This lamb fetus has been placed in preserving fluid. This can be formaldehyde, isopropyl or ethanol. It is important that glass jars are used, as plastic will be affected by the chemicals over time in the preserving fluid. Note the glass lid and the rubber seal; also the plastic covered metal clasp that has no contact with the contents. It is not known how long the lamb has been in this jar, but it is remarkably well preserved with just a little film of scum on parts on the top of the interior of the jar.The use of such preserved specimens is widespread in teaching students of all ages, veterinary operatives and museums of the composition of certain animals, insects and birds. Any information about an animal — be it photographs, blood, feathers or fur samples — is better than no information at all. But specimens are vital to ground-truth.Large glass jar containing a lamb fetus in preserving fluid.
