I am directed to thank you for your letter of March 19th, and for your kind offer of casts and photographs of Thylacopardus (Owen), but these will not answer the purpose in view, and we will therefore not trouble you to send them. I am writing to the Department of Mines upon the matter. Thanking you again for your courtesy,
I have the honour to be, Sir, your obedient servant.
