Subject: Auschwitz
Krematorien I and II [actually II and III]
Our foreman informs us that the floors are to be damp proofed with only one layer, as these buildings are built to be only temporary. One floor is already finished, while the second floor is to be damp proofed in the next few day. We indicate to you as
Agreed price for complete and finished execution or single layer
damp proofing: 1.65 Rmk per square meter
We would ask you, however, to note that for single layer damp proofing of a floor, it is not possible to give the usual guarantee of 2 years, which is understandable, and we recommend you to also cover yourselves by informing the customer.
Heil Hitler!

Rear view of one of the 145 galvanized plates, perforated by hand, which were set into and nailed to the wooden fresh air ducts in the upper part of Leichenkeller 1 of Krematorien II and III, now kept in the PMO “stores”, Block 25. Toxicological analyses were carried out in 1945 by the Cracow Forensic Institute (7 Copernicus street) on 4 complete plates and 2 damaged ventilation orifices found in the ruins of Krematorium II. After scraping the white substance that covered these objects back to the metal, 7.2 grams of scrapings were collected and subjected to two qualitative analyses, which established the presence of cyanide compounds. The report, signed by Dr Jan Z Robel, was written on 15th December 1945 and transmitted to the Examining Judge, Jan Sehn.
