Anatomy and Development. 
Chatin’s (26) work is an important contribution to and summary of the 
facts regarding Trichinosis. 
On the history of the development of Trichina ; see Owen, J. Anat. 
Phys. xix. pp. 108-110. 
The Tylenchus found by Chatin (25) most closely resembles the 
Anguillula of wheat, but has not the same power of resisting desiccation. 
Beddard’s (23) new form is interesting as approaching, in some cha- 
racters, to the free-living forms; this may be due to its lying in a peri- 
visceral cavity (of Pleurochceta moseleyi ) which is freely open to the 
exterior by a series of large dorsal pores. 
Cobbold (27) fiuds in Simondsia a rosette-shaped uterus which he thinks 
comparable with the uterus of Sphcerularia. 
The male organs of Oxyuris and the female of Ascaris are described 
in detail by Raillet (35) and Van Beneden (24). 
Megnin (32) thinks that embryos of Nematoid worms may give rise 
to a special form of tuberculosis.
