I am a histologist and I am currently delving into the area of facial development of vertebrates (specifically the origin and route of the nasolacrimal duct). Thus far, I have published rabbit, lizard and snake. I have Mongolian gerbil in prep and Albatross and Alligator in the wings with Coqui frog lined up. I am preparing my sabbatical proposal, and I am trying to find where I can get more of such series. Any suggestions/volunteers for potential sources?
