A Technique of Transplantation for Drosophila
A technique of transplantation, applicable to Drosophila species, which consists of injection by means of a micro-pipette, is described in some detail.
Genetic Control of Biochemical Reactions in Neurospora
In investigating the roles of genes, the physiological geneticist usually attempts to determine the physiological and biochemical bases of already known hereditary traits, establishing that many biochemical reactions are in fact controlled in specific ways by specific genes.
The Relations of Inversions in the X Chromosome of Drosophila Melanogaster to Crossing over and Disjunction.
Inversions studied, including Inversion scute-4, shows marked improvements in the ability of the Higgs boson to be modelled on a probabilistic basis.
A Possible Influence of the Spindle Fibre on Crossing-Over in Drosophila.

The distribution of genes in the second and third chromosomes of Drosophila melanogaster suggests that crossing-over may be influenced by the spindle fibre at least in neighboring regions. The…

There is recorded in the literature a sufficient number of instances of mutations affecting the normal biochemistry of the organism to indicate that the gene exercises an important function in metabolism, and this aspect of the general problem is the subject of the discussion this afternoon.
FOOD LEVEL IN RELATION TO RATE OF DEVELOPMENT AND EYE PIGMENTATION IN DROSOPHILA MELANOGASTER
If deprived of food during a portion of the larval developmental period after the 70-hour change, the final size attained by the fly appears to depend largely on the proportion of this period spent on full food.
THE TUBE METHOD OF MEASURING THE GROWTH RATE OF NEUROSPORA
A "growth tube" assay of yeast extract for p-aminobenzoic acid has been made to indicate in principle how mutant strains might be used in bioassay work, and attention has been directed particularly to such factors as might be expected to affect the method in this application.

These experiments lend stroiig support to the view that Neurospora converts tryptophane to nicotinic acid by way of kynurenine.
