Amonest other animals which I collected in the forests 
of Thuringia and brought over to England, towards the 
end of September last, were several blindworms. Only a 
few days after my arrival here, one of them gave birth to 
nine young ones. ‘'T'wo of the latter died shortly after 
birth, the one being still inside the egg-membranes, the 
other having broken them, but still carrying the yolk- 
sack. Having thus a number of both old and young 
blindworms, and wishing to see for myself actual prepara- 
tions of the pineal eye, which was known to me only by 
diagrams, I resolved to make some sections of that organ, 
hoping at the same time to be able to throw some light 
upon the development of the pineal eye in Anguwis fragilis. 
From an examination of these preparations I was led to 
conclusions which differed in some ways from the existing 
opinions about that organ, and these I intend to bring 
forward in this paper. 
In publishing these notes, I must apologize to those 
authors who have lately written on the pineal eye and 
whose works I do not mention here, for the simple reason 
that I have not been able to see the original papers. If 
my results differ from those given in papers which I have 
not seen, I hope they will give rise to further investi- 
gations. If they agree with them, then this paper must 
be regarded simply as a confirmation of known facts.
