By CHARLES S, Boyer. 
In-1886 an artesian well was sunk at the Ponce de Leon Hotel, 
at St. Augustine, Florida. Samples of earth from different depths 
were sent to Mr. Lewis Woolman, who proposes to publish the 
results of his investigations into the geological character of the 
different strata. A layer of bluish clay at a depth of between 85 
and 135 feet was found to contain diatoms, spicules, foraminifera 
and a few polycistinae. Unfortunately, the material was very

the depths of 90 and 120 feet, so that the list furnished below, 
although exhaustive of the material obtained, appears to but indi- 
cate the existence of a richer bed which, it is hoped, may be
