thickness, dipping at an angle of 85°, and striking approximately N.E. and S.W. In 
many places, however, the beds are much contorted. 
(7.) The cliff ceases at (H) and is succeeded by a sandy beach resting on a plat¬ 
form of coarse ferruginous sandstone. 
(8.) The summit of the cliff from (A) to (D) is nearly level and strewn with frag¬ 
ments and nodules of ironstone. Further inland the country is very barren and sandy, 
with scanty grass and a few low shrubs. A quartz dyke-like mass, probably a 
continuation of that at (C), was noticed about a quarter of a mile inland from the edge 
of the cliff. 
(9.) Magnetical observations were taken at positions (I), (2), (3), and (4) on the 
general sketch. A series of the most characteristic rocks and minerals were collected 
by me and are forwarded with these notes.

Appendix B. 
The whole of the geological specimens forwarded from H.M.S. “ Penguin ” have 
been examined by Professor Rucker, F.R.S. Of these, the undermentioned list 
specially refers to positions in the vicinity of Bezout and Baudin Islands of special 
magnetic interest. 
la, 2b, Sc, 4 d. Bezout Island, near Cossack. 
5. Reader Hill, Cossack. 
6. Sand, Cossack—Reader Hill bearing (true) N. 81° E., 7G0 yards. 
18. Broome, Roebuck Bay. 
19. Sand, 3 feet below surface. Magnetic observation spot, Broome. 
21. Sand, from surface of place of magnetic observation, Broome. 
22. Sand, east side of Baudin Island, off Cape Voltaire. 
24. Sand, from magnetic shoal off Port Walcott, in 8 fathoms ; lat. 20° 31' 35" S. 
long. 117° 13' 2" E. 
25. Baudin Island, off Cape Voltaire. 
26. Baudin Island, off Cape Voltaire (basement). 
Of the above list of specimens, Nos. 25 and 26 only are magnetic, their respective 
values of h in C.G.S. units being 0'000217 and 0‘000529.
