PATENTED. 
'T'HIS most ingenious invention is designed for the rearing of all living 
objects of Natural History, and is of the greatest assistance in the 
scientific study (under the most favourable conditions) of the wonderful 
economy and transformation of nature, and so constructed as to enable the 
specimen to develop to the fullest perfection. 
No. 1, as illustrated, is a Ventilated Lid or Cover, with deep rim (which 
fits inside of glass case, No. 2 ), deep enough to prevent larvae from spinning 
on the glass, thus allowing the cover, with cocoons and pupae attached, to 
be removed for inspection, or stored away in large cages until they emerge. 
No. 2, Glass Case, which permits the full power of light to freely enter 
on all parts of the specimens from every point of view. 
No. 3, The Base (which the Case No. 2 fits into) is made to contain earth 
for the growing of plants, or for the use of those insects who bury during pupa 
state. The bottom of the base is perforated to allow the air to pass through 
the case, thus preventing over-heating, steaming, or mildew of the specimens, 
earth, or plants, which is very difficult to prevent in other forms of cases. 
No. 4, Is a small movable Pot to contain water in which the stems of food 
plants may be placed that cannot be grown in the case, such as the cuttings 
of trees, etc., which last for a considerable time in this case. 
The Pot has a perforated india-rubber cover to prevent the larvae from 
entering the water.
