but hardly less to the intelligence, zeal, and untiring energy of Pro- 

 fessor Goode and his assistants, who literally worked night and day in 

 order to be ready for the day fixed for the opening of the Exhibition. 



I shall naturally have occasion to write again and more fully on this 

 topic when more perfectly informed, but could not deny myself the 

 pleasure of reportiug to you the impression already made in this inter- 

 national competition by the genius for organization of which our coun- 

 trymen have here given proof, a faculty certainly not the lowest among 

 those that distinguish the social and civilized man.

106— A MEW FISII-IIATCIBING APPARATUS. 



By von LA VALETTE ST. GEORGE.* 



[From a letter to Prof. S. F. Baird.] 



The hatching apparatus which, at my request, was sent to you by the 

 Prorector of the Anatomical Institute, Professor Nussbaum, was in- 

 vented by me and has been described in the Record of Microscopic 

 Anatomy, Vol. XXI.t 



The apparatus is intended for the breeding of Salmonidcv, and princi- 

 pally for small hatcheries and for the owners of ponds and creeks who 

 have any running water and desire to have them stocked with young 

 Salmon i (he. The operation of the same is quite simple. After the two 

 troughs have beeen put one into the other, the impregnated eggs, to the 

 number of 5,000, are placed on the wire bottom of the inside trough, 

 and the opening of the receiving pipe ou the outside trough is put under 

 a stream of water. Through this pipe the water flows in and must 

 circulate around the eggs from below. Passing through the wire on 

 the sides of the inside trough, it is discharged on the opposite side of 

 the entrance. The opening for the outlet of the water being higher 

 than the sides of the wire openings prevents the young fish from float- 

 ing against them. A sieve in front of this construction is quite un- 

 necessary. 



In Germany many hundreds of this apparatus are in use. They are 

 practicable and are much praised. For the purpose of encouraging the 

 distribution of the apparatus I have not had it patented.
