[79] It is impossible here to enter into a detailed consideration of the various views held with regard to the formation of antitoxins. It is needless to remark that the whole matter is one of abstruse technicality and intricacy. These antitoxic bodies gradually increase in the blood and tissues, and their action falls into two groups: (a) antitoxic, which counteract the effects of the poison itself; and (b) antimicrobic, which counteract the effects of the bacillus itself. "In one and the same animal the blood may contain a substance or substances which are both antitoxic and antimicrobic, such, for example, as occurs in the process of the formation of the diphtheria and tetanus antitoxic serums" (Sidney Martin).
[80] Types of bodies possessing positive chemiotaxis for bacteria are the salts of potassium, peptone, glycerine.
[81] Negative chemiotaxis is illustrated in alcohol, and free acids, and alkalies.

They remained abroad for two years, during which time Lady Wortley Montagu wrote her well-known Letters to her sister the Countess of Mar, Pope, and others.
