    Notes: Abstract The construction of an all-weather field cage housing Old World primates (Macaca fuscata) is described. The 40 × 40 foot enclosure includes some simulated aspects of the animals' natural environment thereby encouraging natural behavior. The animals are observed from a tower equiped with one-way glass to eliminate the animals' being aware of observers. By using prefabricated construction and adaptations of standard supplies and equipment, the cage and tower were constructed at a cost of $7,000.

    Notes: Abstract Limnocythere inopinata (Baird) is a Holarctic species, widely distributed in non-marine waters, and mainly occurring in unisexual populations. It displays polymorphic traits which could be useful for taxonomical and (palaeo)ecological purposes, if the origin of these traits could be better understood. Three clones of L. inopinata were cultured in the laboratory under various temperature and salinity conditions (i.e. temperature 15, 20 and 25 °C, salinity expressed as electrical conductivity 400, 2000, 5000 and 8000 μS cm−1). Morphological traits for both the valves (shape and size) and soft parts (11 limb setae) were observed. Field populations from Chinese salt lakes and from Austrian lakes were also compared. The freshwater population from Mondsee and its derived clone M develop larger valves than those of the other two clones, clone N (from Neusiedlersee) and clone S (from Seewinkel, Oberer Stinkersee), which live exclusively in saline (alkaline) water. Parthenogenetic specimens from the freshwater lake Mondsee and sexually reproducing females from the Chinese salt lakes both have sub-rectangular valves with straight dorsal margin; the saline clones and populations have highly arched valves with rounded dorsal margin. No direct effects of temperature or salinity on valve ornamentation (reticulation, nodation) have been found. At least for nodation, a genetic factor seems apparent, as the saline clones N and S are never nodose, while the freshwater animals from Mondsee and the sexual animals from the Chinese salt lakes can be both with or without nodes. In the former case, number and position of nodes are variable. Both absolute and relative length of limb setae can be affected by environmental factors and by genotype, and this is the first time that this has been demonstrated in non-marine ostracods. Based on the present observations and experiments, it is concluded that L. inopinata is a variable, polymorphic species, consisting of a (semi-) continuous morphological cluster, in which both clonal genotypes and sexual haplotypes are nested. Therefore, Limnocythere sappaensis Staplin and L. binoda Huang are considered synonyms of L. inopinata; L. mongolica Daday is a possible synonym; L. sanctipatricii sensu Huang and L. dubiosa sensu Huang from Lake Qinghai are most likely erroneous identifications. Apparently recognisable clones with typical ecologies cannot be allocated a taxonomic rank, as this does not reflect a phylogenetic reality. Such links between recognisable morphologies and typical ecological ranges are useful for palaeoenvironmental reconstructions, but are applicable at a regional scale only.

    Notes: Reaction of 3-Chloro-1,2-benzisothiazolium Chlorides with N-Mono- and N,N-Dialkylanilines3-Chloro-1,2-benzisothiazolium chlorides 1 react with N-mono- and N,N-dialkylanilines 2 to give the 3-phenylisothiazolium salts 3. These thermally split off alkyl halides to yield the 3-phenyl-isothiazoles 4. On treatment with alkali the salts 3 are transformed into the benzophenones 7 via ring cleavage.

    Description / Table of Contents: Oxidation Products of 3-Amino-1,2 benzisothiazolesa and 3-Imino-1,2-benzisothiazolines3-Amino-1,2-benzisothiazoles 1 can be converted selectively into the sulfoxides 2 with nitric acid, whereas oxidation with peracetic acid yields the sulfones 3. The sulfoxides 10 and the sulfones 6 of the isomeric 3-imino-1,2-benzisothiazolines 5 can be obtained from 3-chlorimino-1,2-benzisothiazoline 1-oxides 9. The chemical properties of the oxidized products of both isomeric classes of compounds are totally different. - The compounds obtained by the reaction of 3-chlor-1,2-benzisothiazolium chlorides 11 with hydroxlamine are proven to be the N-oxides 13 of 3-amino-1,2-benzisothiazoles. They can be isolated in the form of their salts 12 and can be rearranged to the isomeric 3-oximmino-1,2-benzisothiazolines 14.
    Notes: 3-Amino-l.2-benzisothiazole 1 lassen sich mit Salpetersäure selektiv in ihre Sulfoxide 2 umwandeln, während die Oxydation mit Peressigsäure zu den Sulfonen 3 führt. Die Sulfoxide 10 und Sulfone 6 der isomeren 3-Imino-1.2-benzisothiazoline 5 können aus den 3-Chlor-imino-1.2-benzisothiazolin-l-oxiden 9 erhalten werden. Die chemischen Eigenschaften der Oxydationsprodukte beider isomeren Verbindungsklassen sind völlig verschieden. - Die durch Umsetzung von 3-Chlor-1.2-benzisothiazoliumchloriden 11 mit Hydroxylamin er-haltenen Verbindungen werden als die N-Oxide 13 der 3-Amino-l.2-benzisothiazole erkannt. Sie können in Form der Salze 12 isoliert und zu den isomeren 3-Oximino-1.2-benzisothiazo-linen 14 umgelagert werden.

    Description / Table of Contents: N,N′-Dialkyl-3-imino-1,2-benzisothiazolinesThe reaction of 3-chloro-2-alkyl-1,2-benzisothiazolium chlorides 1 with primary, aliphatic amines yields N,N′-dialkyl-3-imino-1,2-benzisothiazolines 2. In the case where R1 ≠ R2. the bases 2 exist as an equilibrium mixture of rapidly interchanging constitutional isomers, which in the case R1 R2 degenerate to constitutional topomers. A seperation of the salts 3′ and 3″ (X=ClO4, R1 ≠ R2) is however possible. - The benzisothiazolines 2 react with water to give the 2,2′-dithiodibenzamidines 5, which disproportionate on warming to yield 2 and the 2-mercaptobenzamidines 7. In solution an equilibrium is formed between 5,2, and 7.
    Notes: Die Umsetzung von 3-Chlor-2-alkyl-1,2-benzisothiazolium-chloriden 1 mit primären aliphatischen Aminen führt zu N,N′-Dialkyl-3-Dialkyl-3-imino-1,2-benzisothiazolinen 2. Im Falle R1 ≠ R2 liegen die Basen 2 als Gleichgewichtsgemische schnell ineinander übergehender Konstitutionsisomerer vor, die im Falle R1=R2 zu Konstitutionstopomeren degenerieren. Eine Trennung der Salze 3′ und 3″ (X=ClO4, R1 ≠ R2) ist jedoch möglich. Die Benzisothiazoline 2 reagieren mit Wasser zu den 2,2′-Dithiodibenzamidinen 5, die thermisch wieder in 2 und 2-Mercaptobenzamidine 7 disproportionieren. In Lösung stellt sich zwischen 5, 2 und 7 ein Gleichgewicht ein.
