Scientific Industries. 487 



In the manufacture .of fine chemicals, alkaloids, and galenicals of 

 exceptional purity, a special and laudable aim is to bring back to 

 this country industries which were slipping away. Many new 

 processes of manufacture of medicinal agents have been developed 

 by their highly qualified scientific workers. Exclusive machinery 

 has been invented and constructed for use in the manufacture of 

 their compressed products and remedial agents which are issued 

 under the " Tabloid," " Soloid," and other trade names, and are 

 characterised by portability and preservability in all climates, as 

 well as by purity. This machinery operates with extreme precision, 

 so as to ensure unique accuracy of dosage, ranging from 1-1, 000th 

 of a grain to one dram and more. Every great British and foreign 

 military and exploring expedition of recent years has been medically 

 equipped by the firm, which has a world-wide connection. The 

 highest awards of the great international exhibitions of the world 

 have been made for the scientific excellence of their products. 



A notable characteristic of the firm in their relations with their 

 employees, who number over 1,300, is the welfare work. A club 

 and institute at the Old Manor House, Dartford, with its beautiful 

 park and buildings forming libraries, reading and writing 

 rooms, assembly rooms, gymnasium, etc., has been founded to 

 promote harmony and social intercourse among the employees. By 

 these means a pleasant resort is provided to encourage mental 

 and physical recreation outside of business hours, by means of 

 music, literary and other entertainments, technical and other 

 classes, athletics, field sports and games. The club grounds also 

 afford facilities for boating, swimming, fishing, and all outdoor 

 sports. 



BURT, BOULTON & HAYWOOD, LTD., SlLVERTOWN. 



When the Victoria Docks were first opened in 1855, this firm, 

 under the name of Burt & Co., settled there, and in 1870 they 

 extended their premises by taking over Prince Regent's Wharf 

 on the Thames. They have an extensive creosoting business, 

 and tar products from practically the whole of Europe are treated. 

 Apparatus which they have for distilling the tar products is such 

 that fractions, whose boiling points differ only by one-tenth of a 

 degree, can be separated. Most of the patent disinfectants on 

 the English market are really manufactured at Regent's Wharf, 

 but the creosoting of railway sleepers is the important branch of 

 their business. 



CHAPMEN, SPENCER, & MESSEL, LTD., SILVERTOWN. 



This firm is the largest of the manufacturers of sulphuric acid 

 in the South of England. The first to produce sulphuric anhydride 

 on a commercial scale by means of a catalytic process, they were 

 able to apply this mode of manufacture to the production of com- 

 mercial sulphuric acid.
