It is difficult, to say the least, because the lung was inflated just prior to fixation and, although well fixed, retained a spongy consistency and therefore not firm enough to section. I have embedded it in agar without any improvement.

Vacuum embedding should give better infiltration and eliminate the spongy areas. If the lung was not fixed in a vacuum, the spongy areas may be poorly fixed.
