Bootstrap controls inline alignment?

Bootstrap controls inline alignment?

Other than hacking margins how can I get the following button to display
inline with same height as the select in the following code (instead it's
dropped down on top margin)?

<div>
<h4 class="ilLabel">Select:</h4>
<select class="form-control" placeholder=".input-medium" height>
<option value="all">Default</option>
<option value="s1">Select1</option>
<option value="s2">Select2</option>
<option value="s2">Select3</option>
</select>
<button type="submit" class="btn btn-primary
btn-small">Submit</button>
