There appears to be an intimate relationship between the glottal 

 stop and the trill r. Frequently, particularly with reduplicated 

 stems, a glottal stop is apparently changed to an r. 



There is frequently an effort made to keep morphological elements 

 separate and to prevent their blending. Thus there will often be 

 a pause, a perceptible hesitation, between two such elements, some- 

 times between two vowels, at other times between a consonant and 

 vowel, which has sometimes been wrongly indicated by a glottal 

 stop. It is best denoted by a period on the line, . . As already 

 stated, this device is adopted for the principal purpose of separating 

 morphological elements and preventing confusion among them. 



Practically all dual consonantal combinations are permitted me- 

 dially. Examples of the majority of possible combinations have 

 been found and there is no indication that any of the others are 

 forbidden, unless it may be h as the first member of a combination. 



SI SCOFE 



The most frequent cause of consonantal combination is syncope. 

 This is a very active process in Tepecano. While the rules have 

 not been worked out in detail, it may be suggested that a short 

 medial vowel will generally disappear to permit the combination of 

 flic adjacent consonants, provided, of course, that this will not entail 

 an initial or final consonantal cluster. This process appears in 

 strongest force in the case of reduplicated stems, where an appar- 

 ently possible but unconsummated consonantal combination is ipse 

 facto good evidence of the length of the intervening vowel.

 before i. In the grammar of the Lower Pima (Smith, pp. eit.) there seems to be no such 

 distinction made. Likewise Rnssell (op. c't < terms c (sh) a rare sound in I riper Pima.
