Too large line spacing with different font size (\tiny) in beamer

Question

When using the \tiny font in slides created with the beamer package I find that the spacing between lines in a wrapped paragraph is too large. (This only happens when mixing fonts within one paragraph.) How do I avoid this?

Minimal working example:

\documentclass{beamer}
\begin{document}

\begin{frame}
  Large Text. And then smaller like so: \\
  {\tiny In mathematics, the method of considering a minimal counterexample (or minimal criminal) combines the ideas of inductive proof and proof by contradiction.[1] Abstractly, in trying to prove a proposition P, one assumes that it is false, and [...] 
  } \\
  (excerpt from \texttt{https://en.wikipedia.org/wiki/Minimal counterexample})
\end{frame}

\end{document}

Answer 1

I found the answer on comp.text.tex: You just need to add \par after the tiny text (and remove the \\) like so:

\documentclass{beamer}
\begin{document}

\begin{frame}
  Large Text. And then smaller like so: \\
  {\tiny In mathematics, the method of considering a minimal counterexample (or minimal criminal) combines the ideas of inductive proof and proof by contradiction.[1] Abstractly, in trying to prove a proposition P, one assumes that it is false, and [...] 
  \par
  }
