552 ME. F. Ci£APMA]!ir ON THE FOKAMINIFEEA [Aug. 1 898, 



The depth at which the Glohigerina-jnsiTls (samples II-YII) were 

 laid down was judged by the late Dr. H. B. Brady to be about 

 1000 fathoms. Prom the evidence now before me I have made 

 calculations, based on the occurrence of recent forms, and it is 

 satisfactory to know tbat these conclusions coincide exactly with 

 those of Dr. Brady. The great proportion of Glohigerince in the rock 

 points undoubtedly to the fact that the deposit was formed at some 

 distance from the land. The marl is not, however, entirely free from 

 terrigenous material, and a beautifully perfect, doubly-terminated 

 quartz-crystal occurred in one sample. 



The material kindly supplied to me by Mr, Franks has been 

 subjected only to a preliminary examination in view of the present 

 report, owing to pressure of other work, and I am indebted to 

 Prof. Judd for the facilities afforded at the Royal College of Science 

 for working out a part of these results. 



There are several species of the foraminifera which appear to be 

 new, as well as four or five examples of the ostracoda, and with 

 these I hope to deal at some future time, as opportunity permits. 



The following are the details of the samples examined, the 

 numbers of which will be found at the head of the columns in the
