LITERARY NOTICES.

of America are in the Gulf of California, but 

 pearls are also found in shells of the unio, 

 mussel, common clam, and other shell-fish 

 all over the United States. Within one year 

 they have been sent to the New York market 

 from nearly every State in the Union. One 

 worth five hundred dollars was found in 

 Wisconsin in 1889, and others ranging in 

 value up to three hundred dollars have been 

 found in Vermont, Ohio, Texas, and Ten- 

 nessee. The archasologist will be especially 

 interested in the chapter on aboriginal lapida- 

 rian work in North America, and the general 

 reader will obtain much welcome informa- 

 tion from the concluding chapter dealing 

 with imports, values, cutting of diamonds 

 and other stones, mineral collections, and 

 uses of precious and ornamental stones for 

 silver articles and furniture and for interior 

 house decoration. Mr. Kunz was eminently 

 well fitted to produce this work, as he is the 

 gem expert for Messrs. Tiffany & Co., has 

 prepared several reports on the precious 

 stones of the United States for the Geologi- 

 cal Survey, and is the special agent in charge 

 of this subject for the census of 1890. The 

 magnificent plates showing all the important 

 stones in their natural colors are the work 

 of Messrs. Prang & Co., of Boston. The 

 many other engravings show articles of abo- 

 riginal production, forms of crystals, etc. 

 The book is of standard scientific value, giv- 

 ing as it does the mineralogical characters 

 and chemical analyses of the stones treated, 

 and its handsome form makes it worthv a 

 place in the finest library. 



Food in Health and Disease. By J. Bur- 

 net Yeo, M. D., F. R. C. P. Philadel- 

 phia : Lea Brothers & Co. Pp. 583. 



No one who examines this book can fail 

 to be astonished at the amount of informa- 

 tion that is here compressed within the lim- 

 its of a small volume. Of course, the author 

 has not put all that is known about dietetics 

 between its covers, but he has gone over the 

 ground with remarkable thoroughness. He 

 describes the preparation, cooking, and pre- 

 serving of food, tells the chemical composi- 

 tion and the special value of each of the com- 

 mon articles of food, the proper food for the 

 individual at each period of life, from in- 

 fancy to advanced age, tells how large num- 

 bers of persons may be fed cheaply and well, 



as in prisons, camps, and on board ship, and 

 gives dietaries for all the principal diseases. 

 " I have thought it desirable," says Dr. Yeo 

 in his preface, " to enter fully and in detail 

 into the important subjects of army and pris- 

 on dietaries, school dietaries, and feeding 

 during the critical period of infancy and 

 childhood. In connection with the first of 

 these subjects I have been at pains to pre- 

 sent as fully as possible the admirable sys- 

 tem of feeding our soldiers at home stations, 

 so ably devised and carried out by Colonel 

 C. J. Burnett — a system which may serve as 

 a model of wholesome, economical, and in- 

 telligent feeding." Dr. Yeo gives a warning 

 against the tendency to overfeeding in adults, 

 especially those who habitually make little 

 physical exertion. The habit of drinking 

 milk with the meals is one way in which the 

 proper amount of food may be exceeded 

 inadvertently. In the part of the volume 

 devoted to food in disease, besides general 

 directions applicable to different diseases, 

 there are given various "cures " known by the 

 names of their originators. An appendix 

 contains tables of hospital dietaries, and an- 

 other contains a list of select recipes for 

 invalids' dietary. 



A New Medical Dictionary. By George 

 M. Gould, M. D. Philadelphia : P. Bla- 

 kiston, Son & Co. Pp. 519. Price, $3.25. 



The aim and scope of this work can be 

 best told by quoting from the preface. The 

 author's purpose has been u to include those 

 new words and phrases created during the 

 past ten years — a period rich in coinages — 

 which appeared destined to continuous usage. 

 ... To frame all definitions by the direct 

 aid of new, standard, and authoritative text- 

 books, instead of making a patchwork of 

 mechanical copying from older vocabularies. 

 While neglecting nothing of positive value, 

 to omit obsolete words and those not perti- 

 nent to medicine except in a remote or fac- 

 titious sense. To make a volume that will 

 answer the needs of the medical student and 

 busy practitioner, not only by its compact- 

 ness of arrangement and conciseness of defi- 

 nitions, but also by its convenience of size 

 and price." A notable feature of the work 

 is its many tables, which comprise abbrevia- 

 tions, affixes, arteries, bacilli, ganglia, leuco- 

 maines, micrococci, muscles, nerves, plex-
