A diagram, possibly incomplete, representing a device that grated apples more effectively in order to make cider. The minutes of the Royal Society meeting record that Hooke mentioned 'an expedient of rasping [...] apples much easier by help of a cylinder covered with tin plates made of the form of a grater' (Birch 3:346). To the manuscript transcription on this page, Hooke has added 'the shap[e] whereof is here annexed', presumably indicating this diagram. The note 'Leaue the space of half a side to insert the figure & description' suggests that a more complex diagram was intended for insertion in the official minutes.
