A SE

meridian point on the horizon, it will be found on calculation that the 
Sanctuary at East Kennet is 47° E. of that point, corresponding very nearly 
with the above figures. It may be conjectured, therefore, that the position 
of the minor temple at East Kennet, and of the end of the avenue at Beck- 
hampton, was determined by the position of the rising and setting sun in 
reference to the greater temple at Avebury at the time of the winter solstice 
(Dec. 21.) The curve in the avenues may have been suggested both by the 
conventional forin of the serpent and by the apparent course of the sun.” 
May we not hope that in course of time Archeological 
research will place the object for which Avebury and Silbury 
were erected on as firm a basis as our knowledge of where 
the Sarsens stones were derived from ? 
The members drove back to Swindon, and became dis- 
agreeably conscious of the force of the wind when it is blow- 
ing a gale over the Marlborough Downs. 
Time only admitted of a cursory examination of the 
Swindon section, and it was resolved that it should form one 
of the meets for next year. Dinner at the Goddard Arms. 
The first Winter Meeting was held on Tuesday, the 25th 
November, when our Hon. Secretary gave a paper on— 
“ividence of the process of the formation of the Inferior 
Oolite deduced from Microscopic Examination,” of which the 
following is a resumé :— 
He referred at some length to the structure of the oolitic 
granules, which he contended were, in the main, of organic 
origin, and not concretionary, as generally supposed. This was 
illustrated by micro-photographs, in which some of the granules 
showed a tubular structure around nuclei. These Mr Wethered 
explained were the tubuli of the very interesting organism or 
plant known as Girvanella. The nuclei of the oolitic granules 
consisted of fragments of calcareous organisms, and round these 
the Girvanelle collected, forming a granule. In some granules 
this tubular structure could not be seen, and then the 
_ granules showed either a granular or a crystalline structure. 
A concentric arrangement around the nuclei was sometimes 
Seen, but not often. In these instances it might be contended 
that the chemical or concretionary origin of oolitie granules 
might be maintained, and possibly this might be so in some
