We report on measurements of the $\Upsilon \mathrm{}\left(1S\right)\mathrm{}$, $\Upsilon \mathrm{}\left(2S\right)\mathrm{}$, and $\Upsilon \mathrm{}\left(3S\right)\mathrm{}$ differential, ${\left(\frac{d^2\sigma }{d{P}_t\mathrm{dy}}\right)}_{y=0\mathrm{}}$, and integrated cross sections in $p\overline{p}$ collisions at $\sqrt{s}=1.8\mathrm{}$ TeV using a sample of 16.6 ± 0.6 ${\mathrm{pb}}^{-1\mathrm{}}$ collected by the Collider Detector at Fermilab. The three resonances were reconstructed through the decay $\Upsilon \to {\mu }^{+}{\mu }^{-}$. Comparison is made to a leading order QCD prediction.
