March 22ud, 1889, but a notice of it appeared in the Abstract 

 two days after the Meeting. 



Confirmatory evidence was soon forthcoming. In November 

 of the same year I got two specimens of Peripatus at Burra- 

 wang ; they were exhibited at a Meeting of this Society on 

 November •28th, and they were drowned on December 14th; in 

 tlie process one of them extruded five embryos considerably older 

 than Dr. Has well's specimen. On September 18th, 1890, a speci- 

 men from the Blue Mountains under similar circumstances 

 extruded three advanced embryos; and in December of the same 

 year from a second lot of specimens from Burrawang some twenty 

 or more embryos were obtained. These were carefully preserved ; 

 and they were shown to Professor W, Baldwin Spencer, who 

 happened to be passing through Sydney early in September last, 

 a few days after I saw the first of Dr. Deudy's four papers ; they 

 were also exhibited at a Meeting of this Society on September 

 30th, and their bearing on the subject at issue pointed out. 



The climax in my experience, however, was reached in quite an 

 unexpected and rather overwhelming manner in January of this 

 year, during a visit to the Blue Mountains, part of the time at 

 Mt. Wilson, where, with the help of Mr. J. D. Cox and Mr. 

 A. G. Hamilton, T got about forty specimens ; the following week 

 elsewhere I was able to increase the number,, and I came back on 

 the 16th with fully 100 living healthy specimens. When collect- 

 ing, young ones were never once met with ; but in getting two 

 females out of rotten wood T accidentally gashed them in the side ; 

 in one case there immediately protruded a moniliform portion of 

 one of the oviducts suggestive of the presence of embryos; the other 

 one was evidently in distress and I kept her under observation, 

 and finally a little later I saw her in the act of depositing four 

 advanced embryos ; these with the two females were promptly 

 preserved. On Jan. 18th I put all the specimens into fresh and 

 more comfortable quarters, keeping them in four separate lots, but 

 there were still no young ones. On Jan. 25th I first noticed 

 young ones, the number steadily increasing day by day, and until 

 young ones were present in each of the four tins ; frequently 

 twenty or more could be seen at once when one of the tins was
