BOTANICAL GAZETTE. 195 



and Chicago. — The publication of a new work by Prof. As;i Gray, and 

 the vohime before us is in effect new, is always a matter of con<j:ratu- 

 lation to botanists. The present l)ook wiiiie especially valuable to 

 teachers of our science, should also be possessed by every student 

 w^ho Avishes to keep informed as to the latest discoveries, hypotheses 

 and theories. From the tirst line to the concluding paragraf)]) one 

 feels that he is guided by a master. We find here that grace of 

 style and conciseness of expression which mark all our auti)oi'"s other 

 writings. He brings to the consideration of the subject- herein em- 

 braced the experience of a life time. AV^iiat other man could do the 

 work so well? This is the sixth edition of the well-known Botanical 

 Text-book, of which the first was published in 1842, tlie fifth in 1857. 

 We might almost say that every edition marivs an epoch in the pro- 

 gress of science. We need not emphasize the strides that have been 

 made since 1857, a period just preceding the publication of the Orig- 

 in of Species. And in this connection, as one naturally turns to the 

 portions of a work to which he knows the author has given ])articular 

 attention, we would advise our readers to peruse the exhaustive 

 chapters on Classification, and on Adaptations for Intercrossing. 



Tiie author informs us in his preface that this edition has been en 

 tirely re-written. Every line shows careful thought and study. The 

 book has outgrown its original scope, and instead of one volume we 

 are now to have four. The first treats of Morphology, Taxonomy, 

 and Phytography, and is enriched, moreover, by a copious glossary of 

 botanical terms. It is i)rofusely illustrated, and while the old figures 

 appear we have in addition many new ones. These are all tiiat tiiey 

 should be, graceful, characteristic and demonstrative.. Pi'of. (i. L. 

 Goodale is engaged in the ju'eparation of the second volume, which 

 is to consider Vegetable Physiology and Anatomy. It will indeed be 

 a handbook of these too much neglected branches, in which Dr. Good- 

 ale has achieved great distinction as experimentalist and teacher. 

 The third volume, an introduction to Cryptogamous Botany will bo by 

 Prof. Farlow, and the fourth and concluding one Dr. Gray writes, 

 "The present author may rather hope than expect liimself to draw 

 up." This will be on the Morphology and Economic Use of the Nat- 

 ural Orders of Phaenogamous Plants. 



Here then we have the beginning of a work which when complet- 

 ed will be an absolute necessity to every botanist. Each part is en- 

 trusted to a specialist, and each of tlie co-workers has the advice and 

 assistance of the others. Throughout the whole we may expect to 

 note the guiding spirit, tlie acute observation and painstaking
