analysis, by means of specified liquids and for the qualitative 

 and quantitative analysis of organic substances. 



In the studies of the second year are comprised those of 

 applied mechanics ; geodesy or land surveying ; meteor- 

 ology and climatology and construction, under which are 

 comprised works of hydraulic engineering and forest 

 buildings. 



The programme of study in Applied Mechanics com- 

 prises:!. The general ideas and principles and general 

 laws of forces and motion. 2. General observations on 

 machines, and the study of their essential organs. 3. 

 Changes of motion of most frequent application in 

 machines, moderators and regulators, passive resistances. 

 4. Transport in general ; forestal transports. 5. General 

 principles of hydrology water gauge of natural and arti- 

 ficial currents; the distribution of waters; modules or 

 appliances for securing uniformity of delivery ; and 

 partidors for securing the same in dividing currents ; units 

 of measurement in the gauging of waters. 6. Calculation 

 of resistances, thickness of dykes of conducting pipes and 

 of steam boilers. 7. Motors : hydraulic motors, steam 

 motors, wind motors. 8. Machines employed for raising 

 liquids, machines employed to transmit gases. 9. Forestal 

 tools and instruments : hammers, machines, mills, cutting 

 tools, and saws. 



In the Cabinet of Mechanics there are various levers 

 and balances ; pulleys, single and combined, and in blocks ; 

 models of simple and differential wheels, and wheels with 

 a catch ; capstans ; cylindrical and conical accumulators ; 

 cog-wheels ; elevator ; fixed crane, and moveable crane ; 

 inclined plane, wedge, shears, circular eccentric ; expanding 

 eccentric ; spiral of transformation ; vertical and circular 

 saw; Atwood's and Morin's machines; apparatus to 

 demonstrate the parabolical movement in the fall of solids 

 and liquids; pendulums, simple & Kater's; endosmo 

 meter of Ducrochet ; V&nturi's apparatus ; apparatus of
