able me to determine their species. They are undoubtedly a chair 

 (salvelinus). The vomerine teeth being absent, they will undoubtedly 

 improve our British charrs, but I fear the cross with S. salar will be 

 sterile.

u You will be glad to hear that the cross between S.fontinalis and the 

 Loch Kannoch charr, S. struanensis, which I made three years ago, will 

 prove fertile. The milt in a male, examined by Mr. Day (the product 

 of S.fontinalis female and S. struanensis male), this week being fully 

 developed and the most beautiful hybrid I have yet produced. A cross 

 between S. Jevenensis female and S.fontinalis male also shows unmistak- 

 able signs of fertility. 



" I propose to ship 100,000 S. levenensis ova the week commencing No- 

 vember 24. These eggs differ from the fontinalis in requiring a much 

 larger supply of water, aud it is absolutely necessary they should in no 

 case be laid down so as to lie one above another. The water over them 

 should not be more than half an inch, with a supply of two gallons a 

 minute; size of trough, 7 feet by 20 inches. They will asphyxiate in 

 inches of water; temperature, 45° F. ; date, a week before hatchiug. 

 Fontinalis ova under the same circumstances hatch perfectly. This 

 was a test experiment, and has been repeated with the same results 

 seven years running."
