56 MEMOIR OF ALFRED SMEE. [CHAP. VI. 



As this treatise has since been incorporated in his last work, 

 ' The Mind of Man/ I refer the reader to that book for further 

 information on the subject. 



In May he became one of the jurors to that most interesting 

 of all exhibitions the one held in Hyde Park. 



Between the months of May and of September he wrote 

 several long and interesting articles for the ' Illustrated London 

 News,' on various articles exhibited in the Exhibition. Amongst 

 these may be mentioned ' On the Origin of the Forces which 

 have been employed in the Manufacture of the Articles exhibited,' 

 which appeared in that journal on the 10th of May, 1851, as well 

 as another article, ' On the Application of Electricity.' On the 

 17th of May that journal contained the following articles from 

 his pen : ' Light and its Applications ;' ' Electricity ' (Supple- 

 mental Notice) ; ' Dumas's Expanding Model of a Man.' On 

 May 24th, ' Heat and its Application.' On June 7th, ' Mechanical 

 Force.' On June 14th, ' The Food of Man.' On June 21st, 

 'Ibbetson's Castings.' On July 5th, 'Chemitypy, Stylegraphy, 

 and Gralvanography ; ' ' Microscopical Preparations ; ' ' Food of 

 Man' (No. 2); 'Philosophical Instruments.' On July 19th, 

 1 Food of Man ' (No. 3). On August 2nd, ' Wardian Cases.' On 

 August 9th, ' Surgical Instruments.' 



Besides these long articles in the * Illustrated London News,' 

 there are long articles on ' Electricity,' ' Electro-Metallurgy,' and 

 other matters, in the ' Morning Chronicle ' for the 15th and 31st 

 of May. 



The following extracts from the article in the ' Illustrated 

 London News ' on Wardian Cases is here quoted, as it may 

 interest those who are fond of plants, and who are obliged to 

 dwell in a smoky town, to know which can be grown under such 

 adverse circumstances. 



In London (says he) but very few plants will thrive. The Oriental plane 

 rears its head in the heart of the city, in Cheapside, and forms a stately tree. 

 Russell Square and Guildford Street exhibit also noble specimens of this 

 beautiful tree ; yet by coming into leaf late, and shedding its foliage early, 

 it is not so susceptible of those influences which injure other plants. The 

 lime-tree will also partially flourish ; and in the very centre of the Bank 

 two noble and ancient limes shade the parlour from the scorching sun of 

 summer, and yearly cast forth delicious perfume from abundant flowers. 

 With these exceptions, flowers and vegetable structures can scarce be 

 cultivated in London, except with the aid of a Ward's case. Residing in 

 the very centre of the metropolis, we now write with two beautiful Ward's 

 cases before us, which exhibit the most luxuriant foliage. In these cases 

 we have at this moment the beautiful wax-plant, or Hoya carnosa, in
