Reading a paper by RJ Hassett, W Engleman and C Kuhn, III, talking about extramembranous particles in tubular myelin in rat lung (J Ultrastructure Research 1980) I was reminded of how difficult it is to publish a perfect paper. The images in this publication are very nice, and I have used this as a reference in the manuscript i am creating on intracisternal protein in some alveolar type II cells, where I am hunting for clues as to the protein involved in the layering seen in the electron micrographs.  I ran onto this typo (way before the days of “autocorrect” so this was missed to the proofreaders and the publisher)… angels for angles.  Love it.  I am sure there would be a host of posts on typos in my papers.  ha ha… but this was too cute to not bring your attention.
