James Fergusson 
History of Architecture in All Countries [PDF ebook] 
From the Earliest Times to the Present Day

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. The History of the Modern Styles of Architecture, published last year, will then form the fourth and concluding volume of the work, or may be considered as a complete and independent treatise, and, like the volume containing the History of Indian Architecture, will be sold separately.
