the American Philosophical Society, October 1, 1SS6.) 



One of thp chief arguments used by the free trader against the protect- 

 ive system in the United States, is that of reciprocity in trade. Indeed it 

 may be regarded as one of the chief corner-stones upon which their free- 

 trade theory is based. 



Their formula is, that if I do not buy of you, you will not buy of me. 

 And from it they argue that if the people of the United States continue 

 their protective system and refuse to buy their manufactured commodities 

 of England, the English people will refuse to buy anything of them. 



The doctrine, when carried to its legitimate conclusion as they contend 

 for it, is this : We are to repeal our protective laws, so as to enable the Eng- 

 lish to bring into our markets their manufactured commodities and sell 

 to our people free of duty ; and to this extent at least giving the English
