Section 2. lutersects the Valley of Malaga opposite Alaurin el Gi-ande,

 a. under tlie Sierra de Cartama indicates serpentine, which is seen 

 under the highly crystalline limestone of this insolated ridge at its 

 W. N. W. end. 



Section 3. Shews the nature of the ground on the western hank of the 

 Rio Guadamedina: the facts analogous to those of Section 1. 



Section 4. Represents the superposition of the high tahle-formed emi- 

 nences near the village of La Pizarra, composed of conglomerate, 

 to the argillaceous or lower hed of the tertiary deposits, which 

 may be followed up the valley from Malaga to this village, 25 

 miles distant. 



Section 5. Shews the position of a patch of tertiary seen on ascending 

 to the Convento de San Anton; 1 . is grau wake- slates ; 2. red 

 sandstone ; 3. secondary whitish-grey compact splintery nummu- 

 lite limestone. 



Section 6. An eminence of tertiary beds between El Castillo del Mar-

 Malaga. 



Section 7. Represents the low preserved tertiary tract that borders the 

 MediteiTanean between Almeria and Cabo de Gata, capped ir-

 the point indicated, have, no doubt, fallen out of decomposed

Sections 8, 9, and 10. Shew the horizontality of the tertiary beds near

 trachytic tuff. 



Section 11. Ts longitudinal, and represents, as from the sea, the high 

 tertiary hill called the Mesa de San Pedro, to the north of this 

 little seaport, and a part of that towards its south. The waving 

 line, under the horizontal ones expressing the tertiary beds, indi- 

 cates the form which the trachytic tuff presents to the spectator 

 from the sea, whose shore the base line is meant to exhibit. 

 Amongst the lower tertiary hills on the right of the section, the 

 fallen masses, composed of alternating strata of semi-opal and 

 coral sand, alluded to in the Memoir, were found ; the subjacent 

 trachytic rocks occasionally come to clay in this tract, as in- 

 dicated. 



Section 12. Is also longitudinal, more or less pai-allel to the shore, and 

 shews the little hollow or ravine in which the mass of pearlstone
