Professor C. U. Shepard on Meteorites. 249 



under the hole there appeared a depression in the grain, 

 which led to an examination that resulted in the discovery 

 of the stone. The Judge inferred that the stone had fallen 

 through the roof, as its size was too great to have allowed 

 its admission into the bin along with the grain, which was 

 raised by means of elevators. He also supposed it to have 

 been of atmospheric origin, as the mill was four storeys high 

 and as the nature of the stone was unlike any of the mineral 

 productions of the region, the rock in situ at Waterloo 

 being the Seneca limestone. He was not positive whether it 

 was found in 1826 or 1827. The stone was divided for Dr 

 Hale, President of Geneva College."* 



The specimen presented me by Prof. Root had been left 

 for upwards of twenty years in the garret of Judge Watkins, 

 where it appears to have been mistaken for something edible 

 by the rats, who have left numerous markings of their incisor 

 teeth upon its surface. Indeed, in colour and texture, it 

 nearly resembles common rhubarb. Its colour is light buff 

 or yellow. It is slightly coherent, and may easily be crushed 

 between the fingers. Its sp. gr. = 2*30. But a small portion 

 of the original crust remains, which is reddish-brown. The 

 stone contains in small quantity, blackish particles attracted 

 by the magnet. A surface produced by being cut with a saw, 

 shews waved parallel lines of greater hardness than the rest 

 of the stone. It consists of
