years. This is not stated to find the least fault with any- 

 body for not doing more than he can, but as a curious 

 little example of the amount of work required to carry 

 on the Club, and as a hint, perhaps, to any members who 

 may happen to imagine that the oSicers lack only incli- 

 nation in order to set an example of promptness in 

 everything. 



It would be impossible to specify all to whom we are 

 indebted for contributions and assistance of various 

 kinds in preparing this series. Those who supplied full 

 boxes of slides, with elaborate notes, were Drs. E. J. At- 

 tinelli, J. M. Lamb, George A. Rex, F. A. Rogers, S. Gr. 

 Shanks, W. H. Sylvester and D. B. Ward, Professors 

 Charles H. Clark and H. N. Conser, and Messrs. E. A. 

 Hill, J. D. Mallonee and Lewis Woolman. Photographs 

 more than equivalent to full boxes of slides were fur- 

 nished by Dr. D. B. Ward and Messrs. Frank Ritchie, 

 George E. Ashby and Thomas Christian. Many notes of 

 professional grade and authority, were furnished for 

 slides that required them by Professors Harry M. Kelly 

 and Henry B. Ward, and Dr. S. G. Shanks. The present 

 writer, besides the constant care and labor of keeping 

 up the work during its whole progress, having long been 

 unable to give any time or thoughts to preparing slides, 

 tried to do his share by contributing about 150 pages of 

 typewriter notes, double close, which would make 300 

 pages as usually spaced. As many were prepared with 

 much care, the labor involved was considerable. Sev- 

 eral of these, being intended for general reading, have 

 been published in the journals as explained elsewhere. 



Under the stimulus, perhaps, of the work on the spec- 

 ial series, the last set of circuit boxes was of more than 

 ordinary importance. Subsequently, individual special 

 boxes of value have been contributed by Professors 

 Charles H. Clark and Harry M. Kelly, Mr. F. F. Forbes 

 and Dr. D. B. Ward.
