aO THE AMERICAN MONTHLY [Jan. 



as birds wltc concerned, in this countr}^ it was a wide 

 field for those pt)ssessing- the opportunity of study, and no 

 doubt a g-reat deal remained to be discovered. The vote 

 was carried with applause. Mr. C. D. Soar exhibited a 

 series of 41 beautiful drawing-s of Hydrachnidee collected 

 at the club's excursions during- the past season, and g-ave 

 a commentary on the life-history of the water mites in 

 general. Many of these mites are most georgeously 

 colored and marked, and the series was much admired. 



Quekett Microscopical Club. 

 The 347th ordinary meeting- of this club was held on Fri- 

 day, December 18, at 20, Hanover-square, Mr. J. G. Waller, 

 F.S.A., President, in the chair. After the usual formal 

 business, Messrs. Swift exhibited a double perforated 

 stop for affixing cracker g-elatine in experiments with 

 color-ground illumination, to fit the diaphragm carrier of 

 the Abbe or other similar condenser, Mr. W. Stokes 

 read a paper "On Multiple Imag-es in Mirrors," illustrated 

 by diagrams. For the removal of these imag-es Mr. Stokes 

 advocated that microscope mirrors should beg-round about 

 1° from parallelism when, on rotating- the mirror in its cell, 

 the images from the reflecting surfaces would superim- 

 pose in a certain position, and so merge into one. A paper 

 "On a New Form of Sub-Stage Color Illuminator," by Mr. 

 J. Rheinberg-, was read for the author by Dr. Measures. 

 It was shown that the color contrasts obtainable with this 

 instrument were practically unlimited. A discussion fol- 

 lowed. Mr. Nelson read a "Note on Some New Lenses," 

 pointing out the fallacy of the term "aplanatic" as applied 

 to the ordinary triplet mag-nifiers. Votes of thanks were 

 g-iven for these several communications, and the proceed- 

 ing-s terminated. 



It is stated that Mr. C. R. Bishop has authorised the 

 the trustees of the Bishop Museum to expend 750,000 dol- 

 lars in building- an aquarium and marine biological station 

 at Honolulu for the study of marine life in the Pacific. 

 Prof. W. T. Brig-ham is prepared to complete the plans.
