On March 15th, Mr. Charles Moore described "the range and 

 structure of the Brachiopoda, with reference to local species." 

 Having alluded to their old name of " lampades " or lamp shells, 

 so called from the peculiar hole through which the pedicle thrusts 

 itself being similar to that in ancient Koman lamps, he enumerated 

 the families of these Mollusca, stated their early appearance in 

 the strata of the earth, and traced their rise, numerical develop- 

 ment and final disappearance through the various formations. In 

 illustration, several beautiful specimens of Crania, Lingida, and 

 Terebratuhe from his own collection were shown, ranging from 

 the Lower Silurian formation to the most beautiful and delicate 

 shells found in our present seas. The Ehynconella, so abundant 

 in the rocks of this neighbourhood, first appears in the Lower 

 Silurian, and passing up through the various formations is found 

 at the present time, though reduced to four or five living species 

 only. The internal structure of these shells, the wonderfully 

 developed spiral coils of the spirifer and loops of the Terebratulse, 

 were described and illustrated by specimens and drawings ; and 

 Mr. Moore concluded with an allusion to his own researches, 

 Avhereby he had been enabled to extend the range of some of 

 these Brachiopoda far higher up in the strata, than hitherto 

 supposed to be possible by other geologists. 



The third and last Lecture of the spring Session was given by 

 the President, on the 12th of April, on " Phosphatic Nodules 

 obtained in the Eastern Counties for agricultural purposes." As 

 the Lecture has been printed and published, chiefly at the expense 

 of Mr. Jenyns, and is now in the hands of the Members, or may 

 be obtained by any who wish for a copy ; it will be sufficient 

 merely to state that the opinion formerly held that these nodules 

 found in the upper Green sand at the base of the lower Chalk 

 were coprolites, was shown to be erroneous. And the opportunity 

 was taken to pay a graceful tribute to the memory of the late 

 Professor Henslow, to whose patient research and scientific acumen 

 agriculturists were indebted for the discovery of the great value
