MICROSCOPICAL AND LANTERN SLIDE 

 CIRCULATING LIBRARY. 



FROiVI time to time a \ery strong desire has 

 been expressed by users of the Lantern and 

 Alicroscope that I should establish some 

 system by which they could oljtain suitable sets of 

 slides for Lectures and Demonstrati\e purposes, 

 and to obviate the heavy e.xpenditure in the 

 purchase of slides they are frequently called upon 

 to make when pre]3aring' for lecture work. 



To meet this desire, I purpose in .September next 

 to open my Entire Stock of Lantern and Wlicro- 

 scopical Slides for Subscription Purposes, thus 

 enabling members of Cluljs, Schools, Institutions, 

 Natural History Societies, etc., to fully ancl 

 completely illustrate (both by Lantern Slides and 

 by e.x:hibition of the actual object under the micro- 

 scope) the Papers and Lectures on Natural History 

 Suljjects to be gi\en during the winter months. 



iMy catalogue for Se|3tember next, now in pre- 

 paration, will enumerate Lantern and Microscopical 

 Slides illustrative of every branch of Natural 

 History as completely as possiljle. Many of the 

 Lantern Slides sent out to subscribers will be 

 Coloured to Nature, The Microscopical Slides 

 will be of the highest educational value, and such 

 as I supply to Educational Institutions throughout 

 the country. 



Slides to the number of 300 per year, supplied 

 in sets as reciuired by subscriljers, w ill Ije sent, post 

 paid, for the Annual Subscription of £1 Is., 

 payable in advance. 



The slides will be sent one or two days prior to 

 the day of the lecture or exhibition, and must be 

 returned the day following the lecture, post paid. 

 Special post boxes will be providecl for this 

 purpose, which will obviate the usual trouble of 

 packing. 



I shall esteem it a favour if intending" subscribers 

 will communicate as early as possible. Lists of 

 additions to my stock will be sent to subscribers 

 from time to time. 



The Pharmaceutical Series of Microscopical Studies 

 in Elementary and Advanced Botany, comprising 48 

 preparations, are published to meet the requirements of
