92 The Joirnal of Heredity 



Register of Hybrid Orchids 



An undertaking which should prove of real value to genetists is the foundation 

 by the Royal Horticultural Society of London of an orchid register, to keep an 

 accurate record of crosses made, thus continuing the compilation of data started 

 by Rolfe and Hurst's Orchid Stud Book, published by the Orchid Review of 

 London. 



The new register will be international in character, and compiled in harmony 

 with the Vienna and Brussels Rules of Nomenclature. It is announced in the 

 following letter from the office of the Royal Horticultural Society in Vincent 

 Square, Westminister, London: 



"November 28th, 1913. 



"The President and Council, acting on the recommendation of a Sub-Com- 

 mittee of the Orchid Committee, have decided to establish a Register of Hybrid 

 Orchids at Vincent Square. Mr. R. A. Rolfe, of Kew, has been appointed Re- 

 corder. The Register will inckide all known Orchids. 



"The President and Council accordingly invite Orchid raisers and growers 

 amateur and professional, to bring their Hybrids, when in flower for the first time 

 (even though they may not then be sufficiently developed to enter for award), 

 and to enter the name and parentage of the plant, together with the exhibitor's 

 name and address, on a Registration Form, which can be obtained from the 

 R.H.S. Office, Vincent Square, S.W. This Registration Form should be sent 

 with the plant, and it will be placed before the Orchid Committee, who. after 

 satisfying themselves that the name is in order, will enter it on the Register. 

 Once so recorded the name must be recognized for all crosses of similar parentage 

 when subsequently shown, unless valid reason can be otherwise produced. 



"W. WiLKS, Secretary." 



Color Inheritance in Pigs 



Reviewing the observations made in Germany and the United States on the 

 inheritance of color coat in pigs, Gustav Frohllich describes the general conclusions 

 in the Berlin Journal f. Landwirthschaft, LXI, 3, according to the Bulletin of 

 the International Institute of Agriculture, Rome: ►^ 



It appears that in the first filial generation of crosses the following are dominant : 



I. White of Improved German Swine (Edelschwcin) over: 

 white and black of Hanoverians 

 black of Berkshires 

 greyish-black of European wild j^igs 

 greyish-black of Comwalls 

 red of Tamworths. 

 black of Caucasian wild pigs. 

 II. Greyish-black of European wild pigs over: 



red of Tarn worth. 

 III. Black and white of Hampshires over: 

 red of Tamworth. 



Importance of Genetics 



I venture to express the conviction, that if the facts now before us are care- 

 fully studied, it will become evident that the ex])erimcntal study of heredity, 

 pursued on the lines Mendel has made possible, is second to no branch of science 

 in the certainty and magnitude of the results it ofTers. This study has one 

 advantage which no other line of scientific inquiry ])ossesses, in that the special 

 training necessary for such work is ca.sily learnt in the practice of it, and can be 

 learnt in no other way. All that is needed is the faithful resolve to scamj) noth- 

 ing. — William Bateson: Mendel's Principles of Heredity (1902).
