REVIEWS 701 



put it down again until he has read every page ; and whatever may be the subject 

 the author treats of, the reader is not only interested, amused, and entertained, 

 but finds himself continually reflecting what a delightful person he is making 

 acquaintance with. The subjects of the essays are miscellaneous. Four are 

 personal ; three deal with education ; and science, music, and rural scenes each 

 claim two. The fourteenth is upon dogs and dog-lovers. 



To award the palm would be as unnecessary as it would be difficult. Each 

 seems the best that has been last read, and of course the reader's special tastes go 

 for much ; but if a choice must be made, for this reviewer it would fall upon the 

 essay on Jane Austen. No lover of that exquisite novelist can afford to miss this 

 appreciation of her, many as its predecessors have been. The whimsicality of 

 treating her characters as historical persons, tracing imaginary relationships 

 amongst them, and showing the workings of the principles of heredity, the classifi- 

 cation of them as a natural order into genera and species, the attractive into the 

 dull and the interesting, and the grave discussion as to the species in which any 

 individual is to be placed — all this is as delightful as it is novel. One feels that 

 Sir Francis Darwin is competent to set an examination paper on Jane Austen 

 comparable with that set by Calverley on Pickwick. Is it too much to hope that 

 such a paper may be added to the second edition that will assuredly soon be 

 called for ?

Studies in Indian Helminthology, Nos. 1, 2, 3. By F. H. Stewart, M.A., 

 D.Sc, M.B., Capt. I. M.S. {Records of the Indian Museum, Vol. X. 

 Part III. Nos. 9, 10; Vol. XII. Part VI. No. 18.) 



These three Studies deal respectively with nematode, trematode, and cestode 

 forms. 



No. 1 is a systematic paper describing five new species, and one new variety, 

 of roundworms parasitic in Indian vertebrates, and five larval nematodes, the 

 adults of which are unknown. One free-living form, Oncholahnus indicus, already 

 recorded by v. Linstow, is redescnbed. The new species named are Oxysoma 

 macintoshii from the rectum of Rana tigrina and Bufo stomaticus, Oxysoma 

 kachugce from the intestine of Kachuga lineata, Heterakis macronis from the 

 intestine of Macrones aor, Dacnitis callichroi (two females only) from the intestine 

 of Callichrous macrophthalmus, Airactis kachugce in enormous numbers in the 

 intestine of Kachuga lineata and Spiroptera denticulata Rud. var. nov. minor, 

 (two males) from the stomach of Wallago attoo. All of these species were collected 

 at Lucknow. Of the larval forms one, diagnosed as a Physaloptera, was found in 

 the bladder wall of Bufo stomaticus, the other four occurred in Wallago attoo ; two 

 of these are diagnosed as Ascaris larvae, the other two were not identified. The 

 various species are carefully differentiated from closely allied forms. 



No. 2 deals wholly with the anatomy of Polystomum kachugce n. sp., a trematode 

 from the urinary bladder of a water tortoise, Kachugce lineata, obtained at Lucknow. 

 This is carefully differentiated from the six other species of Polystomum that 

 comprised the genus at the time of the completion of the paper. 



No. 3 records an unsuccessful attempt to infect white rats with the dwarf tape- 

 worm of man, Hymenolepis nana. It is a matter of practical importance to 

 ascertain whether this is the same species as Hymenolepis murina of the rat. The 

 author concludes, perhaps somewhat hastily, from his negative result that these
