stars. This problem, too, is discussed in the light of the discoveries at Tulse Hill. From the simple but beautiful harmonic system of hydrogen lines which characterizes a white star like Vega, we learn how we pass to the more developed star of a solar type, like Capella, and thence to Arcturus, and Belelgueze, which indicate a still later stage of development. At least this is the theory of the author. Aside from its great theme lucidly discussed the book deserves to be upon every library table as a superb specimen of book- making. For once, beautiful truth is promulgated in fitting guise. Lady Huggins is an artist and archaeologist as well as an astronomer, and the initial letters of the chapters are illuminated with original sketches and designs from quaint old manuscripts, which make the book artistically as well as astronomic- ally worthy of the prize which it re- ceived from the Royal Society as the most distinguished contribution to the scientific literature of the year.


Anyone who wishes to gain a fairly adequate idea of what experiments on living animals have accomplished for the welfare of the human race and of other animals as well, can now do so by reading 'Experiments on Animals,' by Stephen Paget. Mr. Paget has col- lected evidence showing the part that animal experiments have played in the progress of physiology, pathology, bac- teriology and therapeutics. He has not ventured to offer opinion or even state- ments unsupported by exact and veri- fiable facts. A large part of the book's space is filled by original quotations from scientific workers, from Galen down to the recent students of the malaria parasite. It shows plainly that knowledge of the processes of life in health and disease has throughout de- pended on experiments on living sub- stances. Mr. Paget's book is not de- pendent for its interest solely on the laudable curiosity to know the worth of animal experiments. For these have

been so important in the science of medicine that their story is at the same time the history of a great number of medical discoveries. There is, too, a freshness and biographical interest in the quotations from the famous -past and present students of medical science which makes them very readable.


In his "Familiar Fish, their Habits and Capture," Mr. Eugene McCarthy has put forth a readable volume which doubtless will prove popular among the disciples of Izaak Walton, for it is es- sentially a book for anglers, written by an angler of experience. A prelimi- nary chapter, devoted to fish-culture, dwells on the destruction of eggs and fry in nature and the necessity for arti- ficial measures. It is a fairly good gen- eral outline of the subject, although some of the methods described are ob- solete. The many breeders of orna- mental fish will wonder whether the au- thor is intentionally facetious in stating that the "famous double-tailed goldfish frequently seen are raised in Japan, and are produced by violently shaking the eggs in a pan."

About a third of the book is devoted to brief accounts of the distribution, food, habits and peculiarities of the fresh-water fishes most sought by an- glers, the salmons, trouts, basses and pikes naturally receiving most atten- tion. The remaining pages deal chiefly with the description of angling para- phernalia and methods, camping, boat- ing and useful data for sportsmen. By far the best chapters are those treating of the ouananiche and its capture, as the author writes from ample experi- ence. He gives it first rank among our game fishes and holds that "pound for pound the ouananiche can greatly out- fight the salmon, and none of the fresh- water fishes can equal it in this respect; the black bass approaches it the near- est but never equals it."

The volume is freely illustrated with fishing scenes, angling apparatus and twenty-five full-page figures of fishes,
