chemistry/biology/forensic science books for sale

I am selling my sons text books, if any one would like more info then please message me. all mint condition.

Hi, this is Aron, Karen's son. I graduated as of 2014 so I have no more use for my textbooks, therefore I'm selling them on to whoever may find use for them.

The chemistry textbooks I have are as follows:

--principles of analytical chemistry, 2000, 5th ed, Fidield and Kealey
--Chemistry, 2010, 4th ed, Housecroft and Constable, Pearson

Some of the more specialised textbooks which cover more analytical and toxicological information include:

--The chemistry of explosives, 2011, 3rd ed, Akhavan, RSC Publishing
--Clarke's Analytical Forensic Toxicology, 2008, Jickells and Negrusz (editors)

And just on the side there are two books I found very useful for writing dissertations:

--Palgrave Study Skills; How to write your dissertation, Bryan Greentham
--Writing your dissertation, 3rd edition, Swetnam and Swetnam

We live in the York area but are willing to post if you are interested.
Kind regards,
Aron
