closure of the Exhibition, while he was acting as Registrar of 
the High Court, Allahabad, he enquired several times about 
the progress in printing of the present work, more especially of 
the plates, thus showing his interest in this publication. 
Over 800 drawings were copied in about five months. 
Professor Bhim Chandra Chatterji had little time to compare 
the copies with the originals and was, therefore, unable to vouch 
for their accuracy. Details of several drawings, especially those 
made from type specimens, had to be completed. So in December 
1911 I went down to Calcutta and compared the copies of the 
drawings with the originals. Owing to pressure of work at 
Allahabad, 1 could not prolong my stay in Calcutta. So several 
plates were left at Shibpur for details to be filled in. Colonel 
Gage, I.M.S., obliged me by getting this done. In his letter 
dated 29th March 1912, in returning the drawings he wrote 
“ I return herewith the drawings you sent for filling in the details of the 
dissections. They have been gone over by Mr. Ramaswamy and checked in 
every case. It has not always been possible to get precise dissections 
from the Herbarium specimens, as in the case where there is one specimen 
we cannot afford to dissect it. I trust however what has been done will 
prove to your satisfaction.” 
He has placed us under deep obligation by permitting us to 
copy and publish some of the original drawings by Roxburgh 
preserved in the Herbarium in the Royal Botanical Garden 
Shibpur, and to reproduce some of the illustrations given in the 
Annals of it, and also to have drawings made from the type 
specimens in that Herbarium, of some of the plants not to be 
found in publications kept in the library of that institution. 
Our thanks are due to Mr. R. S. Ho'e, F.C.H., F.L.S., I.F.S., 
Forest Botanist of Dehra Dun, for his kind permission to copy 
and publish some of the original drawings of plants prepared 
by Mr. J. F. Duthie, B.A., F.L.S., late Director of Botanic 
Survey, Northern India. 
We are thankful to the publishers of Curtis’s Botanical Maga- 
zine and of Bentley and Trimen’s Medicinal Plants for permis- 
sion to copy some of the illustrations from their publications ; as 
also to the Government of the United Provinces of Agra and 
Oudh for allowing us to copy a few illustrations from the Field
