the raw products in his well-known work on the Punjab 
products. Dr. Burton Brown, the late Principal of the Lahore 
Medical College, was the reporter on the drugs of the Punjab. 
As a chemist and a botanist Dr. Brown was well qualified to 
properly discharge his duties as a reporter. And up to this 
date, his report is the sole authentic guide to the drugs of that 
province. 
Dr. Stewart, as Forest Officer, in his work on “ Punjab 
Plants,” noticed some of the medicinal plants of that province. 
He freely acknowledged the great help he derived from Dr. 
Brown in identifying many medicinal plants. Dr. Stewart’s 
work is very valuable and, together with Dr. Brown’s Report 
above referred to, is the only work mentioning some of the 
medicinal plants of the Punjab. 
Of the medicinal plants and drugs of the United Provinces 
of Agra and Oudh we know very little. Mr. Atkinson’s work 
on the “Economic Products of the North-West Provinces” 
is the only work treating of the drugs of those provinces. 
The medicinal plants and drugs of the Central Provinces 
and Rajputana have not been properly worked out. It is 
highly desirable that these provinces should receive, at the 
hands oE botanists and medical men, that amount of attention 
which they deserve. 
Thus it will be seen that, although there are many works 
on the medicinal plants and drugs of different provinces of 
India, yet a great deal remains to be done for the drugs and 
medicinal plants of Cashmere, Beluchistan, Sind, Punjab, 
United Provinces of’ Agra andOudh, Behar, Orissa, Assam, 
Central Provinces and Rajputana. Owing to the publication 
of the Fharmacotjraphicu, Indica and Watt's “ Dictionary of 
the Economic Products of India, ” there is not the same diffi- 
culty now to work out the subject which the early laborers 
in this field of research experienced For, not only the 
Flora of British India projected by Hooker has been com- 
pleted, but Floras of most of the provinces of India have 
been in recent years prepared by some of the noted Indian 
botanists- Thus the Bengal Plants by Sir David Prain, the
