Nature journal rounds up new science books on plants, smell and time
A books-in-brief feature covers four new titles: Margaret Willes's 'Nature's Apothecary' on 100 medicinal plants illustrated from a 1597 herbal; William Tullett's 'Sniff', a history of smell from ancient religion to industrial-era cities; Jim Al-Khalili's 'On Time', which argues time's arrow is physically real; and Stuart Firestein's 'It Could Be Otherwise'.
