126 MR. W. B. HEMSLEY ON THE 
cerning this collection, Hooker and Thomson (‘Flora Indica, 
Introduction, p. 66) say: “The beautiful preservation of the 
specimens, and the fulness and accuracy with which they are 
ticketed, renders this herbarium the most valuable for its size 
that has ever been distributed from India.” All the plants of 
this collection are taken up in Hooker’s ‘ Flora of British India,’ 
though a number of them are not found within its technical limits. 
A separate list of them has also been published by Mr. J. F. 
Duthie, Director of the Botanical Department of Northern India, 
in E. F. T. Atkinson’s work entitled ‘ Gazetteer of the North- 
west Provinces of India,’ vol. x. 1882; and Sir Richard Strachey 
himself contributed an abstract of the Tibetan portion of the 
collection to my paper on Thorold & Bower's and Rockhill’s 
Tibetan plants in the Society’s Journal (vol. xxx. pp. 101-140). 
The Brothers Schlagintweit should also be mentioned, because, 
although they collected little in Tibet, and few of their plants 
have come under our notice, we make use of some of their 
observations on climate and altitudes and distribution. They 
travelled in the Karakorum region in 1855 to 1857,and penetrated 
Tibet, a little to the north of the country visited by Strachey 
and Winterbottom, passing through Gartok and north-westward, 
by way of Yarkand, to Kashgar. Their collections and obser- 
vations were made in the most methodical and detailed manner. 
We shall discuss more particularly their data on the greatest 
altitudes attained by Flowering Plants. 
Dr. Thomas Thomson, whose book of travels is entitled 
‘Western Himalaya and Tibet,’ did not enter Tibet Proper, 
not having crossed the Karakorum range of mountains. The 
explanation of the title is that a part of the North-western 
Himalaya and Karakorum mountains was formerly designated 
Tibet, or Little Tibet, or, in part, Baltistan. We shall have 
something more to say in this connection later on. 
Victor Jacquemont, who travelled in the same region between 
1828 and 1882, also did not get beyond Little Tibet, or Western 
Tibet, as it is usually designated in the ‘ Flora of British India.’ 
Sir Joseph Hooker crossed into Tibet to the north of Sikkim 
by way of the Donkia Pass, and reached and ascended Mount 
Bhomtso, the height of which he estimated to be 18,590 ft. above 
the level of the sea. Flowering piants were collected almost to 
the summit.
