A determinação dos números de indivíduos mínimos necessários na experimentação genética Anais da ESALQ
Brieger,F. G..
The main object of the present paper consists in giving formulas and methods which enable us to determine the minimum number of repetitions or of individuals necessary to garantee some extent the success of an experiment. The theoretical basis of all processes consists essentially in the following. Knowing the frequency of the desired p and of the non desired ovents q we may calculate the frequency of all possi- ble combinations, to be expected in n repetitions, by expanding the binomium (p-+q)n. Determining which of these combinations we want to avoid we calculate their total frequency, selecting the value of the exponent n of the binomium in such a way that this total frequency is equal or smaller than the accepted limit of precision n/pª{ 1/n1 (q/p)n +...

A influência da alimentação verde na postura Anais da ESALQ
Jardim,W. R.; Trivelin,A. P..
A test was conducted at Poultry Department of "Luiz de Queiroz" School of Agriculture to prove the effect of green feed on egg production. One hundred Rhode Island Red hens at plain laying period were divided in ten pens. The lot A was constituted of pens 1 to 5 and the lot B of pens 6 to 10. During 16 days the pens 1 to 5 did not receive green feed and the pens 6 to 10 received it with abundance. After and for a period of 30 days the situation was inverted. The analysis were made considering, a) the production of all chickens and b) discarding the chickens with irregular laying. In both cases the results were statistically insignificant, proving that green feed did not improve egg production.

A influência dos pigmentos amarelo -laranja de vários alimentos na coloração da gema de ôvo de galinha Anais da ESALQ
Graner,E. A..
The effect of different feeds in comparison with that of maize grains on the egg yolk color was observed. It was found that deep orange and yellow orange maize give satisfactory coloration to the yolk, respectively orange and yellow. The most intense color was observed when green feed was used in combination with deep orange maize. Green feeds as chicory, alfafa, cabbage, welsh onion and banana leaves and alfafa or chicory meal proved to be good in giving orange color to the yolk. Yellow yolk was obtained when Guinea grass or carica fruit were used in the ration. Carrot and beet without leaves did not give satisfactory color to the egg yolk. The observations with other feeds are being continued.

A new race of Dicrurus from the Island Morotai (N. Moluccas) Naturalis
Bemmel, A.C.V. van.
In preparing a Handlist of the birds of the Moluccan islands, I found among the material in the Rijksmuseum van Natuurlijke Historie, Leiden, a race of Dicrurus that needs description: Dicrurus bracteatus morotaiensis nov. subspec. Diagnosis: Distinguished from atrocaeruleus Gray (1860) — Batjan and Halmahera — by smaller culmen and wing. Habitat: Island Morotai (N. Moluccas). Measurements in mm: ♂♂ culmen: 29; 29; 28.5; 28.5; 30 wing: 150; 148; 147; 152; 149 ♀♀ culmen: 27; 29; 30 wing: 149; 147; 145. For comparison the following measurements are given: Halmahera: ♂♂ culmen: 32; 32; 32; 31; 33; 33; 32; 32 wing: 162; 161; 175; 169; 166; 169; 168; 168 ♀♀ culmen: 32; 34; 33; 31; 31 wing: 160; 165; 168; 162; 162 sex inc. culmen: 32; 32; 31; 33 wing: 159; 167;...

A new system of the Cormophyta Naturalis
Lam, H.J..
Some time ago I proposed elsewhere (1) a new system of the Cormophyta. Since the periodical, whose hospitality was my privilege, may not reach many taxonomists who still may be expected to be interested in the proposal, I deem it justified to briefly review the results at which I arrived in the present journal; and this will give me an opportunity to explain one or two points of a nomenclatural nature which, it seems to me, were perhaps somewhat insufficiently elucidated in the paper quoted. As a matter of course, for details as well as for the full argumentation of my views I have to refer to that publication.

A sarna das orelhas dos coelhos Anais da ESALQ
Bergamin,Armando.
A experiência foi realizada com o propósito de encontrar um tratamento eficaz e de fácil aplicação na cura da sarna das orelhas do coelho doméstco. Foram tomados 5 lotes de 3 coelhos e tratados com Detefon, Insect-o-Blitz, Terebentina e óleo, D. D. T. a 10% e vaselina e Querozene. Foram feitas 4 aplicações com intervalos de 4 dias. Chegámos à conclusão de que o melhor tratamento foi o D. D. T. a 10% e vaselina que produziu os melhores resultados e que pode, por isso, ser indicado. A terebentina e óleo também pode ser indicada como eficiente. Quanto aos outros tratamentos é possível que produzam efeitos satisfatórios fazendo-se uma diluição conveniente, afim de atenuar a ação causticante dos ingredientes.

A severidade de corte no sisal e analise tecnológica da fibra Bragantia
Medina,J. C.; Correia,F. A..
In this paper it is presented a detailed fiber analysis of leaves of twenty mature sisal plants taken from four positions on the plant: 1) first developped leaves (75°); 2) leaves usually cut for fiber extraction (50°) ; 3) leaves adjacent to the central bud (25°) ; and 4) young leaves not yet unfolded from the central bud (0°). The results herein reported are against the prevailing opinion that the sisal leaf only matures after it has unfolded from the central bud. Neither the physical nor the chemical fiber characteristics were adversely affected even if cutting was carried out up to the very young leaves. This practice, however, cannot yet be advised, as it desirability also depends on the effects of the severe cutting upon the subsequent rate of growth...

Água inativa de alguns tipos de solos do estado de São Paulo Bragantia
Franco,Coaraci M.; Mendes,Heli Camargo.
Using the method of Briggs and Shantz, several types of soils of the State of São Paulo were studied respecting their wilting points. The results obtained are given in the Table I, and show us that we cannot use as wilting point twice the value of the hygroscopicity as given by Camargo and Vageler for the soils of the State of São Paulo.

Alimentação dos marrecos II: ração de marrecas para postura - Ração balanceada x Ração grosseira, barata Anais da ESALQ
Bergamin,Armando.
The author studied in this paper the substitution of a balanced ratio for an economic ratio composed of 50% of sugar beet and 50% of balanced ratio, in feeding ducks egg production. It was found that the combination had no advantage since the production of eggs was very much reduced.

An account of the Blattidae (Orthoptera) from Celebes, the Moluccas, and new Guinea Naturalis
Bruijning, C.F.A..
The Blattid fauna of Celebes, the Moluccas, and New Guinea, a region which from a zoogeographical point of view forms an important area of transition, is still insufficiently known. Moreover the literature on the Blattids of this region is scattered in various papers which made it desirable to give a general survey of the hitherto known species of the group from Celebes, the Moluccas, and New Guinea. The present paper deals with the material of Blattidae from the region mentioned above contained in the Leiden and in the Amsterdam museums. I am indebted to Prof. Dr. H. Boschma and Dr. H. C. Blöte of the Rijksmuseum van Natuurlijke Historie at Leiden, and to Prof. Dr. L. F. de Beaufort and Mr. J. B. Corporaal of the Zoological Museum at Amsterdam for placing...
