Field Meeting, 22nd June, 1889. 
BRICKET WOOD AND MUNDEN PARK. 
Arriving at Bricket 'Wood Station by different trains, tbe members 
attending this meeting formed two sections; the first, led by Dr. 
Morison, walked through part of the wood and over the scrubs to 
the brick-fields where the boulder-clay is worked, and the second, 
under the guidance of Mr. Hopkinson, strolled more leisurely through 
the wood, botanising, and then took the road across the scrubs 
direct into Munden Park, joining the first section at Munden House. 
Here the members were very kindly entertained by the Honour¬ 
able Mr. and Mrs. Holland Hibbert, who, after refreshments had 
been partaken of, showed and explained the many interesting and 
valuable objects of interest which make their house so well worth a 
visit. They then conducted the members in detachments over their 
beautiful grounds, through which flows the Eiver Colne, adding 
much to their picturesqueness. 
Before leaving, a vote of thanks to their host and hostess was pro¬ 
posed by Mr. Hopkinson, who alluded to their kindness in inviting 
the Society after they had twice before prepared for visits which had 
been prevented by wet weather. 
Field Meeting, 29th June, 1889. 
TOTTERNHOE AND IVINGHOE. 
The Chalk Eock, the top bed of the Middle Chalk, having been 
seen at Boxmoor on the 18th of May, this field meeting was arranged 
to enable members of the Society to examine another hard and 
fossiliferous bed in the Chalk—the Totternhoe Stone—which occurs 
near the middle of the Lower Chalk; and also at the same time to 
gain some knowledge of the peculiar features of the north-western 
escarpment of the Chalk. 
The meeting was held in conjunction with the Geologists’ Asso¬ 
ciation, and was under the direction of Mr. Hopkinson. The 
members of the two Societies met at Stanbridge Ford Station in 
the morning, commencing here a walk of twelve or thirteen miles, 
two wagonettes conveying most of the ladies. 
Totternhoe Knoll, on which is a British earthwork, was first 
ascended. The view from the summit, 524 feet above sea-level, is 
very extensive in clear weather, but to-day, though fine and warm, 
moisture in the air caused a haze which circumscribed it. When 
all were assembled, the Director said that he would attempt to give 
an outline of the principal geological features of the surrounding 
country, and would then ask others present, who had made a 
special study of the district, to fill in details. 
On a clear day, he said, there would be seen in the distance on 
the north-west a range of hills gently rising from the almost level 
plain. These hills mark the outcrop of the Lower Greensand, 
rising from under the plain, which consists of the clayey beds of 
the Gault and of the Chalk Marl, the line of division between these
