Amazon is currently offering G. W. Septimus Piesse’s perfume book for free in the kindle edition. I am not sure how long it is going to be free for, but I suggest getting it!
His perfume book was written in the 1850s and was called “The Art of Perfumery And Methods Of Obtaining The Odors Of Plants”. He thought of scents in terms of music notes, and assigned scents a music note. In the book there are many recipes for the perfumes and other scented products of the time. Many modern day natural perfumers still read his work! I enjoy reading the historic classics since I learn a lot about history and crafting perfumes!
It is also on Project Gutenberg’s website too, they have many different formats available.
