and post-historic, and it would probably be much affected by frosts. 



Following out these discoveries, the bases of other buried stones 

 have since been found by probing* the turf with a pointed rod. 



But another question arises respecting certain fragments of a very 

 hard dark quartzite with grains of feldspar. Of this material a large 

 piece was found in barrow No. 4i (Hoare's Map), by Mr. H. 

 Cunnington, in 1872, and more recently — July, 1881 — seven other 

 splinters of it were dug up within the temple. This too, is not a Wilt- 

 shire rock, nor is it like any of the stones at present visible, but judging 

 by the analogy of the soft schist, may we not fairly expect that 

 further exploration will discover the parent stone under the turf? 

 The same remark will apply to some three or four other fragments 

 found within the area, which though they have not been fully ex- 

 amined, are evidently foreign to the country, and as yet unknown as 

 Stonehenge materials. 



Within the three years to December, 1881, four hundred and sixty 

 fragments of Stonehenge rocks found under the turf, in waggon 

 ruts, or in the barrows, have passed under examination. Many of 

 them have been cut for the microscope. 1 



The following specimens were found in three small holes, on July 

 8th, 1881 :— 



Diabase 39 

 Felsite 62 

 Quartzite, with traces of feldspar 8 8 

 Sarsen 9 

 Calciferous chloritic schist 49 

 Micaceous sandstone (altar stone) 5 



1 We are greatly indebted to Mr. Thomas Davies, of the Government Miner- 

 alogical Department, for his kindness in devoting much valuable time to the 

 examination of the specimens mentioned in this paper. They have all passed 

 through his hands, and the descriptions given may be relied upon as accurate.
