SHELLS FROM GLOBTGERINA OOZE. 



Fig. I. — Shells from Foraminiferal ooze, brought up in the sounding-tube from 

 a depth of about iioo fathoms, in the vicinity of the Laccadives ; enlarged about 

 forty times. In the natural state the shells cohere together ; but those here shown 

 — which consist chiefly of Glohigerina^ with a few Pulvinulina and OrbuUna — have 

 been separated by repeated washing and careful drying.
