Results are presented and compared to theory and models on a range of 
topics using part or all of the full HERA luminosity of $0.5 {\rm 
pb}^{-1}$.

{\it Charged Multiplicities and scaled momenta.} The use of the Breit 
frame 
for comparison to $e^+ e^-$ results
 and the choice of scale are explained. 
The benefits of using the hadronic centre of mass frame are shown. Scaled 
momentum distributions are shown for $10<Q^2<40980 {\rm GeV}^2$ and 
compared to MC and MLLA predictions based in LEP fits. Scaling violation 
is presented.

{\it Strange Particle Production.} $K^0, \Lambda$ and ${ \overline 
\Lambda}$ distributions are presented. Compared to expectation there is an 
excess of $\Lambda$'s in resolved photoproduction.

{\it Antideuteron and antiproton production.} Signals identified by 
$dE/dx$ 
are shown. ${\overline p}$ and $p$ rates are equal whereas ${\overline d}$ 
production is suppressed.

{\it Charm fragmentation and} $F_2^{c{\overline c}}$. $D*^+, D^+, D^0, D_s 
and \Lambda^+_c$ signals are presented. Fragmentation parameters are 
extracted and are mostly consistent with $e^+ e^-$ results, with an excess 
of $\Lambda_c$.

{\it Excited charm and charm-strange mesons.} Signals are seen for a range 
of mesonic states. Angular distributions indicate the likely spins. 

{\it Baryons decaying to strange particles} Signals are seen for 
$\Lambda_c(2286), \Lamdba(1520), \Xi(1320), \Sigma *(1385)$ and other 
states.

$K^0_s K^0_s${\it Bose-Einstein correlations.} The formalism is recalled 
and comparison made to $K^\pm K^\pm$. The confusion caused by $f_0(980)$ 
production is described.
