28 Objects for the Microscope. 



SEEDS. 



Having said a little on the beginning of the seed in the 

 ovary, we shall be prepared to look at the seeds themselves 

 with greater interest. Here also we have an endless variety 

 of beautiful microscopic objects : 



POPPY SEEDS. 



viewed as opaque objects, show a reticulated surface ; 



SWEET-WILLIAM SEEDS, 



oblong and dotted ; 



SILENE, OR STELLARIA, 



beautifully fretted and sculptured 



Foxglove 



St. John's Wort 



Saxifrage 



Geranium 



Anagallis 



Portulaca 



Passion-flower 



Begonia 



Scropularia 



Hyoscyamus. 



Look at all these ; and, above all, get a prepared slide 

 of the exquisite 



ORCHIS SEEDS. 



The'y are like little net-purses, with the seed in them : the 

 loose net is the skin or cuticle of the seed. 



ECCREMOCARPUS OR CALAMPELIS SEED. 



This winged seed is a splendid object for the polariscope. 

 The Eccremocarpus, a beautiful creeper, with large bright- 

 coloured, trumpet-shaped flowers, is a native of the tropics. 



SEED OF CENTAUREA CYAN US. 



The section of the seed of this plant is an excellent object 

 for the binocular. It is common in corn-fields, with small 

 purple florets of the disk, and large bright-blue florets of 

 the ray. Named from the centaur Chiron, who was said 

 to have cured himself of a wound in the foot with the leaves 

 of this plant.
