Frozen sections of motor neurones in the thoracic ganglia of Locusta migratoria were treated for thiamine pyrophosphatase activity and for acid phosphatase activity. The TPPase-positive bodies range from 0.5 to 1.25 µ diameter and appear to be the small, membrane-bound inclusions described by Ashhurst and Chapman (1962) in their electron-microscope work; these are the smaller lipochondria of Shafiq (1953). The acid-phosphatase-positive bodies range from 1 to 2.5 µ, diameter and seem to be the lamellar aggregates described by Ashhurst and Chapman that are very similar to γ-cytomembranes, and which are the larger lipochondria of Shafiq. It is concluded that the enzyme content of the γ-cytomembranes is very different in this cell from their content in the vertebrate neurone, and doubt is thrown on the usefulness of TPPase activity as a marker for the Golgi apparatus in invertebrate tissue.
