'The special characteristic of the work is the distribution of the course into various decisive Epochs, each Epoch 

 having its Prelude and its Sequel : this the author claims as a novelty, and justly regards as of great value. The 

 prominent parts of each science are well selected, and the whole is written with a vigour of language and a felicity of 

 illustration rare in the treatment of .such abstruse subjects. Thus the popularity which the work obtained was well 

 deserved.'— Pro/. Todhunter.
