Magnesian Limestones of Missourt.—Keyes. 387 
ologic sequences in the neighboring localities indicated that a 
part, at least, of the Magnesian limestones were equivalent 
to what in the adjoining states were undoubted Cambrian 
terranes. 
There were, then, three separate and distinct lines of in- 
quiry into the age of the southeastern Missouri rocks. The 
data cerived from any one of these was amply sufficient to 
fix the stratigraphic position of Magnesian sequence beyond 
all reasonable doubt. 
SAINT AUGUSTINE AND HAECKEL. 
EPITOME OF HAECKEL’S “WORLD RIDDLES.” 
PersiFor FRAZER, Philadelphia. 
At a reunion dinner, given by Dr. Beverley Robinson of New York, 
to the survivors of the class of 1862, University of Pennsylvania (arts), 
in celebration of the fortieth year since their graduation, Dr. Persifor 
Frazer read to his classmates the following synopsis of Ernst Haeck- 
el’s ‘“Weltrathsel.” 
At its conclusion the participants, including three clergymen, united 
in a resolution of thanks offered by one of the latter to professor 
Haeckel for the kind greeting he had extended to the class through 
Dr. Frazer. Ed. 
Attenuated jelly fills dimension’s every place, 
Nor cold nor warm nor palpable it co-exists with space.— 
A thrill of condensation, and the atoms first exist. 
They tend to go on shrinking, and this protyle to resist. 
Thus force results and shows itself by radiance and motion; 
The atoms draw together forming islets in the ocean; 
The strain increases, heat ensues, the temp’rature’s appalling, 
The universe is flecked with matter boiling, bursting, falling, 
When, following a partial truce, both halogen and metal 
The calmer realms of boundless space in mated couples settle, 
Still it was hot, and none but pyrogenic families flourished ; 
Volcanoes were the mother’s breasts that baby crystals nourished. 
Some million cycles went their way, the angry clouds abated 
And other, cooler molecules were born from atoms mated. 
First Carbon, with a harem such as only chemists know, 
Began his endless offspring; followed soon by H:O 
Which floated from the lowering clouds that owed to it their birth, 
Until it left uncovered but a third of all the earth, 
Yet ere the earliest vapor from its latent heat had parted 
Had Carbon, the Lothario, extensive families started. 
Anhydrous carbonates, so-called, with beauty soft and placid,
