eral other effigies, and thirty or forty mounds 

 and embankments, on the same terrace with 

 the birds, which have been removed in grad- 

 ing streets and lots. 



No. 3 is near Richmond Station, on a terrace 

 about twenty-four feet above the river. It is 

 seventy-six feet in an air line from tip to tip of 

 the wings ; and the body, with head and tail, 

 is forty-four feet in length. The bod} T , to the 

 first joint of the wings, is fifteen inches in 

 height. Formerly a number of ordinary 

 mounds existed in the immediate vicinity of 

 this effigy. 



No. 4 is situated near the village of Dakota, 



be enumerated from all the published surveys 

 together. 



The effigies surveyed by myself, in addition 

 to the twenty-five in Minnesota, are one in 

 Iowa, and ninety-six in Wisconsin, — a total 

 of a hundred and twenty-two to the present 

 time. On critically examining their delinea- 

 tions, very important differences in class and 

 style from those farther east, portrayed in 

 Lapham's work, are discernible ; so that one is 

 irresistibly drawn to the inference, that, before 

 generalizations of value can be made, ten times 

 the number of facts now recorded must be 

 gathered together. Unfortunately, however, 



upon a terrace about thirty feet above the river, 

 and is in the midst of nineteen ordinaiy 

 mounds. Its length is a hundred and ten feet, 

 and the centre of the head is two feet and a 

 half in height. It undoubtedly represents a 

 fish. This is the first case that has been dis- 

 covered of a fish with fins. 



In the limited territory hitherto examined 

 \>y me in south-western Wisconsin, it would 

 seem, from the numerous ruined effigies, that 

 there formerly existed hundreds of such works. 

 Judge Gale of Galesville estimated that there 

 were fully one thousand effigies in the southern 

 part of Trempeleau count}' alone ; and, from 

 my own observations, I should say a like esti- 

 mate for Vernon and Crawford counties would 

 be rather under than over the truth. Taking 

 Judge Gale's estimate for Trempeleau county, 

 and reducing it one-half, there would still re- 

 main more effigies in the one county than can 



that fell destroyer of antiquities, the plough, 

 annually narrows our field of research. 



In conclusion, something might be said on 

 the question of the relation between any relics 

 contained in this class of mounds and their 

 shapes. The fact is, however, that little, if 

 airy thing, has been understandingly done with 

 a view to ascertain their contents. The few 

 effigies opened along the Mississippi have 

 shown relics and forms of interment similar 

 to those of the common burial-mounds of their 

 neighborhood. T. H. Lewis. 



RICHET ON MENTAL SUGGESTION. 



In the Revue philosophique for December, Mr. 

 Richet gives an account of some experiments in 

 mental suggestion, and attempts to estimate their 

 value by means of the theory of probabilities. Men-
