wonders why the figures of the muscle fibres of whales were not published in the 'Philosophical Transactions', and hopes that they have not been lost; states that he is working on the fibres of the flesh of insects June 1714 to the Royal Society

Muscle fibres of a cow, of a chicken's breast, of the hind leg of a mouse, and of a leg of a honeybee. Muscle fibres from the breast of a flee, the breast of an ant, and from the flesh of a whale. L. does not find muscle fibres in a mite. 1714-08-21 to the Royal Society

Muscle fibres and their enclosing membranes of the legs of a mosquito and a rose chafer, of a fly, of a crane fly, and of a honeybee. Muscle fibres from the flesh of a cow.

Reply to a letter from the Louvain professor Antony Cink. Theories about the contracting and stretching of muscle fibres and tendons. Comparison with a tightened rope.
