My dear Dr. Billings,
I have made three more corrosion preparations for your museum. The first is a left human lung [A.M.M. No. 2432 Anatomical Sect.] – vein red, artery blue. It is decidedly better than the one that was broken and which it is sent to replace. It shows the shape of the lung including the curve cut out to make room for the heart. There is an extravascetion[?] at one place but it does not show very much. I have made also a human liver in four colors. Portal vein red, hepatic vein (and cava) blue, artery yellow, bile duct green. It is the best preparation of the kind that I ever made. The only defects are that the acid has affected the green which has unfortunately become very bluish and that the yellow [section of page torn off] I think the preparation [torn] called one of the first class. The kidney which I sent [illegible] had rather a weak injection of the vein. This is perhaps as well as it shows more of the rest but I have now a preparation which is its complement.[A.M.M. No. 2434] Namely a full injection of the vein in blue, the ureter in yellow and no artery.
The lung is sent to replace the other one. The price of the liver is fifty dollars and the kidney is thrown in. The lung and liver are mounted elastically on cushions covered in white silk. I hope you will send a man for them as it would break my heart if the liver were broken.
I intend now to give up corrosions. They take too much time and should be made by demonstrators not professors. A visitor just came in to see the liver. I think it has changed shape a little by its weight. It is worth sending for anyway and if it deteriorates you can pay what you please.
Yours very sincerely,
Thomas Dwight
