This letter was written by George Grey Butler (son of the famous social reformer Josephine Butler) to Ernest Aves in 1889. For a time he lived in Toynbee Hall, the famous University settlement in East London. I would be grateful if you can either translate this letter or given me some idea what it might say. I will, of course, acknowledge any assistance. NB: I translated this from the original and have no familiarity with Latin so it might contain some/ a lot of mistakes- oops.
4th June 1889
Cari et rari Aves
Magnam voluptatem habebo istis tabulis quarum mentionem fecistis in otnan dam Toynbeiam Aulam conficiendis negativis, jam in manus cuiusdam sollertis photographi depositis, non longo intervallo amplioris magnitadims (magnitudis) positwas (positis) gigment, quas in vestras manus tansmittere properabo.
Oro ut caninoe haic ephistoloe verniam
George Grey Butler
Many thanks to Greg Jenner, Tim Whitmarsh and Llewellyn Morgan for helping me disentangle this letter, which apparently is about Butler developing some negatives for Aves .
