I have a large figure caption that I want to display. However, it just runs off the page into nowhere instead of onto the next page. What command do I need to fix this? Googling the problem doesn't seem to help, but I probably just don't know what to type in.
\begin{figure}[ht!]
\begin{center}
\includegraphics[width=\textwidth]{Schematic.PNG}
\caption{Really Long Caption Here\label{fig:apparatus} }
\end{center}
\end{figure}

Thanks for your help.
