BURROUGHS, WELLCOME & Co., DARTFORD. 



This firm of manufacturing chemists was established upwards 

 of a quarter of a century ago. They are successors to Brockenden 

 who, in 1842, originated compressed medicines in the shape of 

 bi-convex discs. By means of their productions they are credited 

 with having revolutionised the method of administering medicines, 

 and they were also pioneers in the introduction of some of the 

 most notable agents employed in modern medicine. Original 

 scientific research is a marked feature of the work of the firm, and, 

 in fact, the present principal, Henry S. Wellcome, is the founder of 

 two chemical and physiological research laboratories, which, though 

 under separate direction, yet do much scientific work for the firm, 

 and results of the investigations at these institutions are com- 

 municated to the learned societies. Though this survey is more 

 directly concerned with their chemical works at Dartford, which 

 are organised for manufacturing operations on a large scale, yet 

 it may be mentioned that there is a commodious wharf at South wark, 

 which affords valuable transport facilities, and also extensive city 

 offices.
