398 Notes and Memoranda. 



"P.S. — Since writing the above I have again seen my informant, 

 and. placed before him my books of photographic portraits. In the 

 first book he did not recognize the likeness of the man he saw in 

 the interior, although it contained a very fine side view of Dr. 

 Livingstone. In the second he at once pointed out a staring 

 likeness of Livingstone, which I kept as a caricature, and said, 

 ' That is the man. But,' he added, ' come to Bagamayo and see 

 my master and the other men ; they have seen him also, and will 

 tell you all they know.' 



" Suspend your opinion for a little, Mr. Churchill, and I go in 

 two days to Bagamayo to make inquiries. Please communicate 

 this view to Mr. Webb, Miss Livingstone, and other friends, but 

 until my next maintain some caution.

ROYAL MICROSCOPICAL SOCIETY.— Nov. 1 3. 

 James Glaisher, Esq., President, in the chair. 



J. Gorham, Esq., read an interesting paper on a peculiar 

 venation chiefly traceable in the leaves of certain composite, of 

 which the marginal veins found in Eryngo offered an interesting 

 specimen. 



At the close of the regular business the meeting was made 

 special to alter the bye-laws. In future, the entrance-fee will be 

 £2 2s., and the annual subscription £2 2s. The composition fee 

 for new fellows, £21. 



NOTES AND MEMORANDA. 



Boss's New Foub-inch Objective. — Mr. Boss has very judiciously decided 

 on meeting the demand of microscopists for a low-power object-glass, adapted to 

 viewing large live objects, polyzoa, etc., and has produced a four-inch combination 

 of great merit and utility. Many highly interesting objects — including ana- 

 tomical preparations, entire insects, small star-fishes, sponges, corals, etc. — can be 

 shown better with this glass than with any other we have seen. With the A 

 eye-piece of Mr. Ross' series it takes in an object 7 — 16" in diameter, and the field 

 is beautifully clear and flat. With deeper eye-pieces a higher magnification may 

 bo obtained, accompanied by much greater penetration than deeper objectives 

 and lower eye-pieces will give, which is an immense advantage in many investi- 

 gations. Mr. Ross has not hitherto, like Messrs. Beck, given his instruments 

 enough rack-room for such low powers. He can, however, by a simple arrange- 

 ment, accommodate the new glass in a perfectly satisfactory way. Every 

 microscopist who sees the working of this four-inch glass will infallibly desire to 

 be its possessor. 



Cheap Compeessoeiusi and Slide-cells. — At the suggestion of the Editor, 

 Mr. Curteis (Mr. Baker's) has turned his attention to the manufacture of Com- 

 pressoriums, which, while not pretending to all the convenience and accuracy of 

 the most expensive kinds, will meet the average requirements of students at a
