the table, including an egg found in the pouch of a female 
Echidna, in support of the theory that the Echidna, although a 
milk-giving animal, lays eggs which are hatched in the pouch.” 
In the same paper, of the 6th, Dr. Haacke (director of the 
South Australian Museum), publishes a notice alluding to the 
telegram and his own coincident announcement, and adding 
that his discovery of the eggs was made on the 25th of August 
last, in the mammary pouch (not in the uterus) of a living Hchidna 
received about the third of the same month from Kanga- 
roo Island through Mr. A. Molineux.” Dr, Haacke also remarks 
sidge that the Monotremata (to which class the animals referred 
o belong) are oviparous, adding the request that the information 
be sent to the British Association, then in session at Montreal. 
The telegram adds that Mr. Caldwell is now in Northern Queens- 
land, pursuing his investigations, at a station named Dangangald, 
two days journey from Camboon. Mr. Caldwell is the first recip- 
ient of the Balfour travelling Fellowship (established in honor of 
the late Professor Balfour) tenable for three years, he being “one 
of the most distinguished students of Natural History Cambridge 
University has produced, and especially capable in embryology: 
His proficiency led the British Association to commission him to 
try to solve the mystery of the Monotremes, and also to make 
- further discoveries with regard to the Ceratodus. Mr. Caldwell 
“is likely to remain in Australia two years longer.” 
Mr. Theodore ‘Gill, in Science for November 14th, reviews the 
history of the idea that the Monotremes were oviparous. He 
mentions that Geoffroy Saint-Hilaire, in 1829, published a paper, 
illustrated by a figure of an egg of the natural size, in the 18t 
volume of the Annales des Sciences Naturelles. It was received 
y him from Professor Robert E. Grant of London, who drew one 
of a nest of four obtained by a Mr. Holmes. Still earlier, the 
Rev. Dr. Fleming, in his Philosophy of Zodlogy (ii, 215) pu 
lished in 1822, remarks that “if these animals are oviparous (and 
we can scarcely entertain a doubt on the subject, as the eggs have 
been transmitted to London), it would be interesting to know the 
manner of incubation”; and his belief led him to separate, in his 
classification of Vertebrates, the Monotremes from the Mammals. 
Mr. Gill states other facts bearing on the subject in his note.
