Photographs illustrative of the Appearance of the Specimens 



described in his Paper on " Pseudo-polypi of the Colon, 



as seen with the naked eye and under the Microscope " Dr. J. J. Woodicard. 



The President remarked upon the great beauty of the photographs. 



Mr. Crisp exhibited and described Cosson's Dissecting and 

 Observing Microscope (see p. 807), Goltsch's Binocular Microscope, 

 Lacaze-Duthiers' Large Porte-loupe (see p. 939), Nachet's Microscope 

 for the examination of the Skin, &c., and a Microscope by Schmidt 

 and Haensch of Berlin, with movable stages on a similar plan to those 

 described at pp. 880-1 of Voh III. Also some Micro-photographs of 

 various objects by Mr. J. H. Jennings, of Sherwood Piise, Nottingham, 

 taken with the eye-piece in place, so as to avoid the central, more or 

 less marked, flare-spot found to exist when the objective alone was 

 used, the definition, nevertheless, being unimpaired and the photo- 

 graphs sharp. Mr. Jennings, in a letter accompanying the photo- 

 graphs, calls attention to their value for illustrating scientific papers, 

 &c. " The chief exi)ense is the artist, but if the engraver can work 

 from a good photograph by the carbon process or otherwise, the 

 expense is considerably reduced. Lantern slides for lectures can also 

 be easily prepared from the photo-micrograph negatives." Mr. Crisp 

 also called attention to a slide of Foraminifera of exceptional excel- 

 lence exhibited by IVIr. F. H. Balkwill, of Dublin, containing fifty 

 species on a photographed backgi-ound with the name of each species.
