 I. On an Expression for the effort required to Ascend Planes 

 of Different Inclinations. By Professor Forbes. 



The author states that, whilst it has been pretty generally agreed 

 by authors on animal mechanics that the measure of muscular 

 effort is generally expressed by the weigiit multiplied by the verti- 

 cal height tlirongli which it is raised, it is clear that this cannot be 

 universally true, since, in the particular case of horizontal motion, 

 no vertical height can be obtained ; and, when the ascent is verti- 

 cal, it is very unlikely that the same advantage of ascent should be 

 obtained as at lower angles. 



The author proposes, by a formula, to represent the length of
