	As an outside observer, I must say I agree fully with the ideas 
expressed by Derek Ryan. Internet is an extraordinary tool, must it be 
reduced at the desperate level of commercial TV with its flow of 
information without signification? Ideas, teaching, science and technology 
are far better subjects for me and most reader I assume.

------------------------------------------

	there will be certainly better answers to the questions of Mr. 
Peter C Murray, but I risk some words on the subject as an illustration of 
the remark above. Ideas exchange is the best part of a message forum as 
cryonet.

	So, why not put bodies in a neutral fluid at ambiant temperature? 
First, we are not what we look: at the cellular count level we are a 
package of bacterias. The majority of cells in the limit of our skin are 
not our own componements but bacreria finding here a harbour and an 
ecological niche to grow and reproduce. If we let them in an living medium, 
they will devour us until the last molecule after our death.The 
conservation fluid must so be toxic for bacteria.

	There is the formol solution, but in the long term that product is 
corrosive. I have a friend whose father is immersed in a formol bath for 
some years now.This is an intyermediate solution at best and the quality of 
conservation is far from what can be achevied with liquid nitrogen.

	In the old days, ancien chinesses have used the sap of some 
conifers as conservation agent, it work well for some centuries it seems, 
at least at macroscopic level. When polymerized after some millenia, that 
conservator gives somethig similar to amber, a product protecting the 
molecular structures for millions of years.

	Amber comes from a liquid, the copal, produced by some pacific 
trees: the Dacrydium familly, the Agathis and some Arocarias. I am 
experimenting in France the possibilities of getting a green house culture 
of Agathis and Dacrydium. There is now a field for this activity and the 
first large scale seedling will be done at the end of north hemisphere 
winter.

	I would be very interested if there was a possibility to launch 
such an activity in Australia, 50 000 years ago, before the advent of man 
in that continent, most of the australian forests was made from such 
conifers.I am interested in seeds, cuttings and young plants of these 
species, beyond copal itself if it can be recovered today in the natural 
forest (mostly in Tasmania).

	So the answer turnsinto a question.
Yes, there is a possibility to use chemical preservatives at room 
temperature.
Yes, some folks think about. Yes there is a small activity starting in this 
area.
Now it would be better and faster if the useful trees could be grown in 
their natural environment, so is there any interested people in Australia?
