PAPER LIGHTS were never much em- 

 ployed, and, since the introduction of 

 \Yhitney 's and Other compositions for 

 rendering cloth semi-transparent, are 

 still less likely to he employed. Car- 



i tridge paper is the hest for the purpose. 



I It should he damped hefore it is nailed 

 upon the frame, because when dry it 

 hecomes taut. It may then be painted 

 over with boiled linseed oil, in which a 



I little white lead has been incorporated. 



| In nailing on the paper, a strip of tape 



; should be placed between the heads of 



the tacks and the paper, to check the 



tearing to which the paper is so subject.

PARASITIC PLANTS are such as derive 

 their nourishment from other living 

 plants by rooting into their sap-vessels. 

 Examples are the Mistletoe and Dod- 

 der, which attach themselves to the 

 stems and branches of some plants ; 

 the Hypocistus, and the Orobanche or 

 Broom Rape, affix themselves to the 

 roots of others. The minute fungi 

 which constitute the mildew are also 

 parasites. There is some doubt whether 

 the Ivy is at all parasitical ; but whether 

 it derives nourishment or not from 

 trees, it certainly checks the respiration, 

 and prevents the free access of light 

 and air to tbose upon which it attaches. 

 The orchidaceous plants, Avhich grow 

 upon dead wood as readily as upon 

 living timber, are not parasites.
