1887.] MICROSCOPICAL JOURNAL. 159 
engravings of interesting forms, with descriptive text, were donated by Dr. H. H. 
Chase. 
A communication was received from A. J. Doherty, of Manchester, England, the 
well-known preparer of microscopic objects, announcing his intention of visiting this 
city in a few months. Arrangements have been made with him for a series of demon- 
strations of the most approved methods used in the preparing and mounting of objects 
for the microscope, and from the admitted ability of the gentleman in this line his 
discourses cannot fail to be interesting and instructive, A series of slides mounted by 
him, and comprising a wide range of subjects, were shown under a number of micro- 
scopes last evening by J. G. Clark, and the excellence of workmanship shown by these 
mounts elicited the warmest commendation. 
J. A. Sladky, of Berkeley, was duly elected a resident member. 
The useful little device known as ‘Griffith's Focus Indicator,’ was shown by Mr. 
Riedy. Its object is to enable an approximate focus to be obtained almost instantly, 
and to prevent the accidental crushing of a slide or cover-glass by the objective in 
focussing. 
Mr. Norris announced that, through the kindness of Mrs. Ashburner, he had come 
into the possession of a number of exquisite slides, mounted by the late Prof. Ash- 
burner, and comprising a number of preparations of the celebrated ‘original Santa 
Monica’ find. No better disposition could be made of these, Mr. Norris thought, than 
to distribute them among the members of the society, and this he proceeded to do. 
As appropriate mementoes of a departed friend, as evidences of his rare skill asa 
microscopist, and as the last remaining examples of mounts from the remarkable frag- 
ment whose history has been so closely connected with that of the society, these slides 
will be considered treasures by their fortunate possessors. 
Specimens of rich diatomaceous earths from near San Pedro, and from near Santa 
Monica, collected by Mrs. Bush, of San José, were also handed in by Mr. Norris.

NOTICES OF BOOKS. 
A Text-book of Pathological Anatomy and Pathogenesis. By Ernst Ziegler, professor 
in Univ. Tiibigen. Translated by Dr. MacAllister. Three parts complete in one 
volume. New York. Wm. Wood & Co. 1887. (pp. 1091 ; figures 280). 
We are glad to notice the completion by Dr. MacAllister of his translation of this 
most thorough treatise on the subject of pathological anatomy, and its appearance as 
a complete single volume. For the benefit of any who are not familiar with the scope 
of the work through acquaintance with the earlier parts we will present an analytical 
review of its contents. 
It falls into two parts—a general pathological anatomy, treated in seven sections, as 
follows :—1, Malformations ; 2, Anomalies in the distribution of the blood and lymph; 
3, Retrogressive disturbances of nutrition; 4, Progressive or formative disturbances 
of nutrition; 5, Inflamation and inflammatory growths; 6, Tumors; 7, Parasites; and 
special pathological anatomy, in twelve sections, as follows:—1, Blood and lymph; 
2, Vascular mechanism; 3, Spleen and lymphatic glands; 4, Serous membranes; 
5, Skin; 6, Mucous membranes; 7, Alimentary tract; 8, Liver and pancreas; 9, 
Urinary organs; 10, Respiratory organs; 11, Central nervous system; 12, Peripheral 
nervous system. 
The introduction covering the first thirteen pages is a very remarkable essay upon 
the animal cell, its healthy life, and all the various forms of hindrance to healthy life 
to whichit is subject. Itisan admirable summary statement of case from the cell stand- 
point, and is in strict keeping with the thoroughly scientific character of the entire 
work. The author’s recognition of the importance of cell pathology for the science 
of Pathology is well shown in the following quotation (p. 8):—‘ Morbid changes have 
their seat in the cells and in their derivatives, the intercellular substances. It is there- 
fore indespensible to a right understanding of these changes to call in the help of the 
microscope, and with it follow out the cellular and intercellular processes.’ ‘Asa fact, 
the microscope has in countless cases thrown an utterly unexpected light upon these 
processes, and the enormous advance of pathological anatomy in the last quarter of 
a century or so has been brought about simply by the exact attention bestowed upon
