To meet a similar need in the Department of Entomology, it was designed 

 to duplicate the first house, with all items, except in the position of the high 

 wall bench. The plans as here shown give the ground and sectional views 

 as prepared to meet the specifications prepared by the writer. Unfortunately

the state legislature did not make any appropriation, at its last session, which 

 could be used for the above purpose. Hence we have only the plans and 

 experience derived by correspondence, to make use of when the opportunity 

 arises. But as the house, as designed, includes some features not previously 

 noticed elsewhere, and is in a sense a laboratory, it may be appropriately described 

 in the Journal. Frederick H. Blodgett.

Ruge {Deutsche med. WcJmschr., Leipzig, 1903, No. 12) refers to Ross's 

 recently published method of using thick layers of blood and staining with eosin 

 (fifteen minutes) and methylene-blue (a few minutes), in greatly facilitating the 

 demonstration of the presence of the malarial parasite. He strongly recom- 

 mends it, and urges its superiority to the older method of thin films. He thinks 

 it to be an improvement, however, to fix the film first. This he does by placing 

 it in 1 per cent, formalin, then in ^4 to 1 per cent, acetic acid, and then in 2 

 per cent, formalin. Elegant preparations are not given, but the parasites stand 

 out prominently and are easily found, particularly crescents, which are often so 

 sparingly found in thin films. He thinks that Ross's method is a great saving 

 of time and trouble and is more sure. — Edinburgh Medical Journal.
