the medium of the Register , the best method of preserving Walnuts in perfection.

Promised Paper on Vegetable Physiology.—I beg leave to ask Quercus, 
when we may expect his paper on Vegetable Physiology, to appear in the Regis¬ 
ter. Also, when Mr. Murphy intends to continue his observations on plants, 
which entrap insects. Also, would the Conductors give me the promised infor¬ 
mation respecting the Passifiora ? F. F. Ashford. 
On Taking Impressions of Leaves on Paper, &c. —A short time ago, I 
saw the impression of some leaves on paper; it appeared to me the colour was 
laid upon the leaf, and then pressed upon the paper, as the veins of the leaf were 
so distinct. Pray, can you or any of your correspondents imform how it is per¬ 
formed ? What is the best book to assist a young beginner in learning to draw 
plans of gardens, fruit and flowers ? 
Hackney. H. C. 
Manchester Gigantic Celery. —I shall feel obliged, if you will inform me 
of the name of the Large Red Celery, mentioned in one of the early numbers of 
the Register. Also, where I can obtain the seed in London. W. G. 
The name of the sort our correspondent enquires about, is the Manchester Gi¬ 
gantic. Whether it can be obtained in London or not, we are not certain, but 
we should think the seed of so valuable a sort, is in possession of some of the 
London Nurserymen : what we possess of it was received from Manchester. 
Rhubarb Plants.— The plants of Rhubarb should not be allowed either to

weakened. J. Hovvden.

in polishing the finest marbles, and may be used with equal success in polishing 
shells. M. 
Preserving Apples.— Will you have the goodness to mention in a few 
words, what you consider to be the best made of keeping apples ? if on shelves, 
should there be bars to admit air under them ? and what is the best covering for 
them ? I have been told, that in America they cover them with a single cotton 
or linen cloth, which protects them from their severe frosts. Should light and 
air be admitted into the apple chamber ? , A. B. 
An answer in our next. Conductor. 
Witty’s Patent Furnaces.— A subscriber would be much obliged, if you, 
or any of your correspondents, who have seen any of Witty’s Patent Smoke 
Consuming Furnaces for Hot-houses, would give a'description of them. I think 
it would be generally interesting to your readers. I should like to hear also, if 
you or any of your correspondents have tried the quicksilver water, recommend¬ 
ed by Speechley, for the destruction of insects on the pine, and whether it has 
been found successful.
