The section from Itaicy 
to Piracicaba:— A _ recon- 
naissance was made of the 
section from the granite base 
at Itaicy along the railway 
upwards in the series to 
Piracicaba. The following 
rough notes serve to bring 
out the general character of 
the strata below the reptile- 
bearing Permian horizon at 
the latter place and have 
been made the basis of the 
accompanying section and 
sketch map. The station 
numbers are those of the 
kilometer posts along the 
curving and locally recurved 
line of the railway. Notes 
and posts are given in the © 
order in which they came. 
Itaicy has an altitude of 
1,200 M. (1,870 ft.) accord- 
ing to local contour of the 
map.
