3rd. Those obtained from the seeds of grasses are spherical, 
nucleus central, rings concentric, polarise feebly, and have a 
symmetrical cross. 
In mounting starch granules it is advisable to prepare two 
slides for microscopic examination, one in dry cells for the 
study of rings and nucleus, and a second in a solution of 
Canada balsam in benzole for polarised light. 
The Fourth and last Winter Meeting of the season was 
held at the 
SCIENCE SCHOOL IN GLOUCESTER, 
on Tuesday, 27th of February, when a Paper was read by Mr 
Epwarp WerTHERED, F.G.S., entitled “ Further Notes on the 
Geology of Drybrook.” The section known as the Drybrook 
Section is figured in detail in the fourth volume of the “‘Trans- 
actions” of the Club, from the measurements of Mr. Lucy and 
the late Mr Joun Jones. These beds, 149 in number, and 
measuring some 300 feet in thickness, are intermediate between 
the “Old Red Conglomerate” and the “Carboniferous Lime- 
stone Shales,” and consist of a series of light sandy beds, and 
light greenish coloured calcareous Shales, to which Messrs 
Lucy and Jonzs gave the name of “Transition” beds. Mr 
WETHERED stated that he had examined these beds in detail, 
and found the Sandstones to be composed of the constituents 
of granitic rocks, while he believed that the Limestone in the 
Shale was indicative of life, which however had been dissolved 
away beyond recognition by the percolation of water, charged 
with carbonic and vegetable acids. The Sandstones pass into 
a succession of Limestones and Shales; the actual junction 
is, unfortunately, not exposed, but that which is, contains 
abundant remains of life. Special attention was called to the 
bed which the author has named the “ Polyzoa” bed. This is 
a cream-coloured impure Limestone, crowded with stems of 
Poteriocrinus crassus, together with a few Rhynconella pleurodon, 
Rhabdomeson gracile, Fenestrella tuberculata, and Ceriopora 
similis. But the most important find was that of the jaws of
