Dear Sir—
I have a strong opinion that no man ought to give a Testimonial, without a full knowledge of the acquirements of the person whom he recommends. Now I do not at all know how far you are acquainted with the intern & extern & of the Vertebrata, or which it is perhaps still more important of the lower invertebrate classes, with the exception of Insects.2
Therefore, though I think very highly of your paper on St Helena,3 & I do not doubt about the value of your Entomology work, I do not feel justified in sending you a testimony, though I I can truly say that you have my good wishes for your success
Pray excuse me & believe me | Yours faithfully | C. D.
