 careous chloritic schists " and one of the diabases were taken from 

 the stumps of stones discovered by Mr. H. Cunnington in 1881. 



In studying the great mass of materials collected by Mr. Gowland 

 I have received invaluable assistance from previous investigators 

 of the subject. Professor N. S. Maskelyne very generously placed 

 at my disposal his original sections made from fragments chipped 

 from the monoliths ; while Dr. H. P. Blackmore allowed me to 

 have the loan of the fragments themselves, which are preserved in 

 the Salisbury Museum. Mr. Fletcher, of the British Museum, 

 permitted me to inspect the specimens sent by Mr. William 

 Cunnington to Mr. Thomas Davies, with the sections made from 

 them, while Mr. Teall gave me further information concerning 

 the sections examined by him. I must also mention the great 

 assistance I have received from the Bibliography of Stonehenge 

 and Avebury," 2 which has been so carefully compiled by Mr. W. 

 Jerome Harrison.

The series of fragments selected by me from the great collection 

 made by Mr. Gowland fall into the following classes. The com-
