REPORT OF NEW JERSEY STATE MUSEUM. 35 
1st. The development of . the malarial parasite from actual 
photographs of blood-corpuscles taken from an infested pa¬ 
tient. 
2nd. The characteristic breeding places of the various pesti¬ 
ferous forms found in New Jersey. 
3rd. The photographs of those who have been engaged in 
the mosquito campaign in the State. 
4th. The methods employed in the work of actual control. 
It is assumed throughout that whenever a community real¬ 
izes the existence of a condition detrimental to its interests 
it will at once strive to remove those conditions and this brings 
out 
5th. Samples of educational work done by publications of 
the Experiment Station and direct aid given by preparing 
maps of drainage schemes for mosquito breeding localities, 
etc. 
On the series of table cases there are 26 of the unit museum 
boxes containing specimens. These specimens illustrate the 
commoner species of mosquitoes found in the State, their 
various stages and their natural enemies. Great care has 
been paid to the methods of exhibition and some of these are 
altogether original. Two of the boxes contain the common 
fresh and salt water minnows that feed upon the wrigglers 
and these are shown in vials glued to a glass strip, with a 
white background, so that they appear in a natural, swimming 
position. In each case the label gives not only the name of 
the fish, the character of the waters where found, but also a 
concise statement of how it is .useful. 
In fact throughout the Exhibit the explanatory labels form 
a text in which the whole subject is explained. The report 
already referred to shows what was done, in words, illustrated 
by figures; this collection shows the same thing by actual 
specimens and photographs explained in the labels. 
In connection with the cases of salt water “ killies ” one 
end of the exhibit case represents a salt marsh in miniature— 
one-half with breeding pools for the migratory mosquitoes, 
the other drained naturally, by “ fiddler crabs ” and the like. 
The aim here is to show that there is a large section of ‘ ‘ safe 
marsh and that the problem is not so large as, at first sight, 
it appears to be. The association of marsh and fish is to bring
