ing upon snow; that is to say it must have fallen during the winter 

 season. 



These are conditions which are entirely fulfilled in the case of 

 the phenomena which have been described. 



The statements of eye witnesses generally show that the meteor's 

 direction was north-west to south-east and if we project a line south- 

 easterly from Middle Lake at which position the meteor is stated to 

 have passed right overhead it will pass through the section where the 

 meteorite was found. 



Again although observers at Muenster have not indicated the 

 data on which they based their conclusion they estimated the elevation 

 of the meteor as it passed north of there at 25 miles. And if we 

 accept Mr. Mutter's estimate of the angle of elevation as it passed 

 Pî'lger as approximately correct and there does not seem any good 

 reason for doubting this as he is a good observer, we get an elevation 

 of somewhere between 30 and 37 miles for the meteor as it passed 

 through a point in the vertical plane projected through Middle Lake 

 and the Huiras farm. 



Thus in traversing one half of the horizontal distance of 15 miles 

 between the two points it had probably fallen about the same distance 

 vertically. And as the trajectory curve would increase rapidly as 

 the meteorite advanced the latter might be expected to fall somewhere 

 about where the Annaheim iron was found. 



Chemical Composition and Metallography 



By H. \'. Ellsworth 



The sample used for the general analysis was taken from a slice 

 about one quarter of an inch thick which had been sawn from near 

 the middle of the meteorite. A rectangular section about one quarter 

 inch square was cut from this slice and drilled in two directions at 

 90 degrees. The borings, amounting to about 10 grams, were well 

 mixed and a five gram amount was dissolved in nitric acid and made 

 up to a litre. Aliquots of this solution were used for the determina- 

 tion of iron, nickel, cobalt, copper and phosphorus. The remaining 

 borings w^ere used for the carbon determination. Two samples of 

 7 or 8 grams each for S and P and one of 10 grams for Cr, V, etc., 

 were made up from the skeleton left by the drilling and from a section 

 cut from the same part of the slice.
