MICROSCOPY. 



Scale of Barbel (Barbus fluviatilis). — Wc 

 give herewith a figure of the very characteristic 

 scale of the Barbel. There are yet a few other 

 scales required to complete our series, and we should 

 be glad to receive thoroughly authenticated speci- 

 mens for that purpose.

Movable Table. — A description is given in the 

 May number of Science-Gossip of a simple and 

 convenient movable table or stand for carrying both 

 ihe microscope and lamp, so that they can be moved 

 about together without disturbing the adjustment of 

 1 he illumination ; and it may be of interest to add a 

 description of another on a similar plan that I have 

 found very satisfactory. It is a circular flat tray, 

 eighteen inches diameter, and about a quarter of an 

 inch thick, made of two or three thicknesses of mill- 

 hoard cut to the circle and pasted together, and 

 covered on one side with black glazed paper, and on 

 1 he other side with cloth or baize (using paste 

 mixed with a little glue). The glazed paper is cut 

 to a larger circle, and turned over the edge on to 

 1 he other side before the cloth is put on, making a 

 neat finish. This stand is light and conveniently 



portable, audi has been' jfound free from Jrisk of 

 warping or injury in several years' use. At a micro- 

 scopical soiree a number of these stands have been 

 used with decided advantage, each microscope with 

 its lamp being on a separate one, so that the exhi- 

 bitors stationed at the back of the line of tables 

 were enabled to adjust any instrument or change 

 the object exhibited whenever desired, by turning 

 round the stand, without interfering with the line 

 of observers in front of the tables. — William 

 P. Marshall. 



British Diatomace^e. — We are glad to see that 

 the second part of Dr. Doukin's work on the Brit- 

 ish Diatomacese has made its appearance, and we 

 trust that now there will be no delay in its regular 

 issue. 



Monthly Microscopical Journal.— The com- 

 pletion of the fifth volume of this indispensable 

 journal, and the commencement of a sixth with the 

 July number, offers an opportunity for all micro- 

 scopists who have not already done so, to order and 

 obtain it monthly. Make a note of it ! 



iEciDiUM statices.— In Science-Gossip for last 

 month you make mention of a cluster-cup {JEcidium 

 statices) new to Britain, found by Mr. B. S. Hill, 

 of Basingstoke. This discovery was reported to 

 the Winchester and Hampshire Scientific and Lite- 

 rary Society at its last meeting. The cluster-cup 

 was found on the sea-lavender growing on the 

 shores of the Solent, the plant infested covering 

 acres of ground. Since then I have found the 

 same fungus, and with it the characteristic Uredine 

 (Uredo statices) in large quantities near Hythe ; 

 the plant infested fringed the low muddy shores of 

 the Southampton Water for miles. I ask the inser- 

 tion of this, as the locality was given near Basing- 

 stoke, which town is twenty-five miles inland. — 

 Arthur Angell, Jim. 



[It was also found plentifully last June at Walney 

 Island, and has been sent us by two correspondents 

 from Lancashire. — Ed. S.-G.] 



Handbook of British Eungi.— This work is 

 now ready for delivery to subscribers complete, and 

 will be in the publisher's hands by the time this 

 journal appears. It is in two volumes, extending 

 to near 1,000 pages, containing upwards of 400 

 illustrations, and will be indispensable to all students 

 of fungi. Subscribers who have not paid their sub- 

 scriptions are invited to do so forthwith, including 

 one shilling fur postage. Subscription copies not 

 claimed before the 1st of October will be charged 

 at the full price. Post-office orders to be made pay-
