178 The Microscope. 



begun ia an indifferent way to examine objects without definite pur- 

 pose, to consider this seriously. Material is abundant, the manipula 

 tions necessary at the start are such as are easily acquired; a 

 knowledge of histology is essential in the study of biology, micro- 

 scopical botany, and all of the subdivisions of microscopical science. 

 As helps in this, Gage's " Notes on Histological Methods," together 

 with Strieker's, Schafer's, Frey's, Stowell's and other histologies 

 will be necessary. 



At this point Friedliinder's " Use of the Microscope" will be 

 found useful. When the student has acquired a fair knowledge of 

 animal tissue, he is prepared to decide what particular branch of 

 microscopy interests him the most, and is fitted to begin his 

 researches with a foundation knowledge which will prove of ines- 

 timable value to him. If biology is his choice, let him begin with 

 Huxley and Martin's valuable hand book, Foster and Langley's 

 " Practical Physiology," Foster's " Elements of Embryology," Bal- 

 four's " Comparative Embryology," Packard's " Outlines," with 

 Whitman's " Methods in Microscopical Anatomy and Embryology." 

 If botany is his preference, Poulsen's " Botanical Micro-Chemistry," 

 Bessey's "Botany," Strassburger's " Micx'oscopic Botany," and 

 Behren's " Guide to the Microscope in Botany," will render him ser- 

 vice. Those who interest themselves in bacteriology, will find 

 DoUey's " Technology of Bacteria Investigation," Crookshank's 

 "Practical Bacteriology," and Woodhead and Hare's "Practical 

 Mycology," the necessary hand books. 



Nearly every department has its exponent in the current micro- 

 scopical literature, but an enumeration of all these works would not 

 prove of interest. Sufficient has been said, howevex', to indicate how 

 workers with the microscope may qualify themselves for work 

 which will stand though tested by fire, and by means of which they 

 may be fitted for the highest duties of membership in any scientific 

 body. It is only by careful attention to the minutise that success is 

 ever attained in this life, and success as a microscopist depends 

 upon the careful observance of details, and a correct interpretation 

 of facts, a condition only to be obtained by long and faithful study. 

 But the pathway to these high attainments is not thorny, — no tale 

 of Arabian Nights is half so fascinating, no study so helpful and 

 broadening to the intallect, no work so remunerative in pleasure-giv- 

 ing and personal satisfaction. 



We learn that the microscopical society of Baltimore, Md., 

 which has been in danger of dying a natural death, has, through
