1893.] MICROSCOriCAL JOURNAL. 145 



cyclopcedia of microscopy. It is very convenient and contains 

 much more information than the indexes published at the end of 

 each volume. 



For instance, mention could not be made in the usual index of 

 the various methods described in articles v^hose titles are general. 

 A paper on manipulation, mounting, staining, section cutting, etc., 

 would furnish me a great number of slips. But these minute 

 points are obtainable only by reading carefully every part of an 

 article ; but this pays in the knowledge which one accumulates. 

 I have learned more of the subject the past three weeks, while in- 

 dexing some back volumes, than I could have learned in many 

 years of careless reading. All newspaper clippings are numbered 

 consecutively and indexed with the rest. A. P. Weaver.

{i6) Microscopical Titles. — This scheme will be of un- 

 doubted usefulness to writers on microscopical topics. I shall 

 probably use it in order to test it in practice. But to the general 

 reader, while the list will be useful, the labor of cutting and ar- 

 ranging will perhaps seem beyond what he wishes to put forth. 

 I enclose a list of titles and can send more if called for. 



Edward Gray.

(17) Titles. — My opinion is that this leaflet is a good thing. 

 I will use only a part of it. as I have but few books on microscopy. 

 The type is too small and the titles too crowded. I would rec- 

 ommend using the larger type, and some leads and a rule between 

 the items. Geo. R. Lumsden.

CiS) Titles. — I am pleased with your scheme of getting up an 

 index to microscopical literature, and can supply you with 100 

 or more titles. H. M. Whelpley. 



St. Louis, Mo., March 17. 



(19) Titles. — By all means continue your titles of microscop- 

 ical publications. M. D. Ewell. 



Chicago, March 16. 



(20) Titles. — I enclose a list of books on microscopical tech- 

 nique taken from my card catalogue which may be of service to 

 you in continuing your list. Geo. C. Freeborn.

(31) Titles, — I think your plan of a bibliography of the micro- 

 scope a very good one. Should you continue it, I will gladly 

 send you some titles from a bibliography which I have been col- 

 lecting for several years. E. G. Love. 



New York, March 18. 



(22) Titles, — Your suggestion as to titles is excellent. To 

 show my appreciation of its wisdom and value I enclose a list of 

 titles. If others will do the same it will prove very useful. If 

 the titles were spaced asunder there would be no fault found, I 

 think. O. S. Westcott.
