Página 175 - The study of the larger fungi has been to me one of the greatest pleasures of my life: when all things else have failed, this has never failed ; it has taken me into the pleasantest of places and amongst the best of people. Had it not been for fungi, I should have been dead years ago ; often tired, jaded, and harassed with business matters, a stroll in the rich autumn woods has given me a new lease of life.
Página 112 - Make a cold saturated solution of corrosive sublimate ; put it into a deep wide mouthed bottle, then take the slug you wish to preserve and let it crawl on a long slip of card. When the tentacles are fully extended, plunge it suddenly into the solution ; in a few minutes it will die, with the tentacles fully extended in the most life-like manner, so much so, indeed, that if taken out of the fluid it would be difficult to say whether it be alive or dead. The slugs thus prepared should not be mounted...

Had it not been for fungi, I should have been dead years ago; often tired, jaded, and harassed with business matters, a stroll in the rich autumn woods has given me a renewed lease of life." Another, the illustrious Fries, of Sweden, writes as follows when over eighty years of age : " Now in the evening of my life, I rejoice to call to mind the abundant pleasures which my study of the more perfect fungi, sustained for more than half a century, has throughout this long life afforded...

Some slugs appear to be more susceptible to the action of the fluid than others ; and it generally answers better with fullgrown than with young specimens. But if successful, the specimens are as satisfactory as could be desired ; and even if unsuccessful, they are a great deal better than those preserved...
Página 112 - As regards the internal shell, it may be obtained by making a conical incision in the shield, taking care not to cut down upon the calcareous plate, which can then be removed without difficulty. The animals can only be conserved by keeping them in some preservative fluid ; but the great object to keep in view is to have the slug naturally extended. Most fluids contract the slugs when they are immersed in them. The slugs should be killed whilst crawling, by plunging them into a solution of corrosive...

Página 57 - ... with like result. If we are destitute of any apparatus, and brimstone lucifers for the purpose of suffocating our captures under an inverted tumbler cannot be obtained at some roadside inn, we must fall back on the barbarous practice of pinching the thoraces of such as cannot be carried home in boxes. At home we shall find the laurel jar and ammonia bottle the most useful. The former is made by partially filling a large wide -mouthed bottle or jar with cut and bruised dry leaves of young laurel...
Página 13 - It is a lovely place, and at the side Rises a mountain-rock in rugged pride; And in that rock are shapes of shells, and forms Of creatures in old worlds, of nameless worms, Whose generations lived and died ere man, A worm of other class, to crawl began.
Página 58 - Several of the smaller vessels were seized and twisted, but without inducing any laceration or "refoulement" of their inner coats, being simply held between the thumb and fore-finger of the left hand, while the torsion was effected with the forceps in the right hand. The healing of the wound was very slow, but ultimately complete.
