On Spores in the Carboniferous Formation of Scotland. 93 



usually contains most of the spores. It should then be dried, 

 and searched under a lens. The spores are easily lifted from 

 the mass with a camel-hair brush, slightly moistened by being 

 drawn between the lips. 



The fine dust which passed through the first sieve must 

 not be thrown away, but allowed to settle, and then examined 

 under the microscope for microspores or other minute organ- 

 isms. Any organisms it contains worth permanent preser- 

 vation may be mounted with Canada Balsam. 



List of Localities feom which Specimens have been 



COLLECTED, WITH THE FORMS OF MaCEOSPORES CONTAINED 

 IN EACH. 



1. Shore, half a mile east of Cove Harbour, one and a-half 

 miles N.E. of Cockburnspath, Berwickshire. 



Position. — Basement beds of the Calciferous Sandstones. 

 In sandy fakes beneath a hard sandstone in which Stigmarice, 

 Lepidodenclra, and Calamite-like plants in fragments are 

 abundant. 



In the spore bed scorpion remains are frequent, and in the 

 plant bed the original of the Eurypterid, Glyjptoscorpius {Cyca- 

 dites) Caledonicus, was found. 



It is noteworthy that in the L^pper Old Eed Sandstone, 

 which occurs only a few feet below, few, if any, plants are 

 preserved ; yet here all at once spores are found in the sandy 

 fakes in myriads, proving the existence of an abundant vege- 

 tation little younger in age than that of the underlying Old 

 Eed Sandstone. 



Contents. — Lagenicula I. 



In line state of preservation. 



2. Old quarry north side of Colinton Eoad, under Craig- 

 lockhart Hill, three miles west of Edinburgh. 



Position. — Calciferous Sandstone Series near the base of the 

 Wardie Shales. In fireclay beneath a shale -like coal. 

 Contents. — Lagenicula I. 



Specimens only fairly preserved. 



3. Shore west side of Billow N"ess. First and second coals 

 west of the Ness, one mile west of Anstruther.
