THE FLORAL WORLD AND GARDEN GUIDE 275 



diately they are removed from the ground, or wherever they grow, 

 and suspended with strings in the air. Wh:!re the whole planb is 

 coloured, and several are collected, different parts of each should be 

 varnished, as the moisture cannot evaporate through the varniah. 



PEESE EYING THEM WHEN MOUNTED. 



Fungi are so delightful a relish to insects, that they will soon be 

 devoured if not poisoned. Camphor so soon evaporates as to become 

 a most expensive, troublesome, and, some say, most inefficient 

 remedy ; and its perfume becomes deleterious where in constant 

 use, producing headache, etc., when confined in a room without 

 ventilation. Turpentine and other essential oils become most 

 obnoxious in glass cabinets, their resinous and greasy consistency 

 encouraging the accumulation of dust on the specimens, the glass 

 becomes dull and greasy, and, even if suspended in phials, are liable 

 to ba upset, and cause sad havoc in a collecciou neatly mounted. A 

 solution formed of spirits of wine, corrosive sublimate, and a very 

 small proportion of camphor, is most generally efficacious ; but the 

 use of this will vary almost as much as the plants vary themselves. 

 In the leaf fungi the camphor must be omitted, as it forms a crystal- 

 line deposit. For many of the agarics water must be added, or the 

 mixture will destroy the colour. With the more delicate a coat of 

 varnish auwers admirably, as it at the same time fixes them to the 

 paper, and prevents their being rubbed off. 



I use three ounces of corrosive sublimate at the time (sufficient 

 to poison a little multitude), and have always several preparations 

 in hand; but I should advise amateurs not to manufacture for 

 themselves, as poisons are dangerous tools to play with. 



MOUNTING. 



The larger species must be glued on paper the size of the herb- 

 arium. For this purpose the best transparent glue must be obtained, 

 broken and soaked in cold water two days before using. There can 

 be no rule with such an extensive and variable order as this, but in 

 some cases oil, in others mutton fat, and in others lime-water must 

 be mixed with the glue. For the smaller, a solution of gum acacia 

 should be used, with a little whiting and moist sugar, and four 

 drops, to the pint, of oil of cinnamon. The most delicate may be 

 floated on paper from gum-water, and when dry by exposure to the 

 air, lightly coated with varnisii ; the same process as used for sea- 

 weeds will be useful for many fungi. Leaf fungi will form good 

 practice and good objects for drawing or tracing, mounted between 

 two sheets of glass ; the smaller species should be mounted on small 

 pieces of paper, and pinned on the herbarium paper ; they can then 

 be removed from time to time, as others are added. Both sides of 

 the fungus should be shown when possible. 



Double Lilium Auratum. — Mr. E. Ballen, of the Royal Botanic Garden, 

 Glasgow, has recently had a plant of Liliutn Auratum bearing twelve perfect 

 flowers, and one with ten petals, forming a double row, the inner five being much, 

 broader than the outer ones ; this flower has also ten stamens.
