would perhaps have been entirely different had the mass been 

 round or thicker, for it evidently moved as straight as possible 

 without rotating at all. That it was found in the hole with the 

 flat side down was due perhaps to the fact that, having lost its 

 impetus, it turned and then fell almost in a straight line. 



As the iron only penetrated to a depth of three feet (90*^"") 

 the earth where it struck must have been very compact and the 

 toYce of the body itself nearly spent. The large Agram iron 

 penetrated 14 to 15 feet (435-450*"'") in a freshly ploughed field, 

 which shows that in the case of that meteorite there must have 

 been considerable force left, the small mass falling very near it. 

 The Mazapil mass, one-tenth of the weight, i^enetrated only 12 

 inches (SO'"").
