One other formula for serpentine, MgSi„0 7 (MgOH) 2 H 2 , is 

 reconcilable in part with our data. But such a compound 

 ought to be acted upon more strongly by gaseous hydrochloric 

 acid, and two-thirds of the magnesia should be removable. 

 This limit was not even remotely approached in our experi- 

 ments, although in two cases the one-third limit was definitely 

 exceeded. It is a legitimate question, however, whether there 

 may not be two isomeric serpentine molecules, corresponding 

 to these two formulae ; and this question ought to be kept in 

 view in future investigations. ^

Art. XLII. — On five new American Meteorites y by George 



F. Kunz. 



1. On the group of Meteorites recently discovered in Brenham 

 Township, Kiowa County, Kansas. 



About four years ago, the farmers of Brenham Township 

 ploughed up a number of heavy objects, which they used to 

 weight down haystacks and for other like purposes, as they 

 would have used boulders. It was discovered in March last 

 that these were not common "rocks," but an interesting group 

 of meteorites, numbering over twenty in all, weighing together 

 about 2,000 pounds, and individually from ±66 pounds down 

 to one ounce. They were found imbedded at a slight depth in 

 the soil, which here, for about one hundred feet deep is formed 

 of Pleistocene marl, originally the bottom of an ancient lake ; 

 they occurred scattered over a surface more than a mile in 

 length, principally, however, in a square of about sixty acres. 



What is now Kiowa County, Kansas, five years ago formed 

 parts of Edwards and Comanche counties, and was occupied 

 by large ranges and cattle ranches. Brenham Township, or 

 Township 27, as it was then called, is in the northwestern part 

 of Kiowa County, consists of high prairie with some areas of 

 sand-hills, and has an altitude of about 220 feet above sea-leveh 

 Some drains of the head-waters of the Medicine River and its 

 tributaries, farther south, become ravines and valleys ; and there 

 a gravel occurs, the debris of Miocene " Loup Fork " conglom- 

 erates. But on the high prairie not a stone of any kind is to 

 be found ; hence the ranchmen and settlers were greatly sur- 

 prised at finding heavy "rocks" or stones projecting through 

 the prairie sod. 



Several years ago, Mr. Davis, a lawyer at Greensburg, iden- 

 tified these as meteorites ; and although the farmers had thus
