no its only russian with pictures and sketchech made by the tsarevitch
Just to clarify - the pictures aren't the Tsesarevich's, actually, but are the work of several artists including the trip's official artist, Gritsenko. The book was translated into many languages at the time it was published, the English version appearing between 1896 and 1900 (in two volumes). All versions of the book are now extremely expensive and are classified as rare. People would have to go to a major research library to access one since copies don't often come on the market (even assuing anyone could afford to pay in excess of $1,000 for one book! :-)).
Recently, parts of the book have been translated into English and re-issued - for example, there was one volume called "Tsesarevich Nicholas in Egypt and India", covering his time in those countries, and another which deals with Siam. They seem to have been based on the original German translation rather than Ukhtomskii's Russian text.
Nicholas did decorate his letters to his mother and his sister with sketches of things he saw. His diary entries for his travels are brief at first (using a pre-printed diary), but when he switched into using what is efectively an exercise book (at the begnning of 1891) he started writing more. Unfortunately most of the entries are the usual account of regiments he reviewed and things he killed; he saves most observation for his letters, particularly those he wrote to his cousin Sandro, with whom he was more frank than with his parents.
Despite these bland diaries, I do believe his travels left a deep imprint on Nicholas, even if they basically confirmed him in ideas he had been taught from infancy about government and Russia's place in the world.
