112 NOTES AND MEMORANDA. ney ae ee 
Photographs of Nobert’s Lines—Dr. Woodward, of the United 
States’ Army Medical Department, has just presented to the Royal 
Microscopical Society and to a few private friends, four admirable 
photographs of the above. The first represents the 1st, 2nd, 3rd, and 
4th bands of the 19 band-plate, magnified 1200 diameters by Powell 
and Lealand’s th immersion. The second represents the 8th, 9th, 
10th, and 11th bands of the same plate, magnified 1100 diameters 
with the same objective. The third displays the 13th, 14th, and 15th 
bands of the same plate, magnified 1100 diameters with the same 
objective; and the fourth contains two photos, one a large one repre- 
senting the 19th band of the 19 plate-band, magnified 1100 with 
Powell and Lealand’s 1,th immersion, and the smaller an enlargement 
of part of the other to 2750 diameters. 
The Presidentship of the Quekett Club.—It is arranged that 
Dr. Lionel Beale, F.R.S., is to be the next President of the Quekett 
Club. It is needless to point out what an excellent selection the club 
has made, and we have no doubt that it will tend to strengthen that 
entente cordiale which is now so thoroughly established between the 
Quekett Club and the Royal Microscopical Society. 
Influence of Light on the Cells of Spirogyra.—At the meeting 
of the Academy of Sciences on the 11th of July, the Montyon prize 
for Experimental Physiology was awarded to M. Famitzin for his 
researches, which have determined the precise action of light on the 
increase of the cells of Spirogyra, and on the development of the green 
matter. 
Moller’s Test-slide and the Navicula Lyra Photographed.—As 
illustrative of photo-micrography with the oxy-calcium light, a subject 
reported on by Col. Woodward, of the U.S. army, in our present 
number, the author has sent to the Editor and to the Royal Micro- 
scopical Society exquisite photographs of the above. The representa- 
tion of Naviculais about 4 inches long, and is wonderfully well defined. 
That of Moéller’s curious collection of Diatomaceew is not so good, 
owing to some of the specimens appearing simply as black disks. The 
Navicula is magnified 1000 diameters with Powell and Lealand’s 1,th 
immersion; the test-slide is magnified 35 diameters, with one of 
Wales’ 13-inch object-glasses. 
French Prizes for Microscopical Researches.—At the meeting of 
the French Academy of Sciences on July 11th, the Desmaziéres prize 
was equally divided between MM. Hoffman and Rabenhérst ; the first, 
author of a memoir on Bacteria, and the second for his work ‘ Flora 
Europea Algarum aque dulcis et Submarine.’ At the same time 
“honourable mention ” was accorded to M. Edouard Strasburger for 
two memoirs “ On the Sexual Organs and the Fecundation of Ferns.” 
Blankley’s Universal Revolving Stage.— We give an illustration 
of Blankley’s Universal Revolving Stage, a description of which was 
read before the Royal Microscopical Society, and appeared in this 
Journal,* so that it is only necessary to give an explanation of it here.
