The general formula for the globes takes the form of the following equa- 
tion,

P being the collapsing pressure in Ibs. per square inch; D=diameter ; 
t=thickness of glass. Similarly, putting L=length, the formula for the 
cylinders is

P= C x na

which is precisely similar to that for iron tubes. 
Report on the Marine Fauna of the South and West Coasts of Ireland. 
By X%. Percevat Wrieat, M.B., AB. PLS. MRIA., Di- 
rector of the Museum, and Lecturer on Zoology, University of 
Dublin; and J. Reay Greene, A.B., M.RIA., Professor of 
Natural History, Queen’s College, Cork. Part I. (1858). 
At the last Meeting of the British Association, a Committee consisting of 
Drs. E. Perceval Wright, Melville, and Kinahan, was appointed to investigate 
the marine Zoology of the south and west Coasts of Ireland. 
Professor J. Reay Greene and Dr. Carte of Dublin were subsequently 
added to the Committee. 
The region marked out for their observations extends from Carnsore Point 
in the Co. of Wexford, to Gweedore Bay in the Co. Donegal, and embraces a 
coast line cf several hundreds of miles. It was evident that so vast a district 
could only be investigated by the labours of several years, and hence, on 
mature deliberation, the Committee determined to devote themselves and 
the money grant placed at their disposal by the Council for 1858, to in- 
vestigate parts of the Cos. Waterford, Cork, and Kerry ; reserving the Coasts 
of Clare and Galway for the next ensuing summer, and those of Mayo, 
Sligo, and Donegal for another year; hoping, at the expiration of this period, 
to be able to communicate to the British Association a Report, which, with 
the joint Reports from the North of Ireland and Dublin Bay Dredging Com- 
mittee, will enable us to draw up a final Report on the Irish Marine Fauna, 
which shall be entitled to act a second part to that by the late Professor E. 
Forbes ‘On the investigation of the British Marine Fauna,” published in 
1850. 
Such being our intention, we wish it to be understood that the present 
Report is merely provisional, and that we refrain from deducing any theories 
from the facts observed, until we have the entire district examined. 
Early in July 1858, we proceeded to investigate the first selected region, 
and a list of the stations from which the coast at each side was explored is 
given, i. e. 1. Carnsore Point; 2. Saltees; 3. Hook Head; 4. Dunmore; 
5. Tramore; 6. Youghal; 7. Cork Harbour; 8. Kinsale; 9. Rosscarberry ; 
10. Castletownsend; 11. Baltimore; 12. Cape Clear Island; 13. Skull; 
14. Crookhaven; 15. Glengariff; 16. Berehaven; 17. Ardgroom; 18. Ca- 
hersiveen; 19. Valentia; 20. Dingle; 21. Ventry; 22. the Blasquet Islands. 
Several portions of this district had from time to time been investigated
