‘My Dear Mp. Smira, 
‘‘ Since our visit to Abury the other day, I have been looking over 
‘ Abury Illustrated,’ and amongst the Addenda and Notes appended to the 
extra copies (after the Magazine was issued) there are two or three which I 
think might, with advantage, be printed in the Society’s Periodical. I have 
somewhat altered the wording of them, and I have added some remarks by 
Dr. Thurnam on the Kennet Avenue and Sanctuary. As the’‘ vexed question’ 
of the Beckhampton Avenue has been pretty well threshed out in the 
Society’s paper on ‘Abury’ (vol. 4), and in Canon Jackson’s ‘ Wiltshire 
Collections,’ I have not returned to the subject, but have added a note on 
Stukeley’s ‘ Dracontium,’

Tur VaLLuM anp CENTRAL Circies at ABURY. 
The general accuracy of Aubrey’s survey of the great circle and 
vallum (plate ii., fig. 1.), made “ with a plain tables,” is confirmed 
by the elaborate survey made by Mr. Crocker, for Sir R. C. Hoare, 
one hundred and fifty years subsequently. This last, however, 
deviates less from the circular form than that of Aubrey, whose 
error in this particular attaches principally to the east quadrant. 
Stukeley’s plan is an exact circle, and has no pretensions to be re- 
garded as the result of a survey. In comparing the two plans of 
Aubrey and Stukeley, our attention is next attracted by the very 
much larger diameter which Aubrey gives to the remains of the 
northern than to that of the southern circle. It must be supposed 
that either these circles were put in from the eye only, or that by 
some error Aubrey drew them to different scales. His accuracy in 
this respect is impugned by Crocker’s survey, which is altogether in
