[Vol. XVI. No. 386 



At some points on the surface there is a dirty white incrusta- 

 tion. This, on examination, proved to be carbonate of lime, and 

 is without doubt due to the deposits from the calcareous soil in 

 which the meteorite was embedded. 



The prevaihng color of this iron is dark reddish brown, more 

 inclined to red than others of this fall that we have seen. 



On cutting a section from the meteorite, and treating the pol- 

 ished surface with nitric acid, the characteristic Wiedmannstaaten 

 markings are visible. The fragments of troilite can be plainly 

 seen on the polished surface. The meteorite has about the same 

 arrangement of iron, olivine, etc., as others of this group. Its 

 specific gravity, as obtained from the whole mass, is 4.79; that of 

 the iron and nickel alloy is 7.70; of the olivine (yellow), 3.64 

 {water at 35° C). The volume of the entire mass, determined in 

 the process of obtaining its specific gravity, was found to be 30.6 

 litres. 



Professor E. H. S. Bailey of this university is making a thorough 

 analysis of this pallasite, which be will report in detail at the In- 

 dianapolis meeting of the American Association tor the Advance- 

 ment of Science. F. H. Snow.

A Supposed Footprint in Rock. 



In a field belonging to Mr. J. G. Bemis, in the town of White- 

 field, Coos County, N.H., there is a rock of granite upon which is 

 the impression of a man's left foot. It is a naked foot, and has 

 slipped slightly in passing over the rock when in a muddy condition. 

 No one had mentioned this fact to Mr. Bemis when he bought the 

 farm. The rock is like the rest of the rocks in the place, granite. 

 The place is a very solitary one; and probably no one, till Mr. 

 Bemis came, who is a man of much observation, ever observed it. 



A sketch made by Professor Grundmann, and specimens of the 

 Tock, were shown to Mr. Walter G. Davis, the director of the 

 Meteorological Bureau, Cordoba, South America. He considered 



it very curious, but, not being a geologist by profession, advised 

 its being brought to notice. The place is two miles north of the 

 village of Whitefield, N.H., not far from The Mountain View 

 House, owned by Mr. W. F. Dodge, and near the estate of the 

 Rev. R. G. Waterston (summer residence). A. W. 



BOOK-REVIEWS. 



School Supervision. By J. L. Pickaed. (International Educa- 

 tion Series.) New York, Appleton. 13°. $1. 



The author of this book has had a long experience as superin- 

 tendent of education, first in the public schools, and now at the 

 head of a university. He evidently has a natural aptitude for the 

 work; and this, combined with long practice, has enabled him to 

 produce a work on the duties and usefulness of school superin- 

 tendents which will be very suggestive to those who fill such po- 

 sitions, as well as to educators generally. He maintains in strong 

 terms the importance of good supervision by State, county, and 

 city authorities, and has no difficulty in showing that it has 

 largely promoted the efficiency of the public schools of this coun- 

 try. He devotes comparatively little space to the State and 

 county superintendents, but discusses at length the work of the 

 city superintendent, pointing out its relation to the teachers, the 

 pupils, and the public authorities, with incidental suggestions on 

 every important point. President Pickard fears that the grading 

 and the minute rules for teaching and for the promotion of pupils 

 are making our schools too mechanical, and earnestly advocates 

 leaving greater freedom to both teacher and pupil. The methods 

 of exatnination, too, he thinks require amendment, so that the 

 examination shaU test the pupil's judgment rather than his mem- 

 ory. He favors moral and religious instruction in the public 

 schools, notwithstanding the diflSculties arising from the conflict- 

 ing views of the various religious sects. His mode of presenting 

 his thought is somewhat marred by a too free use of metaphorical
