INTERNATIONAL EXH IBITION, 1862. 283 



CHEMICAL AND PHAEMACEUTICAL PRODUCTS OF 

 THE PROPOSED INTERNATIONAL EXHIBITION 



OF 1862. 



(From the Journal of the Society of Arts.) 



SIR, As the project for holding a great Industrial Exhibition isei. 

 in the year 1862 is likely to be carried into execution, it be- g u ag e sti<ms. 

 comes all those who feel an interest in the movement to offer 

 what assistance they can towards its successful accomplishment. 



From the pages of the Journal it appears that some of our 

 colonies have already taken up the matter, and have resolved to 

 contribute collections that shall fully represent their industrial 

 resources. The execution of this design would probably be 

 assisted, and the resulting collections enhanced in interest and

 and upon their mode of exhibition and the information that 

 should accompany them. If those interested in other subjects 

 would, in like manner, draw up a few notes on points to which 

 it is desirable to direct attention, I cannot but think that useful 

 results would follow. 



The remarks I have to offar will be best arranged under the 

 respective heads of Unmanufactured Drugs, Chemical and Phar- 

 maceutical Products, to which I will add a few observations on. 

 the Manner of Exhibition and Catalogues. 



Unmanufactured Drugs. Substances of this class are not Raw drugs, 

 very attractive objects to the general public, but they are often 

 extremely interesting and instructive to the man of science, as 

 well as to the manufacturer. In the London Exhibition of 

 1851 there was a considerable collection of such products, but a 

 far finer at Paris in 1855. Specimens of raw drugs sent from 

 foreign countries should be carefully packed, so that they may
