Mr. Home's Lecture , &c. 
Fig. 3. The marsupium in the eye of the turkey, attached 
to the bottom of the eye, and connected by a transparent 
membranous union with the crystalline lens ; made visible by 
coagulation in rectified spirits. 
Fig. 4. The marsupium in the eye of the emeu, from New 
South Wales, with a portion of the membrane that connects 
it to the lens ; the marsupium is drawn together at that end 
next the lens, giving it the appearance of a purse, from which 
it probably got the name marsupium. 
Fig. 5. and 6 . Two views of the crystalline lens of the eye 
of a goose, to show the attachment of the marsupium to the 
lens. 
These different drawings are of the natural size of the parts 
they represent. 
present are exactly similar to those shown in the second figure ; and had the paper 
been published in this country, would have rendered it unnecessary. 
The paper is intituled Esposizione Analomica delle parti relative all’ Encefalo degli 
U ocelli, del Sig. Vincenzo Malacarne; it is published in the Italian Transac- 
tions, called Memorie di Matematica e Fisica della Societd Italiana, Tomo VII, 
Verona, 1794.
