I have in hands, now, specimens of bottom from t he Gulf Stream, obtained by Lieutenant Craven, and I can say that they are among the most interesting that I have ever seen. ↗
We sometimes freeze the specimen with liquid nitrogen, which is extremely cold, you know. This is another technique we use now - but the specimens are not alive. ↗
You know, of course, the specimens are not alive. We have to fix them in a fixing liquid formaldehyde and then we have to do a rinsing and then we have to coat them in a thin layer of gold. ↗
