"The name of Edward Nettleship is among the great ones of ophthalmology. He was in the succession of 

 Bowman, von Graefe and Donders, but his mind was of a philosophical cast, and he was particularly interested 

 in hereditary defects, and comparatively early in life he retired from practice in order to devote himself 

 entirely to the study of this subject. His pupils founded a medal in his honour, which, at his request, is 

 awarded for the encouragement of scientific and ophthalmic work. His best memorial, however, has been 

 erected by Professor Karl Pearson, who has devoted one of the fine volumes of The Treasury of Human 

 Inheritance to the subject of hereditary diseases and anomalies of the eye, to stand as a Nettleship Memorial 

 Volume and record of Nettleship 's own work and that of his immediate students and friends. Part I, which 

 was published in 1922... contained an account of the life of Nettleship and dealt with the subjects of retinitis 

 pigmentosa and allied conditions, congenital stationary night-blindness, and glioma retinae. Part II, which 

 is now published, is devoted to colour-blindness, and under the capable authorship of Dr Julia Bell 

 exhibits to the full the high standard of workmanship that we are accustomed to expect of the Cambridge 

 University Press. The volume, indeed, may be considered as an Edition de luxe, which will give equal satisfac- 

 tion to the bibliophile and the man of science. An excellent reproduction of C. Turner's engraving of the 

 portrait of Dalton by Lonsdale forms an appropriate frontispiece, since Dalton was the first to give a scientific 

 description of colour-blindness." — British Medical Journal 



" Diese grossziigige, dem Gedachtnis Nettleships gewidmete Monographic bringt an der Hand einer 425 

 Nummern umfassenden Literatur und der Reproduktion von 235 Stammbaumen, die alle naher nach den 

 Originalien erlautert werden, eine ausgezeichnete Darstellung der Erblichkeitsverhaltnisse der angeborenen 

 Farbenblindheit. Klar und schon ist auch die einleitende historische Darstellung der Lehre vom Farbensinn. 

 Man kann die Verfasserin und den Verlag nur begliickwunschen zu dieser auch in der Form hervorragenden 

 Leistung, der vollstandigsten, die unser Fach besitzt und die dies fur die Erblichkeitslehre so wichtige 

 Kapitel in einer sehr erwtinschten Weise zusammenfasst."

XIII. BIBLIOTHECA TABULARUM MATHEMATICARUM 



being a Descriptive Catalogue of Mathematical Tables. Part I. 

 Logarithms of Numbers. By James Henderson, Ph.D. Double Number. 

 Price 9s. net. 



"This Tract is a first and very substantial contribution to the realization of another of Professor Pearson's 

 projects — the publication of a new bibliography of mathematical tables. It is a descriptive catalogue of all the 

 more important log tables, antilog tables and tables for the calculation of logs or antilogs to a large number 

 of places. 



Anyone who has attempted even on a small scale to examine and describe collections of tables will recognise 

 the magnitude of the task that Mr Henderson has undertaken, and will appreciate the devices which he has 

 adopted in this first and perhaps heaviest part of the work to co-ordinate the results of his researches and to 

 present them clearly and in a reasonable space. Apart from the value of the catalogue as a work of reference, 

 the Introduction and the historical notes throughout the bibliography will render the Tract of interest to all 

 students of logarithms." — Journal of the Institute of Actuaries 



"Even the professional computer of to-day does not find it by any means easy to keep his knowledge of 

 tables up to date. The last two decades have witnessed the complete modernising of our equipment of 

 logarithmic, trigonometrical and calculating tables.. ..The computer is frequently at a loss to know where to 

 turn for information concerning these new tables, and for guidance as to the best tables to use in his particular 

 problems. The work before us is designed to satisfy this much-felt need, and in our opinion, achieves its 

 object admirably. ...Because of the scarcity of comprehensive literature on the subject, and not less because 

 of its intrinsic merits, we welcome Mr Henderson's production." 



Journal of the British Astronomical Association 



"This is a very complete and well executed index to published tables of the logarithms of numbers. 

 Each table is described in such a way as to give the computer all the information he needs to decide whether 

 it would be useful in his work. Conversely, if the computer has definite requirements in mind for any special 

 task, this volume will at once call to his attention the best tables for his purpose. It should be on the shelves 

 of every institution that has a variety of computing to perform." — The Astronomical Journal
