We present results from our analysis of F160W NICMOS Parallel images .
These data cover \sim 9 sq .
arcminutes and reach 3 \sigma depths of H = 24.3 - 25.5 in a 0.6 ^ { \prime \prime } diameter aperture with integration times of 2,000 to 13,000 seconds .
We derive the first deep H band galaxy counts .
The slope of the counts for H < 20 is 0.31 , consistent with various K-band measurements from the Keck telescopes .
The measured number counts vs. magnitude relation is reasonably well fitted with no-evolution models with a low \Omega value .
The half-light radii of the galaxies declines steeply with apparent magnitude and reaches the NIC3 resoltion limit at H = 23.5 .
Deep ground-based VRI imaging of one NICMOS field has revealed an extremely red galaxy with R - H = 6 and H of 18.8 .
Our analyses of the grism data show that we can reach 3 \sigma flux limits of of 1 \times 10 ^ { -16 } to 2 \times 10 ^ { -17 } ergs/sec/cm ^ { 2 } for integration times of 2,000 to 21,000 seconds .
We have detected a total of 33 emission line galaxies .
The comoving number density is \sim 2 \times 10 ^ { -4 } Mpc ^ { -3 } .
The detected emission lines are probably H _ { \alpha } 6563Å .
Thus , the derived star formation rates , without extinction correction , are 10 - 163 M \odot per year for galaxies at redshifts between 0.7 and 1.9 .
