correspond in this situation to the barbs situated on each side of the extremity of an ordinary feather. See Plate 2. Fig: 2 & 3. As the first position of these animals is in the very substance of a primary mus= cular fasciculus, (See Plate 2 fig: 4) it is obvious that the mechanical action of this apparatus will be to aid their longitudinal development whilst new cells are in pro= gress of formation in their interior. For it is scarcely possible that the muscular fibrillae by which they are surrounded can when in action, fail by their friction to urge the two extremities onwards in opposite directions, whilst at the same time, the fibres, by which these entozoa are covered are in conse= quence of their direction preventing the separated ends from regaining their former position, & thus the two ends being always carried in opposite directions without the possibility of a counter movement a general elongation must ensue. This apparatus also, by splitting up the primary fasciculi, will serve a locomotive purpose, & thus enable these animals to reach the cellular intervals between the muscular fibres, where their further development will be completed. That such is the effect of the fibres in question is evident on a careful inspection of some of the fasciculi in which these animalcules are contained, in which a separation of the fibrilla can be
