SCIENTIFIC SERIALS. 



American J ournaloj Science, September. — On the capture of 

 comets by planets, especially their capture by Jupiter, by 

 H. A. Newton. The full paper is not now given. The com- 

 pleted results will be noted in Our Astronomical Column as 

 soon as they are published. — Pleistocene fluvial planes of 

 Western Pennsylvania, by Frank Leverett. Some facts are 

 stated which clash with certain conclusions drawn by Mr. P. 

 Max Foshay in a paper entitled " Pre-Glacial Drainage and 

 Recent Geological History of Western Pennsylvania," which 

 appeared in the November number of the yournal. From these 

 it appears that the obstacles to a northward discharge of the 

 Shenango, Mahoning, and Beaver are, on the whole, greater 

 than those in the way of a southward discharge. In the 

 Monongahela, Lower Alleghany, and the Ohio valleys, the 

 available evidence all indicates southward discharge along the 

 present course of the Ohio from the inter-Glacial period to the 

 present time. — A method for the determination of antimony and 

 its condition of oxidation, by F. A. Gooch and H. W. Gruener. 

 — A method for the estimation of chlorates, by F. A. Gooch 

 and C. G. Smith. — Dampening of electrical oscillations on iron 

 wires, by John Trowbridge. The experiments lead to the con- 

 clusions that (i) The magnetic permeability of iron wires exer- 

 cises an important influence upon the decay of electrical 

 oscillations of high frequency. This influence is so great 

 that the oscillations may be reduced to a half-oscillation on a 

 circuit of suitable self-induction and capacity for producing them. 

 (2) It is probable that the time of oscillation on iron wires may 

 be changed. Only a half-oscillation has been obtained on iron 

 wires, so this law cannot be stated definitely. (3) Currents of 

 high frequency, such as are produced in Leyden jar discharges, 

 therefore magnetize the iron. — Genesis of iron ores by iso- 

 morphous and pseudomorphous replacement of limestone, &c„ 

 by James P. Kimball. The author adduces a considerable 

 amount of evidence showing that such products of epigenesis as 

 siderite and ferro-calcite are, as a rule, products of direct pseudo- 

 morphous replacement of isomorphous calcic carbonate, like 

 limestone, calcite, calc-sinter, calcareous sediments, &c. And 

 the general proposition is therefore advanced that deposits of 

 concentrated iron ores occur far more extensively as pseudomor- 

 phous replacements than is usually supposed. — On the constitu- 

 tion of certain micas, vermiculites, and chlorites, by F. W. 

 Clarke and E. A Schneider. Chemical analyses of several 

 specimens are given. — A further note on the age of the Orange 

 Sands, by R. D. Salisbury. Some new facts are stated in sup- 

 port of the view that the Orange Sand series of sands and
