Theovaria are long strings, lying between the mesen-terial folds: there are twelve pairs of them, com-posed of eggs only. Thread-like organs, chieflycomposed of spermatozoa, appear to be only oc-casionally formed. In this description the point of greatest noveltyis the presence of earthy scleroids of defined formsin the column-wall. That such are found depositedwithin the integuments of certain Echinodermata iswell known; but this is the first time, so far as Iam aware, that they have been discovered in thenon-coralligenous Actinozoa. It is not impossiblethat their presence may reward closer search insome of our native species. Torquay. P. H. Gosse.

The long-continued drought causedall kinds of crops to come to maturity very early,and many of the potatoes, although not properly ripe,had ceased growing before any rain came. Then atthe end of August we had plentiful and refreshingshowers, which changed the brown fields to spring-like green in a marvellously short time. We had,in fact, a second spring. Spring flowers began tobloom again, though it was autumn; plants that hadreally come to their full growth received an im-petus, and began to sprout again; and the potatotubers in the ground sent out buds, and sometimeslong shoots from the eyes, as if newly planted,and in many cases these buds form
