Dear Sir
I return you by today’s post the pamphlet on Salvia, with many thanks to you for your kindness in lending it to me.1 I have read it with much interest. Of course I found that it contained the main facts which I had flattered myself, until informed by you, that I had been the first to observe. There are however a number of small detail in the structure of several species, which add to the perfection of the mechanism, which seem to have escaped the notice of Hildebrand These perhaps it may be worth while to make known.2 Again thanking you cordially for your kindness
I remain | Yrs. Sincerely | W. Ogle.
