Under such circumstances, if they possess any points in common, men are rapidly drawn together ; and there is certainly a wonderful keenness of enjoyment in such intercourse, contrasting as it does so completely with the isolation, often experienced for months or years together, by men whose work lies in such remote regions as that which Himin Pasha has made his home.

Perhaps the thing that struck me most about Dr. oe during my stay with him was the genuine interest he took in scientific work. Readers of this volume will not have turned over very many pages before they discover that he thought no amount of trouble too much, in order to find some new plant, or make a fresh discovery about the growth of a tree or the habits of an animal.
