The section from Itaicy 

 to Piraeicaba : — A recon- 

 naissance was made of the 

 section from the granite base 

 at Itaicy along the railway 

 upwards in the series to 

 Piraeicaba. 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.
