A substance that causes sepsis or putrefaction.
1750, John Pringle, Further Experiments on Substances Resisting Putrefaction, in 1809, Charles Hutton, George Shaw, Richard Pearson (editors), The Philosophical Transactions of the Royal Society of London, Volume X: 1750—1755, page 86, But, in the prosecution of this subject, he had met with very few real septics; and found many substances, commonly accounted such, of a quite opposite nature.
Acid-base balance data revealed moderately abnormal metabolic balance for both septics and nonseptics (in either direction) with normal respiratory balance or mild alkalosis.1983 May/June, Ivo Giovannini, Giuseppe Boldrini, Marco Castagneto, Gabriele Sganga, Giuseppe Nanni, Mauro Pittiruti, Giancarlo Castiglioni, “Respiratory Quotient and Patterns of Substrate Utilization in Human Sepsis and Trauma”, in Journal of Parenteral and Enteral Nutrition, volume 7, number 3, →DOI, page 227:

A septic tank; a system for the disposal of sewage into a septic tank, a septic system.
The question is whether there are any spatial differences in how septics impact water quality, and whether these spatial variations should be considered when regulating septic improvement or removal.2008, Alexey Voinov, Systems Science and Modeling for Ecological Economics, page 244:

Mathematics, Sciences A mathematical object (function, curve, surface, etc.) of degree seven.
Enriques states that it is possible to construct a family of septics with a singular curve of degree 7 and genus 4 having a triple point that degenerates to the above configuration[…].2002, Ingrid C. Bauer, Fabrizio Catanese, Roberto Pignatelli, “Canonical Rings of Surfaces Whose Canonical System has Base Points”, in Ingrid C. Bauer et al., editors, Complex Geometry: Collection of Papers Dedicated to Hans Grauert, page 66:
Now consider the two septics C = U⁷ᵢ₌₁Cᵢ, D = U⁷ᵢ₌₁Dᵢ and note that for i = 1,2,3,4,5,6 the lines Cᵢ and Dᵢ are parallel, so that the intersection of two septics S' consists of 6⁶^([sic]) + 6 + 1 = 43 points and it is the singular set of a foliation of degree 6.2003, Antonio Campillo, Santiago Encinas, “Two Dimensional Complete Ideals”, in Luchezar L. Avramov et al., editors, Commutative Algebra: Interactions with Algebraic Geometry: International Conference, page 71:
