‘On A BED OF Lower BouLDER-cLAY AT HEATON MERSEY, NEAR 
MANCHESTER. 
A CorRRESPONDENT, who has lately given a good deal of attention 
to a bed of Lower Boulder-clay in Mr. Thorniley’s brick-fields at 
Heaton Mersey, and which is called by the workmen ‘red shaly 
marl,’ writes thus :— 
‘The only published notice I have seen of it is in a memoir “ On 
the Geology of the Country around Oldham, including Manchester 
and its Suburbs,” by Mr. Edward Hull, in which he gives the 
following section :— 
1. Fine white sand, laminated ; two feet. 
2. Layer of peaty matter, composed of the stems and branches of a tree 
with a shining bark, either Birch or Hazel; three inches. 
3. Dark-brown, fine, laminated clay, without pebbles (warp ?); five or 
six feet. : 
4, Boulder-clay, with striated pebbles; five feet. 
Both the sections to be seen there now are rather different. The 
first is from the principal pit:— 
1. White or silver sand ; one foot. 
2. Bluish clay, perhaps the Upper Boulder- clay, stratified and unfossili- 
ferous; six feet. 
3. Red sand and gravel; nine inches. 
4. Lower Boulder-clay, or ‘ red shaly marl;’ seven feet. 
5. Trias; forty-five feet seen. 
The next section is from one of the smaller pits :-— 
. Boggy soil, with branches of trees, most probably Birches ; three feet. 
. Bluish clay, like No. 2 in the above section; four feet. 
. Trias; forty-five feet seen.’ 
Cob 
Our Correspondent adds, that some fossils, derived from the Car- 
boniferous rocks, such as fossil Fish, a fossil Fern (Alethopteris ?), 
and Producta Martini (in limestone), have been found in this par- 
ticular clay-bed. Other fossils shells are said to have been formerly 
found, and a Birch-leaf (possibly, however, from an upper bed). 
Nothing has been found lately.

Tue Hyprovs Minerat PxHospHates.—Some of the hydrous 
mineral phosphates have been lately studied by Professor Church, 
and his results have appeared in the ‘Chemical News,’* under the 
heading ‘Revision of the Mineral Phosphates.’ The following are 
the chief conclusions at which Professor Church has arrived :—
