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. 

 Asa 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 of 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 Pharmacographiea Indiea 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
