Includes three disposable dissection pans (we could charge you $10 to $20 extra for a single non-disposable pan, but what would you do with it after you've done the experiments) and four specimens packaged in an easy-to-open container:

• frog
• crayfish
• yellow perch
• worm

These animal specimens are initially preserved in the best preservative possible: formaldehyde. Problem is, as you would know if you've done dissections before, formaldehyde is an obnoxious-smelling (as well as toxic) liquid. That's why our supplier has displaced the formaldehyde with water, then displaced the water with a glycol solution using a process that is patented under Patent No. 3573082. You enjoy a very decay-resistant specimen, but without any toxic fumes or messy liquids. Specimens store indefinitely when kept in a plastic bag, but we recommend that you use them within a year of purchase for best quality.

Note: All of the above animals are included in the Advanced Dissection Kit, stock number 250-30.
