To Isidoro Dell’Oro   2 May 1873

May 2. 1873

Sir

I am very much obliged to you for your kindness in having sent me the account of the silk-worms, which I have read with great interest.1

I quite agree with your remarks on the benefit derived from a change of conditions.2 You do not state that you require the Gazette to be returned, & I will therefore keep it unless I hear to the contrary—3

Dear Sir | yours faithfully & obliged | Ch. Darwin

CD refers to Isidoro Dell’Oro’s ‘Sericulture, and silk in Japan and in Europe’, London Gazette, 17 January 1873, pp. 169–75.
Dell’Oro believed that a change of locality, climate, and rearing practices would help save the eggs from the superior-quality yellow silk cocoons found in Italy, which were subject to a disease (pebrine) that caused larval atrophy; to test his views, he took yellow cocoons from Italy to Japan (London Gazette, 17 January 1873, pp. 172–3.
There is no copy of the article from the London Gazette (see n. 1, above) in the Darwin Archive–CUL.
