The results of the above table are graphically represented by a 

 •curve in Diagram I, tig. III. It will be seen that there is a great, 

 though not absolutely exact, coincidence between the periods recorded 

 in this curve, and those of the same diagram which exhibit the 

 declination results. 



The form of the temperature inequality for 24 days, see Table VI, 

 is exhibited in Diagram II, fig;. IV. It will be seen that there is a 

 -considerable likeness in form between the various curves of this 

 diagram ; but it must not be forgotten that these curves are in all 

 probability affected by the influence of adjacent inequalities.
