[Inclosure 1 in No. 447.]

Mr. Wilson to Mr. Day.

Sir: I have the honor to acknowledge the receipt of your communication of the 11th instant, inclosing a copy of a note dated April 7, from the German ambassador, forwarding certain microscopic specimens prepared by the Imperial board of health of Berlin, taken from American fruit at Hamburg and said to be identical with the San Jose scale louse. The preparations in question have been examined, and, while they are mounted in such condition that thoroughly satisfactory determination is impossible, they appear, judging from the visible characters, to be identical with the insect mentioned, namely, Aspidiotus perniciosus.

Respectfully, yours,

James Wilson,
Secretary.
