section::::simian blood groups.









































two categories of blood groups, human-type and simian-type, have been found in apes and monkeys, and can be tested by methods established for grouping human blood.









































section::::simian blood groups.:rh blood group.









































the rh system is named after the rhesus monkey, following experiments by karl landsteiner and alexander s. wiener, which showed that rabbits, when immunised with rhesus monkey red cells, produce an antibody that also agglutinates the red blood cells of many humans.

in the 20th and 21st century, figured bass is also sometimes used by classical musicians as a shorthand way of indicating chords when a composer is sketching out ideas for a new piece or when a music student is analyzing the harmony of a notated piece of music (e.g., a bach chorale or a chopin piano prelude). figured bass is not generally used in modern musical compositions, except for neo-baroque pieces. a form of figured bass is used in notation of accordion music; another simplified form is used to notate guitar chords. in the 2000s, outside of professional baroque ensembles that specialize in the performance practice of the baroque era, the most common use of figured bass notation is to indicate the inversion in a harmonic analysis or composer's sketch context, however, often without the staff notation, using letter note names followed with the figure. for instance, if a piano piece had a c major triad in the right hand (c–e–g), with the bass note a g with the left hand, this would be a second inversion c major chord, which would be written c. if this same c major triad had an e in the bass, it would be a first inversion chord, which would be written c or c (this is different from the jazz notation, where a c means the major sixth chord c–e–g–a, i.e., a c major with an added 6th degree). the symbols can also be used with roman numerals in analyzing functional harmony, a usage called "figured roman"; see chord symbol.
