[" Retired. — In a communication to the ' English Mechanic ' of a late date Mr. 

 Wenham, whose name is known to every microscopist the world over, 

 announces that he has retired from microscopy ; that he has given it up and 

 has not looked through an instrument for several months, and has no 

 expectation of ever doing so again. Mr. Wenham offers no explanation of 

 his determination, but however painful it may be to the thousands who have 

 learned to look upon him as one of the immortals in microscopy, from the tone 

 of his letter we are convinced of his sincerity, and accept Ids dictum as 

 final."]

Collecting, Growing, and Examining Fresh-water Sponges.f — In a 

 contribution to a synopsis of the American forms of fresh-water sponges, 

 Mr. E. Potts lias some remarks on their collection and examination. 



In collecting the author has found great advantage in the use of the 

 " scraper-net " in relatively deep water, and in connection with perpen- 

 dicular timbers, &c. This consists of a small net with one part of its 

 edge shaped into a scraper like a garden hoe ; it is attached to a long 

 pole. At depths of two feet or less, great facility of action is gained by 

 wearing high rubber boots, and wading after the specimens, to pick 

 from the bottom stones, sticks or pieces of waterlogged timber, under 

 which they may be concealed. Where the water is deeper, of course a
